AISI 440C Martensitic Stainless Steel: Technical Profile
Core Composition & Properties
| Characteristic | Specification |
|---|---|
| Key Elements | C (0.95-1.20%), Cr (17-19%), Ni/Mo (trace) |
| Physical | Density: 7.78 g/cm³ |
| Mechanical (HT) | Tensile: ≥880 MPa |
| Corrosion | Chromium oxide layer resists atmospheric/chemical corrosion |
Critical Processing
Heat Treatment:
- Quenching: Forms martensitic structure (> critical temp)
- Tempering: Enhances toughness/stress relief (sub-critical temp)
Delivery: Supplied heat-treated or as-processed per requirement
