Qib 316 yog tus qauv molybdenum-bearing qib, thib ob hauv qhov tseem ceeb rau 304 ntawm austenitic stainless hlau.Lub molybdenum muab 316 zoo tag nrho corrosion resistant zog tshaj Qib 304, tshwj xeeb tshaj yog siab dua rau pitting thiab crevice corrosion nyob rau hauv chloride ib puag ncig.
Stainless hlau - Qib 316L - Khoom, Fabrication thiab Daim Ntawv Thov (UNS S31603)
Qib 316L, qis carbon version ntawm 316 thiab tiv thaiv kab mob los ntawm rhiab heev (grain ciam teb carbide nag lossis daus).Yog li nws tau siv dav hauv cov ntsuas hnyav welded Cheebtsam (tshaj li 6 hli).Feem ntau tsis muaj nqi sib txawv ntawm 316 thiab 316L stainless hlau.
Cov qauv austenitic kuj muab cov qhab nia zoo heev, txawm tias mus rau qhov kub thiab txias.
Piv rau chromium-nickel austenitic stainless hlau, 316L stainless hlau muaj ntau dua creep, kev nyuaj siab rau rupture thiab tensile lub zog ntawm siab kub.
