65Mn spring steel is a relatively common material in mold production and processing. It is used to make various kinds of flat and round springs of small sizes, cushion springs, spring windings, spring rings, valve springs, clutch springs, brake springs and cold-drawn steel wire cold-coiled helical springs and so on.

High hardness, high strength, 65Mn steel plate strength and hardness than C65 carbon steel.
Good mouldability and toughness, impact resistance and high flexural strength ratio.
High temperature and low temperature resistance
Good abrasion resistance，good corrosion resistance，strong elastic properties
