En 41cr4 Steel Properties After Quenching And Tempering - China

EN 41Cr4 steel performance after quenching and tempering Mechanical properties: After quenching and tempering, the tensile strength of EN 41Cr4 steel is generally between 800MPa and 1200MPa, the yield strength is between 600MPa and 800MPa, the elongation is between 10% and 15%, and the impact toughness can reach 20~30J/cm².

These performance indicators enable it to withstand large tensile, compressive and impact loads.

Wear resistance: After quenching and tempering, 40Cr alloy steel has certain wear resistance, but its wear resistance is not as good as that of steel after surface hardening.

In some occasions where higher wear resistance is required, its wear resistance can be further improved by subsequent treatments such as surface quenching.

Fatigue performance: Due to the good toughness and strength of EN 41Cr4 steel after quenching and tempering, its fatigue performance is also good.

Under the action of alternating loads, it can withstand more cycles without fatigue fracture, and is suitable for manufacturing parts that withstand fatigue loads, such as shafts, gears, etc.
