About HAYNES HR-160 (UNS N12160, Alloy HR160) Heat-Resistant Nickel-Cobalt-Chromium Alloy

HAYNES HR-160  (UNS N12160, commonly known as Alloy HR160) is a high-performance, high-temperature corrosion-resistant nickel‑cobalt‑chromium alloy engineered specifically for the most severe industrial operating conditions.Unlike conventional stainless steels (such as 304, 316, 310S) and standard heat‑resistant alloys (including Inconel 600 and Inconel 601), HR-160 has excellent, industry-leading resistance to the most common forms of high-temperature degradation, including sulfidation, chlorination, vanadium corrosion, and attack from molten salt deposits because of its improved chemical composition.Its very high chromium (26–30%) and silicon (2.4–3.0%) content forms a dense, adherent, self‑healing protective oxide layer on the surface, even under continuous long‑term high‑temperature service.This strong, impermeable film creates an effective barrier against aggressive corrosive media, making HAYNES HR-160 the best choice material for important parts that demand reliable, long lifetime in harsh environments where other alloys experience premature failure.

HAYNES HR-160 International Grade Cross-Reference & Equivalent Standards

Industrial buyers around the world refer to HAYNES HR-160 using different national designation systems, based on their region and applicable engineering codes.The table below is Jiangsu Liangyi’s proprietary cross-reference list compiled from ASTM, DIN, EN, AMS, and JIS standards.It is designed to help procurement engineers across North America, Europe, Japan, and the Middle East quickly identify the exact equivalent designations for their sourcing documentation and material traceability requirements.

Note: All Jiangsu Liangyi HAYNES HR-160 / UNS N12160 forgings are supplied with EN 10204 3.1 MTC referencing the UNS N12160 and W.Nr. 2.4886 designations simultaneously. If your project needs a specific alternate designation on the MTC, please specify at the time of RFQ.

HAYNES HR-160 High-Temperature Corrosion Resistance: Independent Comparative Analysis

 The choice of HAYNES HR-160 (UNS N12160)  over conventional alternatives is mainly driven by its great performance in mixed corrosive environments — those combining sulfidation, chlorination, and oxidation — where no single conventional heat-resistant alloy can offer the same level of reliability.
The comparative ratings below are based on Jiangsu Liangyi’s more than 25 years of field performance data from installed parts, cross-referenced with published corrosion science literature, to provide an objective, application-specific guide for material selection engineers.

Rating Key: ★★★★★ Outstanding · ★★★★ Excellent · ★★★ Good · ★★ Fair · ★ Poor / Not Recommended

Field note from Jiangsu Liangyi’s project engineering team:In mixed sulfidation + chlorination environments (the primary failure mode in municipal solid waste incinerators and hazardous waste kilns), HAYNES HR‑160 consistently delivers longer service life than Hastelloy C‑276.The reason is that C‑276’s high molybdenum content tends to accelerate the volatilization of molybdenum oxychloride above 700°C — a well‑documented failure mechanism that is effectively suppressed by HR‑160’s silicon‑rich protective oxide layer.This is why our European incineration customers switched from C‑276 to HR‑160, extending their part replacement interval from 14 months to more than 50 months.

Mechanical Properties of HAYNES HR-160 Forged Bars (Solution Annealed)

Our HAYNES HR-160 forged products meet and exceed the industry standard mechanical property requirements in the solution annealed condition, with full batch testing and certification provided for every order. The minimum guaranteed properties are:

• Tensile Strength (σb): ≥ 724 MPa (105 ksi)
• Yield Strength (σ0.2): ≥ 321 MPa (46.5 ksi)
• Elongation (δ): ≥ 66%
• Hardness: ≤ 241 HB (typical in solution annealed condition)

HAYNES HR-160 (UNS N12160) Typical Mechanical Properties at Elevated Temperatures

For most high-temperature applications, relying solely on minimum room-temperature mechanical properties is inadequate for structural design.Engineers need accurate data on how HAYNES HR-160 performs under actual operating temperatures.The table below lists typical (not minimum guaranteed) tensile strength, yield strength, and elongation values across the alloy’s full service temperature range.Data is obtained from elevated-temperature tensile tests conducted on solution‑annealed wrought bar based on ASTM E21 (Standard Test Methods for Elevated Temperature Tension Testing of Metallic Materials). These values are representative of our solution‑annealed forged products and are intended for engineering reference and comparative material selection purposes.

