Stainless hlau 316,316L, 316H

316 yog tus qauv molybdenum-cov kabmob qib, thib ob hauv qhov tseem ceeb rau 304 ntawm austenitic stainless hlau. Lub molybdenum muab 316 zoo dua tag nrho corrosion resistant zog tshaj 304, tshwj xeeb tshaj yog siab dua rau pitting thiab crevice corrosion nyob rau hauv chloride ib puag ncig. Nws muaj kev sib sau zoo heev thiab vuam yam ntxwv. Nws tau yooj yim nres lossis yob tsim rau hauv ntau qhov chaw rau kev siv hauv kev lag luam, kev tsim vaj tsev, thiab kev thauj mus los. 316 kuj muaj cov yam ntxwv zoo heev vuam. Post-weld annealing tsis tas yuav tsum tau thaum vuam nyias ntu.

316L, qis carbon version ntawm 316 thiab tiv thaiv los ntawm rhiab heev (grain ciam carbide nag lossis daus). Yog li nws tau siv dav hauv cov ntsuas hnyav welded Cheebtsam (tshaj li 6 hli).
316H, nrog rau nws cov ntsiab lus carbon ntau dua tau thov ntawm qhov kub siab, zoo li qib 316Ti ruaj khov.
Cov qauv austenitic kuj muab cov qhab nia zoo heev, txawm tias mus rau qhov kub thiab txias.
