Product Description
Sk7 spring steel
SK7 is silicomanganese spring steel 55Si2Mn slightly higher. The utility model is suitable for manufacturing heat-resistant springs in non-corrosive medium with coil spring of 250 ° C and flat spring of 30 mm and less than 250 ° C, which bear larger load, in the industry of railway vehicles, automobiles and tractors. And a large and important coil spring which can bear alternating load and work under high stress. Also suitable for the production of working temperature or diameter in line, strength, elasticity and hardenability.
