42crmo4

Medium carbon chromium-molybdenum alloy steel SCM440, an alloy steel containing chromium and molybdenum. It has the advantages of stable composition, low harmful elements, high steel purity, small decarburization layer, and few surface defects. Easy to spheroidize and has low cold cracking rate. Alloy steel SCM440 is usually hardened and tempered. The ultimate tensile strength is 850-1000Mpa. This material strikes a very good balance between strength, toughness and wear resistance. The alloy's chromium content provides good hardness penetration, while the molybdenum element imparts average hardness and high strength. Alloy steel SCM440 responds well to heat treatment and is easy to process under heat treatment conditions. This material offers many desirable properties such as good strength and wear resistance, excellent toughness, good ductility and resistance to high temperature stress.Our company can provide SCM440 hot-rolled or forged materials, etc.

42CrMo4 steel has high strength, hardenability, good toughness, small deformation during quenching, and high creep strength and durable strength at high temperatures. 42CrMo4 steel is an improved variety of American AISI standard 4140 steel. The steel has good machinability, is easy to polish, is easy to scratch, and can be electroplated
