Heat Treatment Specification & Pitting Resistance Equivalent (PREN) of 1.4563
Standard Heat Treatment Process for 1.4563 Forgings
Unless otherwise specified by the customer, all 1.4563 (X1NiCrMoCu31-27-4) forgings supplied by Jiangsu Liangyi are delivered in the solution-annealed and water-quenched condition.This process dissolves all precipitated phases, including sigma phase and carbides, and creates a fully austenitic, uniform microstructure that maximizes corrosion resistance and toughness.The specific heat treatment parameters we use are:
Pitting Resistance Equivalent Number (PREN) of 1.4563
The Pitting Resistance Equivalent Number (PREN) is the standard measure used in the stainless steel and corrosion engineering industry to compare how well a material resists local pitting corrosion in environments with chloride.The formula used for austenitic stainless steels is:
PREN = %Cr + 3.3 × %Mo + 16 × %N
Based on the typical composition of 1.4563 (Cr = 27%, Mo = 3.5%), its calculated PREN value is about 38.6 to 44, depending on the actual chemical analysis of each heat.This range puts 1.4563 in the top class of corrosion-resistant alloys, performing significantly better than standard austenitic stainless steels and most duplex stainless steels.The visual comparison below shows this more clearly:
Note: PREN values are calculated from nominal composition midpoints. Actual values vary by heat analysis. Higher PREN indicates greater pitting resistance in chloride environments.
However, what PREN does not reflect — and where 1.4563 has a clear advantage over 254 SMO and duplex alloys — is its performance in reducing acid environments.
The high copper content (0.6–1.4%) in 1.4563 greatly inhibits active corrosion in sulfuric acid, phosphoric acid, and similar media.No other widely used wrought alloy in the same PREN range offers this unique combination of properties.
Corrosion Performance Data for 1.4563 Forged Steel
Choosing a material only based on its nominal composition and PREN value can leave hidden performance gaps that matter in real-world use.The data below covers the main corrosion behaviors most important to the industries we serve.All reference values are in line with published technical literature and testing carried out according to ASTM and ISO standards.
Critical Pitting Temperature (CPT) — ASTM G48 Method A
The Critical Pitting Temperature (CPT) is measured by immersing a test coupon in a 6% FeCl₃ solution (ASTM G48 Method A) and recording the lowest temperature at which pitting starts within 72 hours.CPT serves as a practical material selection standard for equipment used in hot chloride-containing process fluids, seawater, or cooling water.
| Grade | CPT (°C, typical) | Practical Implication |
|---|---|---|
| 316L (1.4404) | 0 – 15 °C | Not suitable for hot chloride service |
| 904L (1.4539) | 30 – 40 °C | Moderate chloride resistance |
| SAF 2507 duplex (1.4410) | 55 – 70 °C | High pitting resistance; limited in reducing acids |
| 254 SMO (1.4547) | 60 – 75 °C | Excellent chloride resistance |
| 1.4563 / Alloy 31 (X1NiCrMoCu31-27-4) | ≥ 60 °C | Excellent pitting resistance + superior reducing acid resistance |
Sulfuric Acid Corrosion Resistance
Resistance to sulfuric acid (H₂SO₄) is one of the main reasons 1.4563 is chosen over 254 SMO and high‑PREN duplex grades in chemical processing.With 0.6–1.4 wt.% copper, 1.4563 forms a protective passive layer in non‑oxidizing acids, greatly lowering corrosion rates at concentrations where even 904L suffers significant attack.
| Test Condition | 316L | 904L | 1.4563 / Alloy 31 |
|---|---|---|---|
| 10% H₂SO₄, 25 °C | High attack (> 1 mm/year) | < 0.5 mm/year | < 0.1 mm/year |
| 30% H₂SO₄, 60 °C | Severe (> 5 mm/year) | Moderate (0.5–2 mm/year) | < 0.3 mm/year |
| 50% H₂SO₄, 25 °C | Not suitable | < 0.5 mm/year | < 0.1 mm/year |
Sour Service Performance — NACE MR0175/ISO 15156 Compliance
1.4563 (X1NiCrMoCu31-27-4) is listed as an acceptable material for sour oil and gas service under NACE MR0175/ISO 15156-3, provided the following conditions are maintained in the supplied forgings:

1.4563 (Alloy 31) vs. Alternative Grades — Technical Comparison
Choosing a corrosion-resistant alloy for a specific application needs evaluating multiple material properties at the same time.Price alone never determines the right grade — total cost of ownership, replacement frequency, and compliance requirements are equally important factors.The table below helps engineers and procurement teams make an objective comparison between 1.4563 and the alloys it most often competes with or replaces.
