Steel constructional spring-spring

Steel constructional spring-spring – is steel for springs with a carbon content of 0.5-0.75%. This steel type additionally alloyed with silicon (up to 2.8%), manganese (up to 1.2%), chromium (up to 1.2%), vanadium (up to 0.25%), tungsten (up to 1.2%) and nickel (up to 1.7%).In this case, the grain is grind. This helps to increase the steel resistance to small plastic deformations and increase its relaxation stability.
