Our specialized casting expertise combines material science excellence with advanced foundry technologies to produce durable, heat-resistant components that withstand extreme operating conditions while maintaining structural integrity.

Material Properties and Advantages

Stainless Steel 304 (UNS S30400) offers superior characteristics for turbocharger applications:

• Excellent high-temperature strength maintaining 80% yield strength at 500°C

• Outstanding oxidation resistance up to 870°C continuous service

• Tensile strength: 505 MPa minimum at room temperature

• Yield strength: 215 MPa minimum

• Elongation: 40% minimum in 2 inches

• Thermal expansion coefficient: 17.2 μm/m·°C (20-100°C)
  The material's chromium-nickel composition (18-20% Cr, 8-10.5% Ni) provides exceptional corrosion resistance against exhaust gases and environmental contaminants, while its austenitic structure ensures good fatigue resistance under thermal cycling conditions.
