X45CrSi9-3 steel is a martensitic chromium-silicon steel that is widely used in the automotive industry, particularly for internal combustion engine components such as valves. Here is a detailed introduction to X45CrSi9-3 steel:
Chemical Composition
- Carbon (C): 0.40-0.50%
- Silicon (Si): 2.70-3.30%
- Manganese (Mn): Max 0.60%
- Phosphorus (P): Max 0.040%
- Sulfur (S): Max 0.030%
- Chromium (Cr): 8.00-10.0%
- Nickel (Ni): Max 0.50%
Mechanical Properties
- Proof Strength (Rp0.2): 791 MPa (≥)
- Tensile Strength (Rm): 1160 MPa (≥)
- Impact Energy (KV): 44 J
- Elongation at Fracture (A): 43%
- Reduction in Cross Section on Fracture (Z): 31%
- Brinell Hardness (HBW): 134
Heat Treatment
- Annealing: Typically involves heating to a temperature range of 1532°C - 1168°C, followed by slow cooling to achieve a soft and ductile microstructure.
- Quenching: Heating to a temperature of 1191°C, holding for 5-15 minutes, and then air cooling.
- Tempering: After quenching, tempering at 522°C to achieve the desired hardness and toughness.
Applications
X45CrSi9-3 steel is primarily used in the automotive industry for manufacturing components that require high strength and good wear resistance at elevated temperatures. It is particularly suitable for:
- Valve steels for internal combustion engines
- High-temperature components in automotive and industrial applications
Physical Properties
- Melting Temperature: 327.3°C
