(6) Application:

60Si2Mn is widely spring steel, strength, elasticity and 55Si2Mn slightly higher than its quench-hardening ability. Suitable for railway vehicle and automobile tractor industry producing under large load oblate spring or line diameter in the spiral spring under 30mm

 is mainly has good flexibility, and because it is in dynamic loading environment under the working conditions, so for manufacturing spring material the main due to high yield strength, In under heavy load does not cause plastic deformation, Due to high fatigue strength, the loading under the action of repeated with long service life; And have enough toughness and plasticity, in order to avoid wallop under the action of suddenly brittle fracture
