Procurement Of Reliable Astm 5140 Material Performance Advantages - China

ASTM 5140 material is a medium-carbon chromium alloy steel, corresponding to China's GB standard 40Cr and Germany's DIN standard 41Cr4 - It is a widely used quenched and tempered steel.

High Strength: The addition of chromium (Cr) significantly improves the steel's hardenability, resulting in a uniform, high-strength martensite structure across the entire cross-section of parts during quenching.

After quenching and tempering, it exhibits high tensile strength (≥980 MPa) and yield strength (≥785 MPa).

Good Toughness: After quenching, ASTM 5140 material undergoes high-temperature tempering (typically 500-600°C), transforming the unstable martensite into a strong and highly ductile **tempered bainite** structure.

This ensures that while maintaining high strength, it also possesses sufficient ductility and toughness (elongation ≥12%) to withstand impact loads and avoid brittle fracture.

Conclusion: This "strong and tough" combination of ASTM 5140 material makes it ideal for manufacturing parts subjected to complex stresses, such as simultaneous bending, torsion, and impact.
