Spring 60CrMnA Steel

Spring Steel 60CrMnA has higher strength, plasticity and toughness, better hardenability, lower overheating sensitivity than manganese steel, higher than silicon manganese steel, smaller decarburization tendency than silicon manganese steel, and larger tempering brittleness. Therefore, the appropriate tempering temperature and cooling speed should be selected; Generally, Spring Steel 60CrMnA is used in the quenching and medium temperature tempering state for the production of heavy load, large stress and large diameter coil springs in the vehicle and tractor industry

Basic Info

Spring 60CrMnA Steel has high strength and toughness, good hardenability, hot processing performance, good decarburization resistance, overheating sensitivity is lower than manganese spring steel and higher than silicon manganese spring steel, more sensitive to temper brittleness, poor weldability.

It is used as a large spring that works under heavy load and high stress conditions, such as a large section plate spring of automobiles, tractors, and locomotives, and a coil spring with a large diameter.

This standard applies to spring round and square steel (referred to as bar) with a diameter or side length not greater than 100mm, spring flat steel with a thickness not greater than 40mm, spring steel wire with a diameter not greater than 25mm (excluding wire rods for oil quenched and tempered spring steel wire (YB/T 5365)). Rods with diameters or side lengths greater than 100mm, flat steel with thicknesses greater than 40mm and rods with diameters greater than 25mm can also be supplied after negotiation between the supply and demand parties.
