GB / T 20Mntib Tshwj Xeeb Alloy
Qhov no yog ib qho chaw hloov chaw rau 20crmnti, ib alloy txheej txheem hlau nrog cov khoom siv neeg zoo thiab cov txheej txheem txheej txheem. Lub cheeb tsam tseem ceeb tshaj plaws hauv cov roj yog 14 ~ 27 hli. Nws muaj cov tshuab raj zoo tom qab ib txwm ua tau thiab muaj lub zog qaug zog zoo heev thiab deformation tom qab kev kho cua sov. Thiab cov ntsiab lus tsis txaus ntseeg nyob rau hauv cov khoom khoov tom qab carburization tsis tsawg tshaj li 20cmnti; Ib qho ntxiv, qhov nyiam ntawm cov qoob loo loj hlob thaum lub carburization me me, yog li qhov ntsuas kub tau qis dua (tsis txhob txo qis
