316L yog ib qho derivative ntawm 18-8 hom austenitic stainless hlau. Nws tsuas yog muaj Cr, Ni, Mo, thiab lwm yam hlau, thiab ntxiv 2 mus rau 3 feem pua ntawm Mo cov ntsiab lus. Nws cov ntsiab lus Mo ua rau nws muaj kev tiv thaiv corrosion zoo heev thiab tuaj yeem ruaj ntseg Nws yog siv rau hauv ib puag ncig uas muaj halogen ions xws li Cl-. Txawm li cas los xij, txij li Mo yooj yim reacts nrog high-valent sulfur ions los tsim sulfides, nws yuav siv tsis tau nyob rau hauv ib tug concentrated sulfuric acid ib puag ncig.
Nws muaj qhov tsim nyog corrosion kuj nyob rau hauv ntau yam organic acids, inorganic acids, alkalis, ntsev, thiab dej hiav txwv, thiab nws cov corrosion kuj nyob rau hauv txo acidic media yog ntau zoo dua 304 thiab 304L.
Hom 316L Stainless Hlau yog ib qho ntxiv-tsis tshua muaj carbon version ntawm Hom 316 uas txo qis carbide nag lossis daus nyob rau hauv tshav kub-cuam tshuam thaum vuam.
316 "L" yog qhov zoo tagnrho rau cov ntawv siv vuam hnyav, vim nws tsis tshua muaj kev cuam tshuam rau vuam lwj.

Ntantawm Stainless Hlau Phaj 316L
- Cov khoom txias-dov muaj qhov zoo nkauj thiab zoo nkauj zoo nkauj;
- Zoo heev corrosion kuj, tshwj xeeb tshaj yog pitting kuj, vim yog ntxiv ntawm Mo;
- Zoo heev kub-kub muaj zog
- Ua haujlwm zoo hardenability (tsis muaj zog hlau nplaum tom qab machining)
- Tsis yog-sib nqus nyob rau hauv cov khoom daws teeb meem;
- Muaj kev tiv thaiv zoo rau chloride nres
- Zoo heev tiv thaiv grain ciam corrosion
- 316 stainless hlau muaj oxidation kuj zoo nyob rau hauv intermittent siv hauv qab no 1600 degrees thiab nruam siv hauv qab no 1700 degrees
- Zoo heev ductility thiab toughness
- Resistant atmospheric corrosion thiab nruab nrab oxidizing thiab txo ib puag ncig. Nws kuj tiv thaiv corrosion nyob rau hauv cov pa phem marine atmospheres. Lub alloy muaj zoo heev tsis kam mus rau intergranular corrosion nyob rau hauv lub as-welded lub xeev
Adaim ntawv thov
- Cov khoom lag luam nrog cov kev cai tshwj xeeb rau kev tiv thaiv kab lis kev cai corrosion
- Siv nyob rau hauv daim ntawv thov uas annealing tom qab vuam yog tsis tau thiab qhov twg siab tshaj corrosion kuj yuav tsum tau.
- Siv rau cov khoom lag luam nrog cov kev xav tau siab ntawm intergranular corrosion kuj, nrog rau cov tshuab qhib cua hauv kev lag luam chemical, thee, thiab roj av, thiab cov nroj tsuag tshuaj.
- Nws yog dav siv nyob rau hauv marine thiab chemical daim ntaub ntawv, uas muaj xws li cov pa phem tswj cov cuab yeej, lab khoom, nkoj haum, nkoj li qub, thiab textile thiab kws tshuaj.
Ob qib 316 thiab 316L steels muaj lub zog nkag siab, kev ntxhov siab-rau-rupture, thiab tensile lub zog ntawm qhov kub thiab txias, nrog rau zoo heev corrosion kuj thiab lub zog zog. Cov qib no zoo tsim nyog rau kev tsim los yog tsim cov ntawv thov xws li cov khoom siv kho kom zoo, cov cuab yeej phais, cov hlua khi, cov ntaub ntawv thiab cov ntawv ua cov ntaub ntawv, thiab kev ua tshuaj.