Important design note: The above values represent typical short-term tensile properties.For parts operating above 750°C under continuous loading — such as thermocouple sheaths, radiant tubes, and furnace fixtures — stress‑rupture data and creep allowance calculations are important for safe design.Please contact our engineering team to obtain alloy‑specific creep‑rupture data and design support tailored to your exact temperature and load conditions.

HAYNES HR-160 (UNS N12160) Physical & Thermal Properties — Engineering Constants for Design

Accurate physical and thermal property data is essential for thermal stress analysis, FEA modeling, heat exchanger design, and process piping engineering.The following constants for HAYNES HR-160 (UNS N12160) have been compiled by Jiangsu Liangyi’s metallurgical team from alloy characterization tests and published reference data, and are provided with engineering application notes to support correct design use.All values apply to solution‑annealed material unless otherwise specified.

Manufacturing Process & Heat Treatment Specification

 We control the whole production process of HAYNES HR-160 forgings entirely in‑house — from high‑grade raw material melting, hot forging, heat treatment to final machining and strict quality inspection.This makes sure all parts have consistent, premium quality and improved material performance .

Premium Double Melting Process

 All our raw materials forHAYNES HR-160, UNS N12160, and Alloy HR160  are produced using premium double‑melting processes:either Vacuum Induction Melting + Electro‑Slag Remelting (VIM/ESR) or Vacuum Induction Melting + Vacuum Arc Remelting (VIM/VAR).These advanced melting practices remove harmful non‑metallic inclusions, guarantee tight uniformity in chemical composition, and achieve excellent material purity , which are important factors in realizing the full high‑temperature strength and corrosion resistance of HR‑160 alloy.

Precision Hot Forging Process

We perform hot forging of HAYNES HR-160 using our advanced equipment including a 6300‑ton semi‑automatic hydraulic press, a 4000‑ton hydraulic press, and supporting forging manipulators rated at 70t, 36t, 24t, and 12t.Our forging process keeps strict control over hot working temperature range, deformation rate, and forging reduction ratio to achieve a consistent, fine‑grained internal matrix across the whole part, eliminate internal porosity, and guarantee isotropic mechanical properties.Our forging capacity supports custom single pieces up to 30 tons in weight.

Standard Solution Heat Treatment Specification

To achieve optimum mechanical properties and corrosion resistance, all our HAYNES HR-160 forgings are given standard solution heat treatment in our computer-controlled, atmosphere-protected furnaces:

• Solution Annealing Temperature: 2050°F (1121°C), with sufficient hold time based on section thickness (typically 1 hour per inch of thickness)
• Cooling Method: Rapid quenching (water or polymer quench) to lock in the optimal, corrosion-resistant microstructure
• Intermediate Annealing: For intricate fabrication and forming operations, intermediate annealing can be performed at a minimum temperature of 1950°F (1066°C), followed by rapid cooling

All our HR-160 forgings are supplied in the solution annealed condition, unless custom heat treatment (such as aging) is specified by the customer.

HAYNES HR-160 (UNS N12160) Welding, Joining & Hot/Cold Fabrication Guidelines

 HAYNES HR-160 is generally regarded as weldable using mainstream fusion welding methods.However, due to the alloy’s specific chemical composition — especially its relatively high silicon content — careful attention must be paid to filler metal selection, surface cleanliness, and interpass temperature control to guarantee welds with full corrosion resistance and mechanical integrity.The guidelines below reflect Jiangsu Liangyi’s standard production welding practices for HR‑160 forgings, and are intended to support customers’ welding engineers in developing qualified welding procedures (WPS/PQR) based on ASME Section IX or ISO 15614‑1.

