Lub ntsiab sib txawv ntawm cov zaub mov qib stainless hlau thiab stainless hlau yog:
Khoom noj khoom haus qib 304 stainless hlau yog qib ntawm stainless hlau ua raws li American ASTM tus qauv. Cov ntsiab lus tseem ceeb tshaj plaws hauv 304 yog Ni thiab Cr, tab sis lawv tsis txwv rau ob yam no. Cov cai tshwj xeeb yog stipulated cov qauv khoom. Qhov kev txiav txim siab ib txwm hauv kev lag luam yog tias ntev li ntev tau cov ntsiab lus Ni ntau dua 8% thiab cov ntsiab lus Cr yog ntau dua 18%, nws tuaj yeem suav tias yog 304 stainless hlau.
Stainless hlau yog qhov luv ntawm stainless thiab acid-resistant hlau. Stainless hlau yog hais txog cov hlau uas tiv taus cov xov xwm tsis muaj zog zoo li huab cua, chav, thiab dej, thiab cov tshuaj lom hauv cov ntawv tawm xws li acid, alkali, thiab ntsev. Nws kuj tseem hu ua steel acid-resistant steel. Kev txhim kho corrosion ntawm stainless hlau nyob ntawm cov alloying ntsiab hauv cov hlau.
Lub ntsiab alloying hauv stainless hlau yog Cr (chromium), thiab tsuas yog thaum Cr ntsiab lus nce mus txog ib qho nqi, cov hlau muaj xeb ua haujlwm. Yog li no, cov hlau stainless feem ntau muaj tsawg kawg 10.5% ntawm Cr (chromium). Stainless hlau tseem muaj cov ntsiab lus xws li Ni, Ti, Mn, N, Nb, Mo, Si, thiab Cu.
