Martensitic stainless steel is a high-carbon, magnetic alloy known for its exceptional hardness, strength, and moderate corrosion resistance. Unlike austenitic (e.g., 304) or ferritic (e.g., 430) stainless steels, martensitic grades can be heat-treated to achieve extreme hardness (up to 60 HRC), making them ideal for cutting tools, surgical instruments, and industrial machinery.

Composition & Grades of Martensitic Stainless Steel
| Grade | Carbon (C) | Chromium (Cr) | Nickel (Ni) | Molybdenum (Mo) | Hardness (HRC) |
|---|---|---|---|---|---|
| 410 | 0.08–0.15% | 11.5–13.5% | ≤1% | – | 40–45 (heat-treated) |
| 420 | 0.15–0.40% | 12–14% | ≤1% | – | 50–55 (heat-treated) |
| 440C | 0.95–1.20% | 16–18% | ≤0.75% | ≤0.75% | 55–60 (heat-treated) |
Key Benefits:
✔ High Hardness & Wear Resistance – Ideal for blades, bearings, and turbine components.
✔ Heat-Treatable – Can be hardened via quenching & tempering for customized strength.
✔ Moderate Corrosion Resistance – Better than carbon steel but less than 316 stainless.
✔ Magnetic Properties – Suitable for electromagnetic applications.
✔ Cost-Effective Alternative – More affordable than tool steels with similar performance.
