1. Product Introduction of ASTM A268 TP405
ASTM A268 TP405 (UNS S40500) is a martensitic stainless steel seamless tube designed for medium corrosion resistance and high strength requirements. Through the optimized ratio of low carbon content and chromium elements, TP405 has excellent resistance to stress corrosion cracking while maintaining good formability, and is suitable for high temperature and mild corrosion conditions.
2. Chemical composition of ASTM A268 TP405
| Element | Content Range | Function |
|---|---|---|
| C | ≤0.08 | Control hardness and weldability |
| Cr | 11.5-14.5 | Core element for oxidation and corrosion resistance |
| Mn | ≤1.00 | Deoxidation and hardenability improvement |
| Si | ≤0.50 | Deoxidizer, high temperature strength enhancement |
| P | ≤0.040 | Control impurities (reduce brittleness) |
| S | ≤0.030 | Improve cutting performance |
3. Mechanical properties of ASTM A268 TP405
Tensile strength (Rm): ≥515 MPa
Yield strength (Rp0.2): ≥275 MPa
Elongation (50mm gauge): ≥25%
Hardness (Brinell): ≤241 HB
Note: The strength can be further increased to ≥860 MPa through heat treatment (quenching + tempering) (customization requires clear process)
4. Physical properties of ASTM A268 TP405
| Property | Value |
|---|---|
| Density (20°C) | 7.78 g/cm³ |
| Melting range | 1427-1510°C |
| Coefficient of thermal expansion (20-100°C) | 10.4 μm/m·°C |
| Thermal conductivity (100°C) | 24.9 W/m·K |
| Resistivity (20°C) | 0.60 μΩ·m |
