yuav tsum tau siv nyob rau hauv qhov siv thiab ua anti-kev sib txhuam bearings. Thiab 52100 kabmob steel yog lub feem ntau steel qib nyob rau hauv ASTM A295 txheem rau high-carbon anti-kev sib txhuam kev coj tus kheej hlau.
Yuav ua li cas yog 52100 kabmob steel?
AISI / ASTM
52100 kabmob steel yog ib tug siab carbon, chromium uas muaj tsawg hlau
steel uas yog los ntawm hardening thiab muab sau nyob rau hauv particular rau kev siv raws li
bearings.
52100 kabmob steel yog ib hom ntawm tshwj xeeb steel nrog nta ntawm
lub siab coj kuj thiab dov qaug zog lub zog. High-carbon chromium
kev coj tus kheej steel, engineering hlau thiab ib co hom stainless hlau thiab
tshav kub resistant steel yog siv raws li cov ntaub ntawv ntawm bearings thiab lwm
lub hom phiaj.
