60Si2Mn standard:

GB/T 1222-2007

Characteristics and application scope of 60Si2Mn;

It is a widely used silicon-manganese spring steel with good strength, elasticity and hardenability. 55Si2Mn is slightly higher. It is suitable for railway vehicles, automobiles and tractors to make leaf springs or spiral springs with steel wire diameter below 30mm under heavy load, and it is also suitable for working temperature of 250? Heat-resistant spring in non-corrosive medium below℃ and large-scale important spiral spring under alternating load and working under high stress.
