PRODUCT DETAILS
Product introduction
60Si2Mn spring steel is a widely used silico-manganese spring steel with slightly higher strength, elasticity and hardenability than 55Si2Mn. 60Si2Mn spring steel industry produces flat springs with large load or coil springs with diameter less than 30mm. It is also suitable for making heat-resistant springs with non-corrosive medium with working temperature below 250 °C and with alternating load and high stress. Large important coil springs for working under, as well as automotive shock absorption systems.

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.
