1) 42CrMo iav steel muaj cov yam ntxwv ntawm lub zog siab, siab tawv-muaj peev xwm, zoo toughness, me me deformation thaum lub sij hawm quenching, siab creep zog thiab ruaj khov ntawm kub kub.

Siv los tsim cov forgings uas yuav tsum tau muaj zog dua thiab loj dua quenched thiab tempered seem tshaj 35CrMo steel, xws li: loj zog rau locomotive traction, supercharger kis tau tus mob zog, siab hlab ntsha zog, rear qag, tsis tshua muaj loaded txuas rods thiab springs Nws kuj yuav siv tau rau roj sib sib zog nqus zoo laum yeeb nkab txuas thiab cov cuab yeej nuv ntses hauv qab 2000m; thiab tuaj yeem siv rau pwm ntawm cov tshuab dabtsi yog khoov, thiab lwm yam.

2) 20CrMnTiH iav steel yog carburizing steel nrog kev ua tau zoo, siab harden-muaj peev xwm, nyuaj thiab hnav-resistant nto thiab tawv tub ntxhais tom qab carburizing thiab quenching, kub tsis tshua muaj kev cuam tshuam toughness, nruab nrab weld-muaj peev xwm, thiab tuaj yeem welded tom qab normalizing zoo. machinability.

Nws yog siv los tsim cov khoom tseem ceeb nrog ntu ntu <30mm uas tiv taus kev kub ceev, nruab nrab lossis hnyav, cuam tshuam thiab kev sib txhuam; xws li: iav, nplhaib iav, iav ncej ntoo khaub lig-lub taub hau, thiab lwm yam. Nws yog ib tug hloov steel rau 18CrMnTi, uas yog dav siv los ua carburized qhov chaw. Nws yog siv rau hauv tsheb thiab tsheb laij teb kev lag luam nrog ib ntu hauv qab 30mm; nws yog ib qho tseem ceeb ntawm carburized uas bears high-speed, nruab nrab los yog hnyav loads thiab yuav raug cuam tshuam thiab kev sib txhuam;
