Corrosion Performance in Common Industrial Media
Unlike generic "good corrosion resistance" claims found on most datasheets, the table below provides environment-specific performance ratings based on our customers' long-term field feedback across 20+ years of 2.4816 forging supply. Ratings reflect typical behaviour at moderate concentrations and temperatures; always confirm with your corrosion engineer for specific process conditions.
| Corrosive Medium | Concentration / Temp | 2.4816 Performance | Corrosion Rate (mm/year) | Notes |
|---|---|---|---|---|
| Caustic (NaOH) | 50%, up to 120°C | ■ Excellent | < 0.025 | Superior to 316L in hot caustic; preferred in paper mill digesters |

Welding & Fabrication Guide for 2.4816 NiCr15Fe NiCr15Fe8 Forgings
One of the practical advantages of 2.4816 over many precipitation-hardened nickel alloys is its excellent weldability. It does not need pre-weld heat treatment in most applications, and the risk of heat-affected zone (HAZ) cracking is low when correct procedures are followed. The guidance below is based on our engineering team's accumulated experience supporting customers through weld qualification of 2.4816 forgings.
Recommended Welding Consumables
| Welding Process | Filler Metal / Electrode | AWS / EN Classification | Notes |
|---|---|---|---|
| TIG / GTAW | ERNiCr-3 | AWS A5.14 | Most common; excellent for precision root passes and thin-wall tube sheets |
| MIG / GMAW | ERNiCr-3 | AWS A5.14 | Suitable for thick-section weld filling; use spray or pulsed transfer mode |
| SMAW (Stick) | ENiCrFe-3 | AWS A5.11 | For site welding and repair; lower deposition quality than TIG — confirm with EPC/owner for nuclear apps |
| SAW (Submerged Arc) | ERNiCr-3 wire + matching flux | AWS A5.14 | Used for heavy-section tube sheet cladding and weld overlay; confirm flux composition is NiCr-compatible |
| Dissimilar joint to carbon steel | ERNiCrMo-3 (Alloy 625-type) | AWS A5.14 | Higher Mo content buffers dilution effects at the fusion line; preferred over ERNiCr-3 for CS/NiCr15Fe joints |
Preheat, Interpass Temperature & Post-Weld Treatment
- Preheat: Not needed for section thickness ≤ 25 mm at ambient temperature above 10°C. For sections > 25 mm or temperatures below 5°C, preheat to 50–80°C to prevent moisture-induced porosity.
- Maximum Interpass Temperature: 150°C. Exceeding this may cause grain boundary carbide precipitation (sensitization) which reduces corrosion resistance in aggressive media.
- Post-Weld Annealing (PWHT): It is generally not needed for structural joints. For nuclear-specification applications and for joints that will see hot caustic or high-temperature oxidizing service, post-weld annealing at 900–980°C followed by rapid air or water quench is recommended to restore full corrosion resistance.
- Stress Relief: Stress relief at sub-sensitizing temperatures (400–600°C) is not recommended — it can trigger carbide precipitation without fully relieving weld stresses. Either full anneal or leave as-welded.
When to Choose 2.4816 vs Alternative Alloys — Engineering Decision Guide
Choosing the wrong nickel alloy for a forging project is one of the most expensive mistakes in process equipment engineering — either through premature failure or unnecessary overspend on a premium alloy when 2.4816 was perfectly adequate. Based on thousands of enquiries we have processed over 25 years, the following guide reflects the most common decision scenarios we see in the field.
Temperature Range vs Alloy Selection
- If environment is non-oxidizing and chloride-free, austenitic SS may be sufficient
- Cost advantage: 316L is 4–6× cheaper than 2.4816
- Switch to 2.4816 if: SCC risk is present, caustic concentration > 30%, or high cyclic thermal loading
- Optimal balance of oxidation resistance, creep strength and cost
- Superior to 304/316 which suffers sigma phase embrittlement above 500°C
- Better SCC resistance than duplex SS in this range
- Nuclear parts, heat exchangers, valve bodies: first choice
- Above 800°C, grain growth in 2.4816 accelerates under cyclic loading
- For sustained >900°C: consider Inconel® 625 (2.4856) or Alloy 602CA (2.4633)
- Exception: furnace fixtures under non-stress-bearing loads can use 2.4816 up to 1000°C
Corrosive Environment vs Alloy Selection
- Hot caustic (NaOH) > 30%, any temperature
- Oxidizing/carburizing atmosphere < 1000°C
- Sour gas (H₂S/CO₂) — NACE MR0175 service
- Dilute acids at moderate temperatures
- Nuclear radiation environment
- Chloride SCC risk (replaces 304/316 SS)
- Seawater immersion with high flow velocity (erosion-corrosion)
- Subsea or offshore environments > 3 years service
- High-strength requirement (>690 MPa Rm) at moderate temperature
- Mixed acid environments with variable Cl⁻ content
- Concentrated HCl (>5%) at any temperature
- Hot concentrated H₂SO₄ or mixed acid environments
- Wet chlorine or chlorinated solvents
- Strong reducing acids with oxidizing impurities
Advanced Triple Melt Manufacturing Process for 2.4816 NiCr15Fe NiCr15Fe8 Forgings in China
At our Jiangyin factory, we use state-of-the-art manufacturing processes to produce high-quality 2.4816 forged parts that exceed industry standards. Our full in-house production chain allows us to control every step from raw material to finished product.
