SUMMARY
The cyclic fatigue properties of Chinese steel 30Mn2 are critical for performing fatigue life analysis on components such as truck spindles. The chemical composition of 30Mn2 includes 0.27-0.34% Carbon, 0.17-0.371% Silicon, and 1.40-1.80% Manganese, as per the Chinese National Standard GBT3077-1999. Mechanical properties after heat treatment indicate a tensile strength of 785 MPa and a yield strength of 635 MPa, with an elongation after fracture of 12% and a hardness rating of <=207 HB10/3000. These properties are essential for engineers and designers working with this material.