Recommended Filler Metals for HAYNES HR-160 Welding

Pre-Weld Surface Preparation — Zero-Tolerance Contamination Control

Surface contamination is the #1 cause of premature weld failure in HR-160. The following surface preparation protocol must be followed for every weld joint:

• Degrease thoroughly with acetone, MEK, or clean alcohol wipes — remove all oil, cutting fluid, grinding lubricant, and fingerprints within 50mm of the joint line on both sides
• Remove all oxide scale from the weld preparation area by grinding (using dedicated stainless-steel or alumina grinding wheels — never share with carbon steel) or by pickling with ASTM B912-compliant mixed acid solution
• Prohibit contact with sulfur, lead, zinc, or low-melting-point metals (including markers, paints, and zinc-plated fixtures) — these cause liquid metal embrittlement in the HAZ at welding temperatures and are irreversible defects
• Use only dedicated tooling (brushes, clamps, fixtures) that have never been in contact with carbon steel or copper-based alloys, to prevent cross-contamination

Welding Parameters & Interpass Temperature Control

• Preheat: It is not needed.HAYNES HR-160 is not susceptible to hydrogen-induced cold cracking; preheat is counterproductive and increases the risk of sensitization in the HAZ
• Maximum Interpass Temperature: 93°C (200°F). This is a strict limit — exceeding it causes carbide precipitation in the HAZ, reducing ductility and corrosion resistance. Monitor with contact pyrometer between every pass, not just periodically
• Heat Input Control: Use stringer beads (not weave beads) to minimize total heat input and HAZ width. Limit heat input is ≤ 1.5 kJ/mm for GTAW. High heat input accelerates grain growth and increases HAZ sensitization risk
• Back Purging: It is needed for all root passes in pipe and hollow forging welds — use 100% argon back-purging gas to protect the root side from oxidation. Keep a back-purge flow of at least 10 L/min until the root bead is complete and the pipe interior has cooled below 200°C
• Tack Weld Minimum Size: Tack welds must be at least 15mm long to avoid cracking during thermal cycling to full welding temperature. Undersized tacks in high-restraint joints are a common cracking initiation site

Post-Weld Heat Treatment (PWHT)

PWHT is generally not needed for HAYNES HR-160 welds in most corrosive service applications. The as-welded condition typically provides adequate performance if the above welding controls are followed. However, there are two specific situations where PWHT should be considered:

• High-restraint thick-section welds (wall thickness > 75mm): A stress relief at 900°C (1652°F) for 1 hour minimum, followed by air cooling, can reduce residual stress without significantly altering the microstructure. This is not a full solution anneal and does not restore peak corrosion resistance in the HAZ
• Nuclear power applications needing full solution annealing of weld assemblies: A minimum solution anneal at 1121°C (2050°F), followed by rapid quenching, restores the base metal microstructure across both the weld and heat-affected zone (HAZ).This process needs the assembly to resist distortion from full quenching; therefore, part geometry must be evaluated in advance before specifying this heat treatment.

Hot & Cold Forming of HAYNES HR-160 Forged Blanks

• Hot forming temperature range: 980°C – 1200°C (1800°F – 2192°F). Do not hot work below 900°C (1652°F) — below this temperature the alloy becomes increasingly susceptible to surface cracking due to dynamic strain aging
• Cold forming: HR-160 can be cold formed in the annealed condition, but work-hardens significantly faster than austenitic steels. Intermediate anneals (minimum 1066°C / 1950°F, rapid cool) are required when total cold reduction exceeds 15–20% in a single forming sequence
• Machining: HR-160 is machineable but needs sharp tooling, high-pressure coolant, and low cutting speeds compared to austenitic stainless steels. Use carbide or ceramic tooling; avoid dwelling or rubbing cuts that generate work hardening without material removal
