Factory OEM Anti-Heat High Temperature Cr5 Alloy Springs

factory OEM anti-heat high temperature CR5 alloy springs

Oil-tempered springs are made of high carbon steel wires, which are filtered through a sequence of dies until the proper thickness and shape are achieved. The spring is then run through a series of heating cycles that are tempered with oil until the desired tension is reached. The end result is a spring that's strong, flexible, and durable.