Premium Triple Melt Process
All our NiCr15Fe forgings are produced in a rigorous triple melt process. That guarantees great material purity and homogeneity, which is important for nuclear power and aerospace applications:
- Vacuum Induction Melting (VIM): Removes impurities and controls chemical composition precisely to ±0.1% on all major elements
- Electroslag Remelting (ESR): Refines the grain matrix, removes sulfide and oxide inclusions, and improves mechanical properties
- Vacuum Arc Remelting (VAR): Deletes macro-segregation and internal shrinkage porosity; ensures the ingot cross-section has < 5 mm maximum inclusion size, verifiable by ultrasonic billet inspection
Precision Forging & Heat Treatment
We use 2000-6300 ton hydraulic presses and 1-5 meter seamless rolling machines to forge 2.4816 parts to near-net shape, reducing material waste and machining costs. Our heat treatment process is carefully controlled to achieve the desired mechanical properties, compliant with ASTM A370 standards:
- Annealing: 871–982°C (1600–1800°F) for 10–15 minutes per 25 mm of section thickness (minimum 30 minutes)
- Cooling: Water quenching preferred for maximum grain boundary cleanliness; air cooling acceptable for non-corrosive service applications
- All heat treatment furnaces are equipped with calibrated thermocouples and temperature recorders; furnace temperature uniformity records are available as part of our standard production file
- Custom heat treatment available to meet specific project requirements, including customer-witnessed thermal cycles
CNC Machining & Finishing
We offer complete in-house CNC machining services to deliver finished parts ready for assembly. We can turn up to 6,000 mm in diameter, mill, drill, gun-drill (deep holes), grind, and treat surfaces. The roughness of the surface can be anywhere from Ra 0.8 to 6.3 µm, depending on the type of machining.

Industrial Applications & Typical Project Examples of 2.4816 NiCr15Fe NiCr15Fe8 Forgings
NiCr15Fe8 forgings from Jiangsu China are widely used in industries that require components to withstand high temperatures, high pressures and corrosive environments. The project examples below are illustrative of the type of work we regularly undertake — they represent the typical specifications, challenges and solutions encountered in our daily production. For reference to specific completed projects, please visit our Reference page or contact our sales team.
Steam Generator Component Rings — PWR Plant Specification Example
Nuclear steam generator parts frequently require tight UT acceptance criteria (tighter than standard commercial ASTM A388 levels), confirmed chemical composition by OES on every heat, and EN10204 3.2 MTCs witnessed by a customer-nominated or owner-approved third-party inspector. Dimensional tolerances are typically ±0.5–1.0 mm on rough-turned OD/ID and face.
For nuclear-specification enquiries, we recommend customers specify all acceptance criteria explicitly in their RFQ — UT acceptance level (FBH equivalent size), MTC level (3.1 or 3.2), TPI body preference, and any project-specific documentation requirements. We then confirm compliance item by item in our technical quotation so there are no surprises at inspection. Customers should note that formal nuclear code qualification (RCC-M, ASME NQA-1, HAF 604) is granted by the nuclear plant owner or EPC — not by the forging supplier — and we encourage customers to confirm their specific qualification chain requirements.
Wellhead & Christmas Tree Valve Body Forgings — Sour Service Specification
Carbon steel and austenitic stainless steels (304/316) are susceptible to sulfide stress cracking (SSC) and CO₂ corrosion in environments containing H₂S. 2.4816 (NiCr15Fe8) with its ≥72% nickel content is highly resistant to SSC and complies with NACE MR0175 / ISO 15156 hardness requirements (typically 78–90 HRB in the annealed condition, well within the ≤ 35 HRC limit). This makes it a cost-effective upgrade for wellhead parts in sour gas fields compared to more expensive Alloy 625 (2.4856), provided the application does not require the higher strength or pitting resistance that molybdenum provides.
API 6A orders typically include: EN10204 3.1 MTC with full chemistry and mechanical results; 100% UT per API 6A Appendix D; hardness mapping (minimum 3 locations per part); dimensional report; and a material compliance statement referencing NACE MR0175. PSL-2 and PSL-3 documentation packages available upon specification.
Heat Exchanger Tube Sheets — Hot Caustic (NaOH) Service
Nickel is one of the few structural metals with inherent resistance to all concentrations of hot sodium hydroxide (NaOH). Titanium — often considered a corrosion-resistant alternative — is in fact susceptible to pitting and SCC in hot concentrated caustic above 80°C. Duplex and austenitic stainless steels suffer SCC in NaOH above approximately 50% concentration. 2.4816's ≥72% nickel base makes it the industry-standard choice for chlor-alkali plants, paper mill digesters and chemical evaporators in hot caustic service.
For tube sheet applications, customers should specify: final OD and thickness with tolerances; tube hole pattern and positional tolerance (we supply rough blanks; tube drilling is typically done by the heat exchanger fabricator); surface condition required (as-forged face, rough-turned or machined); and whether IGC testing (ASTM A262 Practice C) is required after final machining. We can arrange IGC testing via accredited partner laboratory — please include this in your RFQ.
