440—High-lub zog txiav cuab tam steel nrog me ntsis siab dua cov ntsiab lus carbon. Tom qab kho cov cua sov kom zoo, cov txiaj ntsig ntau dua tuaj yeem tau txais. Lub zog ua tau ncav 58HRC, uas yog ntawm qhov nyuaj tshaj plaws steel hlau. Feem ntau cov ntawv thov piv txwv yog "chais plaub". Muaj peb tus qauv siv feem ntau: 440A, 440B, 440C, thiab 440F (yooj yimkev ua hom).
Lub hauv paus ntsiab lus ntawm stainless hlau pob:
Cov pob zeb tsis xeb tsis yog xeb, tab sis tsis yooj yim rau xeb. Lub hauv paus ntsiab lus yog tias los ntawm kev ntxiv ntawm chromium, ntau txheej chromium oxide txheej tsim nyob rau saum npoo ntawm cov hlau, uas tuaj yeem tiv thaiv kev sib kis rov qab ntawm cov hlau thiab huab cua, kom cov pa oxygen tsis tuaj yeem nkag rau hauv cov hlau pob, yog li tiv thaiv Qhov cuam tshuam ntawm steel pob rusting.
Tuam Tshoj Cov Qauv Hauv Tebchaws (CNS), Japanese Cov Qauv Kev Lag Luam (jis) thiab American Iron thiab Steel Institute (AISI) siv peb tus lej los qhia cov hlau sib txawv, uas tau hais ntau nyob rau hauv kev lag luam, ntawm qhov 200 series yog chromium-nickel-manganese. -based austenitic Stainless hlau, 300 series yog chromium-nickel austenitic stainless hlau, 400 series chromium stainless hlau (feem ntau hu ua stainless hlau), suav nrog martensite thiab ferrite.
