Stainless hlau yog ib hom hlau. Hlau yog hais txog cov uas muaj cov pa roj carbon (C) qis dua 2%, uas yog hu ua hlau, thiab ntau tshaj 2% yog hlau. Ntxiv chromium (Cr), npib tsib xee (Ni), manganese (Mn), silicon (Si), titanium (Ti), molybdenum (Mo) thiab lwm yam hlau alloy thaum lub sij hawm smelting txheej txheem ntawm cov hlau txhim kho cov kev ua tau zoo ntawm cov hlau thiab ua rau cov khoom siv hlau. steel corrosion resistant (tsis muaj xeb) yog qhov peb feem ntau hais txog stainless hlau.
Dab tsi yog "steel" thiab "hlau", dab tsi yog lawv tus yam ntxwv, thiab lawv txoj kev sib raug zoo yog dab tsi?Peb feem ntau hais li cas 304, 304L, 316, 316L, thiab dab tsi yog qhov txawv ntawm lawv?
Hlau: Cov khoom siv hlau ua lub ntsiab lus tseem ceeb, cov ntsiab lus carbon feem ntau qis dua 2%, thiab lwm yam.
—— GB / T 13304－91 《Steel Classification》
Hlau: Cov khoom siv hlau uas muaj atomic tooj 26. Cov ntaub ntawv hlau muaj zog ferromagnetism, thiab muaj cov yas zoo thiab sib hloov.
Stainless hlau: resistant rau huab cua, chav, dej thiab lwm yam tsis muaj zog corrosive media los yog stainless hlau. Feem ntau siv steel hom yog 304, 304L, 316, thiab 316L, uas yog 300 series steels ntawm austenitic stainless hlau.
