42CrMo4 is a steel for quenching and tempering, which has a good combination of strength and toughness in the quenched and tempered condition. After the oil quenching, the steel will be through hardened up to ø60 mm bar diameter. The microstructure of larger dimensions is not fully martensite. The steel is applicable to induction hardening.
42CrMo4 steel and 42CrMo steel difference WixSteel42CrMo4 is from European standard-EN10083, 42CrMo4 is a kind of alloy steel with high hardenability, good toughness and small deformation during quenching.42CrMo is China GB/T standard grade, it is a medium carbon alloy structural steel with good mechanical properties, good hardenability and
42CrMo4 bars are heated at 845°C followed by quenching in oil. Before hardening, it can be normalized by heating at 913°C for a long period of time followed by air cooling. Forging 42CrMo4 is forged at 926 to 1205°C. Hot Working 42CrMo4 steel can be hot worked at 816 to 1038°C. Cold Working

Low-cycle fatigue properties of steel 42CrMo4 Request PDFThe recommended UTS and elongation values for a typical 42CrMo4 steel are 813 MPa and 12%, respectively. The higher hardness is better to combat low-cycle fatigue and the hardness variation in
Nitriding steels, hardenable alloy steels, carbon steels Gas nitriding can be applied to unalloyed steels and irons to produce a corrosion- and wear-resistant nitride layer. In alloy steels that contain nitride-forming alloy elements (Cr, Mn, Mo, V, W, Al, Ti) a deeper diffusion layer develops.
Through Hardening (Q&T) Through Hardening ("Quench & Temper") is a process used to increase the hardness and tensile strength of material, and in alloy steels such as 4140 and 4340, will result in optimum combinations of strength and toughness.
Through Hardening PauloThrough hardening is the process of using a rapid quench to increase hardness throughout a steel alloy for the purpose of increasing its strength. As opposed to case hardening , which gives steel a hard outer layer while preserving a softer, more ductile core, through hardening diffuses carbon throughout the entire section of steel.