| Property / Criterion | 316L (1.4404) | 904L (1.4539) | 254 SMO (1.4547) | SAF 2507 Duplex (1.4410) | 1.4563 / Alloy 31 |
|---|---|---|---|---|---|
| Ni content (wt.%) | 10–14 | 23–28 | 17–22 | 6–8 | 30–34 |
| Cr content (wt.%) | 16–18 | 19–23 | 19–21 | 24–26 | 26–28 |
| Mo content (wt.%) | 2–3 | 4–5 | 6–7 | 3–5 | 3–4 |
| Cu content (wt.%) | — | 1–2 | 0.5–1 | — | 0.6–1.4 |
| PREN (approximate) | ~24 | ~32 | ~43 | ~42 | ~38–44 |
| Pitting resistance (Cl⁻) | Low | Moderate | Excellent | Excellent | Excellent |
| Resistance to reducing acids (H₂SO₄, H₃PO₄) | Poor | Good | Limited (no Cu) | Limited (no Cu) | Superior (high Cu + Ni) |
| SCC resistance in Cl⁻ | Poor | Good | Good | Good | Excellent |
| Low-temperature toughness (−196 °C) | Good | Good | Good | Limited (brittle duplex) | Excellent (≥ 60 J at −196 °C) |
| NACE MR0175 sour service | Conditional only | Yes (with limits) | Yes | Yes | Yes — fully compliant |
| Microstructure | Austenitic | Austenitic | Austenitic | Duplex (α+γ) | Fully austenitic |
| Weldability (for assemblies) | Excellent | Excellent | Good | Moderate | Excellent |
| Relative material cost tier | Low | Medium | Medium–High | Medium–High | Medium–High |
When to Specify 1.4563 Over Other Grades
- Replace 316L or 317L when equipment suffers repeated pitting, SCC, or premature failure in chloride or acidic service — 1.4563 has a step-change improvement
- Replace or upgrade from 904L when the process stream contains moderate-to-high chloride concentrations or strong reducing acids — 1.4563 has superior pitting resistance and better reducing-acid performance at comparable cost
- Prefer 1.4563 over 254 SMO for applications involving sulfuric acid, phosphoric acid, or vinyl chloride — the additional copper content gives 1.4563 a decisive corrosion rate advantage in these media
- Prefer 1.4563 over SAF 2507 duplex for cryogenic service (below −50 °C), where duplex microstructures lose impact toughness, and for reducing acid environments where the duplex phase structure has no copper-equivalent benefit
- 1.4563 is the correct first choice when a single alloy must perform reliably across sour gas (NACE MR0175), oxidising chloride media, reducing acids, and low-temperature service simultaneously

We offer three melting routes depending on application requirements: (1) Standard EAF + LF + VOD — suitable for most industrial and oil & gas applications; (2) Double melted: VIM + VAR — for improved cleanliness and homogeneity in demanding chemical, nuclear, or aerospace applications; (3) Triple melted: VIM + ESR + VAR — for the most important applications needing maximum material purity, such as nuclear components, subsea downhole tools, and aerospace parts. All melt routes are supplied with full traceability documentation.
How does 1.4563 perform in sulfuric acid compared to 904L and 316L?
1.4563 performs much better than both 904L and 316L when exposed to sulfuric acid. In a 10% sulfuric acid (H₂SO₄) solution at 25 °C, 316L has a corrosion rate of more than 1 mm per year, so it is not suitable for use in this environment. 904L works better, but in concentrated or high-temperature acid, its corrosion rate still ranges from 0.1 to 0.5 mm per year. By comparison, 1.4563 has a corrosion rate of less than 0.1 mm per year in 10% sulfuric acid at 25 °C, and less than 0.3 mm per year in 30% sulfuric acid at 60 °C. This advantage mainly comes from its copper content (0.6–1.4%) and high nickel content; together, these two elements form a protective layer on the alloy’s surface in reducing acidic environments, while other materials still corrode easily.
Do you support third-party inspection (TPI) and witness testing?
Yes. We regularly allow third-party inspection at our Jiangyin factory by accredited agencies such as BV (Bureau Veritas), SGS, TÜV, and Intertek. We can provide EN 10204 3.2 certificates, which needs the 3.2 inspector to witness the tests and sign the test records.You are also welcome to send your representatives to attend the witness testing in person. For important orders, we can agree on inspection hold points and release procedures in a pre-production Quality Plan (QP).
