SUS316L stainless hlau yog dab tsi?
SUS316L yog austenitic stainless hlau uas muaj cov pa roj carbon tsawg thiab molybdenum. Nws muaj nuj nqis heev rau nws qhov tshwj xeeb tsis kam rau chloride pitting corrosion, intergranular corrosion thiab crevice corrosion. Qhov "L" qhia tias cov ntsiab lus qis qis (tsawg dua lossis sib npaug li 0.03%), ua rau nws zoo tagnrho rau cov khoom siv muaj zog welded thiab corrosive marine los yog tshuaj lom neeg ib puag ncig.
SUS316 stainless hlau yog dab tsi?
SUS316 stainless hlau yog austenitic stainless hlau uas ua tau raws li Japanese Industrial Standards (JIS), sib npaug rau AISI 316 lossis UNS S31600. Nws muaj qhov tshwj xeeb corrosion kuj, ua rau nws tshwj xeeb tshaj yog haum rau ib puag ncig uas nplua nuj chlorides thiab acids. Nws tuaj yeem tsim tau rau hauv ntau yam khoom siv, xws li cov ntawv, coils, raj, tuav thiab xaim; Tsis tas li ntawd, nws ua tau zoo tshaj SUS304 hauv kev xav tau kev ua haujlwm xws li cov uas pom hauv dej hiav txwv, cov txheej txheem tshuaj lom neeg thiab kev siv dej hiav txwv engineering.
Qhov txawv ntawm SUS316L thiab SUS316 yog dab tsi?
Qhov sib txawv tseem ceeb ntawm SUS316 thiab SUS316L yog nyob rau hauv lawv cov ntsiab lus carbon. Tsab ntawvltxhais tau tias tsawg carbon (Low Carbon). Qhov siab tshaj carbon ntsiab lus ntawm SUS316L yog 0.03%, thaum cov pa SUS316 tso cai mus txog 0.08%. Cov ntsiab lus qis dua tiv thaiv carbide nag lossis daus thaum lub sijhawm vuam thiab txhim kho kev tiv thaiv intergranular corrosion.

SUS316 Stainless hlau vs SUS316L: Corrosion kuj
Ob leeg SUS316 thiab SUS316L stainless hlau muaj zoo heev corrosion kuj; Txawm li cas los xij, vim nws cov ntsiab lus qis dua (SUS316L muaj tsawg dua lossis sib npaug li 0.03% carbon, thaum SUS316 muaj tsawg dua lossis sib npaug li 0.08%), SUS316L muaj kev tiv thaiv zoo dua rau kev sib xyaw ua ke tom qab vuam. Nyob rau hauv ib puag ncig xws li cov dej hiav txwv, cov chaw tsim tshuaj lom neeg thiab cov kua qaub, SUS316L tsis tshua muaj kev tsim cov chromium carbide precipitates ntawm grain ciam teb thaum vuam los yog raug kub kub, ua rau nws ib tug ntau txhim khu kev qha kev xaiv nyob rau hauv lub sij hawm ntev corrosion kuj.
SUS316 vs SUS316L: Weldability
Ob leeg SUS316 thiab SUS316L muaj qhov zoo tshaj plaws weldability thiab tuaj yeem ua tiav los ntawm kev siv vuam xws li TIG, MIG thiab tsis kam vuam. Hauv kev sib piv, thaum SUS316 stainless hlau siv rau hauv cov ntawv thov tseem ceeb, nws yuav xav tau kev kho cua sov tom qab vuam los kho nws cov corrosion kuj.
