42CrMo4 steel plate is an improvement of American AISI standard 4140 steel. 42CrMo4 steel plate has good machinability, easy polishing, easy to bite, can be used for electroplating, high strength, high hardenability, good toughness, small deformation when quenching, high creep strength and durable strength at high temperature.
42CrMo4 steel plate is used to manufacture forgings that require higher strength and larger quenching section than 34CrMo4 steel, such as big gear for locomotive traction, turbocharger transmission gear, rear axle, connecting rod and spring clamp under great load. 42CrMo4 steel plate can also be used for drilling pipe joints and fishing tools in deep oil Wells below 2000m.
42CrMo4 steel plate delivery status: Delivered in heat treated (normalizing, annealing or high temperature tempering) or without heat treatment. The delivery status shall be specified in the contract.
42CrMo4 steel plate softening annealing specification: annealing temperature 680-700℃, slow cooling in furnace, hardness 217HBW.
