60si2mna spring steel60si2mna standard:gb/t 1222-2007
60Si2mna characteristics and scope of application:It is a widely used silicon-manganese spring steel with slightly higher strength, elasticity and hardenability than 55si2mn. It is suitable for the production of flat springs with large loads or coil springs with a wire diameter of less than 30mm in the railway vehicle and automobile tractor industry, and is also suitable for the production of heat-resistant springs in non-corrosive media with a working temperature of less than 250 and large and important coiled springs that bear alternating loads and work under high stress.

That's pretty much it, but it depends on how well you quench. The principles of temperature selection are: 1. The lower limit of tempering should be taken to pursue a high elastic limit; 2. The lower limit temperature should be taken for the surface ***, and the upper limit temperature should be taken otherwise.
