40scr Hloov Bar Tshuag Steel
40crlic bar steel bar yog tus qauv hlau tus naj npawb ntawm Tuam Tshoj GB, 40cr steel yog ib qho ntawm cov hlau siv dav hlau hauv kev lag luam machinery tsim. Qhov kev kho tempering muaj zoo tag nrho cov khoom siv tshuab, zoo tsawg {{3} kub cuam tshuam todness thiab low notch. Steel hardenability yog qhov zoo, dej quenching tuaj yeem twv mus rau ntawm ф28 ~ 60 hli, roj quenching tuaj yeem quenched rau ф ф15 ~ 40 hli. Cov hlau no ntxiv rau qhov ua kom sov siab yog qhov tsim nyog rau cyanide thiab siab zaus quenching kev kho mob. Kev txiav kev ua tau zoo yog qhov zoo, thaum lub hardness ntawm 174 ~ 229HB, txheeb ze txiav thiab machines rau 60%. Cov hlau tsim nyog rau kev ua nruab nrab- qhov loj me moulds.
