6150 is a kind of higher spring, which is used as a high load important spring with large section and valve spring, piston spring and safety valve spring with working temperature<300 ℃.Spring steel is a name given to a wide range of steels used in the manufacture of springs, prominently in automotive and industrial suspension applications. These steels are generally low-alloy manganese, medium-carbon steel or high-carbon steel with a very high yield strength.
