440C thiab 420C stainless hlau pob yog ob qho khoom siv hauv kev tsim khoom. Ob hom hlau no paub txog lawv cov kav ntev, corrosion kuj, thiab toughness.
Tshuaj muaj pes tsawg leeg ntawm txhua yam khoom:
AISI 420C
C: 0.43-0.5%
Si: 1% max
Mn: 1% max
P: 0.04%Max
S: 0.03% Max
Cr: 12-14.5%
AISI 440C
C: 0.95-1.2%
Si: 1% max

P: 0.04%Max
S: 0.03% Max
Cr: 16-18%
Thawj qhov sib txawv ntawm ob lub pob stainless hlau yog nyob rau hauv lawv cov muaj pes tsawg leeg. AISI440C steel pob muaj cov pa roj carbon ntau dua li 420C steel pob, uas ua rau nws hnyav dua thiab tiv taus hnav thiab tsim kua muag. Ntawm qhov tod tes, 420C steel pob muaj cov ntsiab lus qis dua, ua rau nws yooj yim dua rau tshuab thiab zoo li qub.
440C stainless hlau pob yog qhov zoo tshaj plaws rau cov ntawv thov uas xav tau siab precision thiab zoo heev tiv thaiv corrosion. Nws yog feem ntau siv rau hauv kev tsim cov cuab yeej phais, bearings, li qub, thiab riam. Lub 420C stainless hlau pob, ntawm qhov tod tes, yog tsim rau kev siv dav dav xws li cov khoom siv tsheb, pob bearings, thiab tshuab qhov chaw.
Txawm hais tias qhov sib txawv no, ob qho tib si stainless hlau pob no yog cov khoom zoo thiab muaj kev ua tau zoo heev. Lawv yog cov pob loj loj, AISI420C HRC50-60, AISI440C HRC58-66
