Dab tsi yog qhov txawv ntawm 304 stainless hlau luj tshib thiab 316 stainless hlau luj tshib?

Dab tsi yog qhov txawv ntawm 304 stainless hlau luj tshib thiab 316 stainless hlau luj tshib?
Stainless hlau luj tshib yuav tsis corrode, qhov, xeb los yog hnav. Kev tiv thaiv corrosion ntawm stainless hlau luj tshib txo qis thaum cov ntsiab lus carbon ntawm stainless hlau nce. Feem ntau stainless hlau luj tshib muaj cov ntsiab lus carbon tsawg. Tsuas yog thaum cov ntsiab lus Cr ncav cuag ib qho nqi, stainless hlau luj tshib muaj corrosion kuj. Yog li txhua leej txhua tus paub dab tsi yog qhov txawv ntawm 304 stainless hlau luj tshib thiab 316 stainless hlau luj tshib?

Qhov sib txawv ntawm 304 stainless hlau luj tshib thiab 316 stainless hlau luj tshib yog raws li nram no:

304 stainless hlau luj tshib yog dav siv stainless hlau luj tshib thiab kub-resistant steel luj tshib. Siv rau hauv cov khoom siv khoom noj khoom haus, cov khoom siv tshuaj lom neeg, lub zog nuclear, thiab lwm yam. 304 stainless hlau yog cov khoom siv stainless hlau ntau yam uas muaj zog tiv thaiv xeb ntau dua 200 series stainless hlau cov ntaub ntawv. Nws kuj yog qhov zoo ntawm qhov kub thiab txias, thiab tuaj yeem siab li 1000-1200 degrees. 304 stainless hlau muaj zoo heev stainless corrosion kuj thiab zoo intergranular corrosion kuj.

316 stainless hlau luj tshib yog siv nyob rau hauv kev lag luam khoom noj khoom haus, kev lag luam kws tshuaj thiab cov khoom siv phais. Qhov sib ntxiv ntawm molybdenum caij muab nws cov qauv tshwj xeeb corrosion-resistant. Nws cov kev tiv thaiv corrosion zoo dua li ntawm 304 stainless hlau luj tshib, thiab nws muaj kev tiv thaiv corrosion zoo nyob rau hauv cov ntaub ntawv thiab cov ntawv tsim tawm. Ntxiv mus, 316 stainless hlau luj tshib kuj yog resistant rau corrosion los ntawm dej hiav txwv thiab corrosive industrial cua. Tsis tas li ntawd, lub luj tshib 316 muaj cov tshuaj chloride corrosion zoo dua li 304 luj tshib.
