Martensitic S41500 Stainless Steel Plate – Corrosion Resistant with Superior Mechanical Properties
Introduction
S41500 stainless steel is a low-carbon martensitic alloy engineered to deliver an exceptional combination of high strength, good toughness, and moderate corrosion resistance—making it ideal for demanding engineering applications in power generation, oil & gas, marine, and heavy industry. Unlike conventional martensitic grades (e.g., 410 or 420), S41500 features controlled carbon content and strategic additions of nickel and molybdenum, which significantly enhance weldability, ductility, and resistance to stress corrosion cracking.
Supplied as a wrought plate per ASTM A240/A240M Type 415, S41500 offers mechanical properties far exceeding those of standard stainless steels, while maintaining cost-effectiveness compared to duplex or super austenitic alternatives. At [Your Company Name], we provide certified S41500 stainless steel plates in hot-rolled and forged conditions, with custom cutting, machining, and full traceability to support critical infrastructure projects worldwide.
Why Choose Martensitic S41500?
Martensitic stainless steels are known for their hardness and strength—but often at the expense of toughness and weldability. S41500 breaks this trade-off:
- ✅ High Strength: Tensile strength ≥790 MPa after standard heat treatment
- ✅ Excellent Toughness: Charpy impact energy ≥47 J at –20°C
- ✅ Good Weldability: Low carbon (≤0.06%) minimizes cracking risk
- ✅ Moderate Corrosion Resistance: Performs well in freshwater, steam, and mildly acidic environments
- ✅ Precipitation-Hardenable: Achieves peak properties through simple thermal treatment
These attributes make S41500 a top choice for hydroelectric turbine runners, pump shafts, valve components, and other high-stress parts exposed to dynamic loads and moisture.
Chemical Composition (ASTM A240 Type 415 / UNS S41500)
| Element | Content (%) – Typical Range | ASTM A240 Limit |
|---|---|---|
| Carbon (C) | ≤ 0.06 | Max 0.06 |
| Chromium (Cr) | 11.5 – 14.0 | — |
| Nickel (Ni) | 3.5 – 5.5 | — |
| Molybdenum (Mo) | 0.50 – 1.00 | — |
| Manganese (Mn) | 0.50 – 1.00 | Max 1.00 |
| Silicon (Si) | ≤ 0.60 | Max 0.60 |
| Phosphorus (P) | ≤ 0.030 | Max 0.030 |
| Sulfur (S) | ≤ 0.030 | Max 0.030 |
The addition of Ni and Mo refines the microstructure, improves hardenability, and boosts resistance to pitting in chloride-containing environments.
Mechanical Properties (After Heat Treatment – H1025 Condition)
| Property | Minimum Value |
|---|---|
| Tensile Strength | 790 MPa (115 ksi) |
| Yield Strength (0.2% offset) | 620 MPa (90 ksi) |
| Elongation | ≥ 15% |
| Reduction of Area | ≥ 45% |
| Hardness | 28–34 HRC |
| Charpy V-Notch Impact (–20°C) | ≥ 47 J (35 ft·lbf) |
Note: Heat treatment is essential to achieve these properties. Common tempers include:
- H1025: Standard for turbine applications (550°C/1025°F aging)
- H1150D: Dual tempering for maximum toughness in low-temperature or sour service
Corrosion Resistance Performance
While not as corrosion-resistant as 316L or duplex grades, S41500 offers superior performance over basic martensitic steels:
- ✅ Freshwater & Steam: Excellent long-term stability—ideal for hydro turbines
- ✅ Mild Acids & Alkalis: Suitable for chemical processing equipment
- ✅ Atmospheric Exposure: Resists rusting better than carbon steel
- ⚠️ Seawater/High Chlorides: Not recommended without protective coating
Its chromium-rich passive layer, enhanced by molybdenum, provides effective protection against general and localized corrosion in non-aggressive environments.

Frequently Asked Questions (FAQ)
Q: Is S41500 magnetic?
A: Yes—it’s martensitic and therefore ferromagnetic, which can be advantageous for certain sensors or lifting applications.
A: Yes—it’s martensitic and therefore ferromagnetic, which can be advantageous for certain sensors or lifting applications.
Q: Can it be used without heat treatment?
A: Not recommended. As-rolled S41500 lacks required strength and toughness. Heat treatment (e.g., H1025) is mandatory for structural use.
