Heat treatment method

60Si2Mn heat treatment methods are isothermal tempering and grading quenching, sub-temperature quenching and high temperature tempering, deformation heat treatment process. The method can effectively improve the strength and service life of 60Si2Mn spring steel. 60Si2Mn belongs to spring steel, suitable for making automobile leaf spring. 60Si2Mn spring steel heat treatment isothermal tempering and grading quenching, sub-temperature quenching and high temperature tempering, deformation heat treatment process. The method can effectively improve the strength and service life of 60Si2Mn spring steel.

density

60Si2Mn density of 7.85g / cm3. 60Si2Mn is widely used silicon manganese spring steel, strength, elasticity and hardenability than 55Si2Mn slightly higher. Suitable for railway vehicles, automobile tractor industry to produce a larger load of flat springs or wire diameter of 30mm below the coil spring.
