Cov khoom siv SS316L yog dab tsi?
316L stainless hlau belongs rau tsev neeg ntawm austenitic stainless hlau thiab muaj lub ntsej muag-centered cubic (FCC) siv lead ua qauv. Nws tsis yog hlau nplaum thiab tsis tuaj yeem ntxiv dag zog los ntawm kev kho cua sov; Nws lub zog tsuas tuaj yeem txhim kho los ntawm kev ua haujlwm txias. Nws cov khoom tuaj nyob rau hauv daim ntawv, daim hlau, tuav, raj, strips, xov hlau thiab forgings.
316L stainless hlau muaj kev tiv thaiv zoo heev rau intergranular corrosion nyob rau hauv lub xeev sensitized, ua rau nws tshwj xeeb tshaj yog haum rau kev tsim khoom ntawm welded Cheebtsam thiab cov khoom siv nrog tuab hla ntu. Nws yog dav siv los ua cov khoom siv tiv thaiv corrosion hauv kev lag luam xws li petrochemicals, chiv tsim, ntawv tsim, textile dyeing thiab nuclear engineering.
Dab tsi yog cov khoom sib npaug rau SUS316L?
316L yog qib stainless hlau uas yog US ASTM tus qauv. Nws cov qib sib raug zoo nyob rau hauv Suav GB tus qauv system yog 022Cr17Ni12Mo2, thiab nws cov lej sib koom ua ke yog S31603. Kev lees paub thoob ntiaj teb sib npaug suav nrog Japanese JIS SUS316L thiab EU BSEN 1.4404.
Dab tsi yog cov khoom siv S31603?
S31603 yog lub koom haum Numbering System (UNS) rau 316L stainless hlau. Nws yog austenitic stainless hlau uas muaj cov pa roj carbon tsawg thiab molybdenum, paub txog nws qhov tshwj xeeb tiv thaiv corrosion, tshwj xeeb tshaj yog nyob rau hauv acidic thiab chloride-nplua nuj ib puag ncig.

Qhov twg zoo dua, SS316 lossis SS316L?
Tsis muaj leej twg yog universally "zoo dua"; Nws nyob ntawm koj qhov project xav tau. Yog tias koj tab tom vuam hlau, SS316L yog qhov kev xaiv zoo tshaj plaws, vim nws cov ntsiab lus qis qis tiv thaiv intergranular corrosion. Yog tias cov qauv muaj zog thiab tawv tawv yog koj qhov tseem ceeb tshaj plaws, SS316 zoo dua.
316 stainless hlau puas tuaj yeem siv los hloov 316L?
Yog lawm, 316 feem ntau tuaj yeem siv los hloov 316L (cov pa roj carbon tsawg), tshwj xeeb tshaj yog rau cov ntawv siv seamless lossis rau cov qauv siv dav dav. Txawm li cas los xij, vim nws cov ntsiab lus carbon ntau dua, 316 yog qhov cuam tshuam rau kev cuam tshuam ntawm intergranular corrosion yog tias cov khoom siv welded hnyav dua.
