GB/T 3077 40cr Seamless Steel Yeeb Nkab

40Cr steel yeeb nkab yog tus qauv steel qib ntawm Tuam Tshoj GB, thiab 40Cr alloy steel yeeb nkab yog ib qho ntawm feem ntau siv steels hauv kev lag luam machinery manufacturing. Tom qab quenching thiab tempering kev kho mob, nws muaj kev zoo txhua yam khoom, zoo low-temperature impact toughness thiab low notch rhiab heev.
40Cr seamless steel yeeb nkab muaj zoo hardenability. Nws tuaj yeem hardened rau Ф28 ~ 60mm thaum lub sij hawm dej quenching thiab mus rau Ф15 ~ 40mm thaum lub sij hawm roj quenching. Ntxiv nrog rau quenching thiab tempering, cov hlau no kuj tsim nyog rau cyanidation thiab high-frequency quenching. Kev ua haujlwm txiav yog qhov zoo. Thaum lub hardness yog 174 ~ 229HB, tus txheeb ze txiav processability yog 60%. Cov hlau no yog tsim los ua cov yas pwm nruab nrab thiab cov khoom siv ncej.
40Cr alloy round raj yog quenched ntawm 850 degree, roj-txias; tempered ntawm 220 degree, dej-txias, roj-txias, thiab cua-txias. Qhov saum npoo quenching hardness yog 52-60HRC, thiab nplaim quenching tuaj yeem ncav cuag 48-55HRC.
