Characteristics and Uses:
60 the strength of steel, the hardness and elasticity are quite high, but the cold deformation of the plastic is low, poor cutting, welding and hardenability are poor, water quenching a tendency to crack, only small parts can be quenched, large multi-By normalizing used to make rollers, shafts, eccentric shaft, coil, cam, spring washers, clutch, rope and other large force in the friction conditions of work, requiring high strength, wear resistance and a certain flexibility of the part
65 steel used to make springs, coil, various gaskets, clutch and shaft manufacturing general machinery, roll, eccentric shaft.
