Carbon Steel Spring Wire

55SiCrA/ SAE 9254 3mm Carbon Steel Wire For Flat /Spiral Spring

55SiCrA/ SAE 9254 3mm Carbon Steel Wire For Flat /Spiral Spring

55SiCrA is suitable for the manufacture of flat springs or spiral springs with wire diameters of less than 30mm in the railway vehicle and automotive tractor industries subjected to large loads, as well as heat-resistant springs in non-corrosive media with working temperatures below 250°C and small round bars for large and important spiral springs subjected to alternating loads and working under high stress.

55SiCrA/ SAE 9254 3mm Carbon Steel Wire For Flat /Spiral Spring


55SiCrA is a widely used silicon manganese spring steel, strength, elasticity and hardenability than 55Si2Mn slightly higher. 55SiCrA is suitable for railway vehicles, automobile tractor industry to produce flat springs or wire diameter of 30mm below the spiral spring, also suitable for the production of non-corrosive media in the working temperature below 250 heat-resistant springs and bear alternating loads and work under high stress in the large important coil spring.
