X2CrNiMo17-12-2 vs 316L
X2CrNiMo17-12-2 thiab 316L yog cov khoom siv tib yam, sawv cev rau cov npe sib txawv rau tib cov pa roj carbon tsawg, austenitic stainless hlau. X2CrNiMo17-12-2 yog European tus qauv tsim (EN), thaum 316L yog Asmeskas tus qauv (AISI) tsim. Lub 'L' hauv 316L qhia txog nws cov ntsiab lus qis, uas txhim kho nws cov weldability thiab tsis kam mus rau intergranular corrosion piv rau tus qauv 316 steel.
Qhov txawv ntawm 3CR12 304 thiab 316 yog dab tsi?
Dab tsi txawv 316 ntawm 304 yog cov ntxhia hu ua molybdenum. Nrog rau qhov sib ntxiv ntawm 2-3% molybdenum, 316 muab hnyav- lub luag haujlwm corrosion tsis kam rau oxidisation thiab chloride-raws li raug. 3CR12 muab cov khoom zoo sib xws corrosion thiab kub ua haujlwm zoo li 304 thiab 316, nrog rau cov txiaj ntsig ntxiv ntawm weldability thiab formability.
