Dab tsi yog qhov℃1.4404 sib npaug rau?
Cov Hom Hlau Stainless1.4401thiab1.4404yog tseem hu uaQib 316 thiab 316L, ntsig txog. Qib 316 yog cov hlau tsis muaj tshuaj tua kab, ntawm cov lag luam tseem ceeb thib ob tsuas yog 304. 316 Stainless Hlau muajmolybdenum, uas muab rau koj azoo dua corrosion tsis kampiv rau lwm tus kab mob stainless.
Dab tsi yog cov khoom siv 1.4571 sib npaug?
qib stainless hlau1.4571Sib npaug rauAISI 316TICov. Nws yog Austenitic Stainless hlau ruaj khov nrogTitanium, siv los ua kev txhim kho corrosion ntxiv rau 316L. Qib no yog tsiag ntawv los ntawm nwsZoo dua tsis kam rau intergranular corrosion, tshwj xeeb tshaj yog thaum muaj kub, ua tsaug rau ntxiv ntawm titanium.
