60Si2Mn Spring Steel Round Bar 50mm 60mm 80mm 90mm 9260
60Si2Mn Spring Steel Round Bar 9260 6.0mm-1200mm
60Si2Mn spring steel is a widely used silicon manganese spring steel with slightly higher strength, elasticity, and hardenability than 55Si2Mn. 60Si2Mn spring steel is used in the industry to produce flat springs that can withstand large loads or spiral springs with a wire diameter of less than 30mm. It is also suitable for producing heat resistant springs in non corrosive media with a working temperature of less than 250 ℃, as well as large and important coil springs that can withstand alternating loads and work under high stress, as well as automotive shock absorption systems.
