410 martensitic stainless steel bar is made of 1Cr13 (Chinese standard) / SUS410 (JIS standard) material, a high-strength chromium steel.
| Element | Content (%) | Function |
|---|---|---|
| C (Carbon) | ≤0.15 | Provides quench hardenability, increases strength & hardness |
| Cr (Chromium) | 11.5–13.5 | Forms passive film, provides basic corrosion resistance |
| Mn (Manganese) | ≤1.0 | Deoxidizer, enhances strength, excessive content may reduce toughness |
| Si (Silicon) | ≤1.0 | Improves oxidation resistance |
Physical Properties
Density: 7.78 g/cm³ (lighter than 304 austenitic stainless steel, 7.93 g/cm³), suitable for lightweight structures
Melting Point: 1480–1530℃, maintains strength at high temperature, recommended service ≤400℃
Thermal Conductivity: 26 W/(m·K), ~1.7× higher than 304, providing better heat dissipation
Thermal Expansion Coefficient: 10.4×10⁻⁶/℃ (0–100℃), close to carbon steel, compatible for assembly with other metals
Magnetism: Strongly magnetic, suitable for electromagnetic induction components (e.g., solenoid cores)
Mechanical Properties (by Condition)
