AISI4140 42CrMo4 Alloy Steel muaj cov tshuab ua tau zoo, kev ua haujlwm me me deformation, cov rog tsis kam ua haujlwm zoo, nruab nrab thiab hais txog Hardenability steel. Tom qab 4140 kho cov cua sov, nws muaj lub zog zoo thiab cov cuab yeej zoo txhua yam, kev ua haujlwm zoo, muab siab. Kev pab ntau tshaj plaws sov siab yog 427 ℃. 4140 muaj lub zog siab, ua haujlwm siab, zoo toughness, me deformation thaum quenching, nkag siab lub zog thiab kev tiv thaiv siab ntawm qhov kub. Nws tuaj yeem siv los tsim kev zam txim nrog lub zog siab dua thiab loj dua quenching thiab tempering seem ntau dua li 35CrMo steel, xws li lub zog loj rau lub tshuab tsheb ciav hlau, kis lub iav rau supercharger, qag rov qab, txuas pas nrig thiab lub caij nplooj ntoos hlav clamp nrog rau cov peev xwm loj, laum yeeb sib koom thiab nuv ntses twj rau roj sib sib zog nqus dej hauv qab 2000m, thiab tuag rau lub tshuab khoov, thiab lwm yam.
