316 stainless hlau yog austenitic stainless hlau uas muaj kwv yees li ntawm 16-18 feem pua chromium, 10-14 feem pua npib tsib xee, 2-3 feem pua molybdenum, thiab cov kab ntawm lwm yam xws li carbon, manganese, thiab silicon.
Qhov sib ntxiv ntawm molybdenum rau 316 stainless hlau muab kev txhim kho corrosion nyob rau hauv ntau qhov chaw, nrog rau cov uas muaj cov tshuaj chloride siab. Cov ntsiab lus siab nickel kuj tseem txhawb nqa nws cov kev tiv thaiv corrosion thiab txhim kho nws lub peev xwm tiv taus qhov kub thiab txias.
Nyob rau hauv cov nqe lus ntawm nws metallurgy, 316 stainless hlau muaj ib tug austenitic microstructure, uas txhais tau hais tias nws siv lead ua qauv yog lub ntsej muag-centered cubic (FCC). Cov qauv no ua rau zoo heev toughness, ductility, thiab weldability, ua rau nws yog ib tug nrov xaiv rau ntau yam kev siv.
Ib qho tshwj xeeb ntawm 316 stainless hlau yog tias nws tsis yog-magnetic nyob rau hauv lub annealed mob, uas ua rau nws haum rau daim ntaub ntawv uas sib nqus zog yog undesirable. Txawm li cas los xij, nws tuaj yeem dhau los ua cov hlau nplaum me ntsis tom qab ua haujlwm txias lossis vuam.
Zuag qhia tag nrho, metallurgy ntawm 316 stainless hlau muab kev sib xyaw ua ke zoo heev corrosion kuj, kub tsis kam, thiab cov khoom siv zoo, ua rau nws muaj ntau yam khoom siv thiab siv dav hauv ntau qhov kev lag luam.
