The strength, hardness, elasticity and hardenability of 65Mn steel are much better than ordinary steel.It has overheat sensitivity and temper brittleness tendency, and water quenching has crack tendency.The annealed state has good machinability, low cold deformation plasticity and poor weldability.The surface decarburization tendency is smaller than that of silicon steel.

Characteristics: commonly used spring steel, the final heat treatment for quenching, tempering.This steel has higher strength, greater hardenability, less tendency to decarburize, but it is sensitive to overheating, easy to appear quenching crack, and tempering hardenability.Under the condition of annealing, the machinability is good, the weldability is good, the cold deformation plasticity is low, the strip can be general bending forming processing.
Application: As a small size of all kinds of flat, round spring, cushion spring, spring spring, can also make spring ring, valve spring, clutch reeds, brake springs and cold drawn steel wire cold coil coil spring.

*Storage: Pay attention to moisture, dust, oil, lubricating oil, as well as surface rust, or poor welding corrosion resistance.When water is immersed between the film and the steel substrate, the corrosion rate is faster than that without the film.Warehouse storage should be placed in a clean, dry and easy to open the air, to maintain the original packaging state, the stainless steel film should avoid direct light, film should be periodic inspection, if the film deterioration (film life of 6 months) should be replaced immediately, if the packing material when pad paper, in order to prevent surface corrosion should be immediately removed pad paper.
