SS316 vs SUS316 Stainless hlau: Dab tsi yog qhov txawv?
Tso lus
Yog tias koj tab tom nrhiav stainless hlau rau cov khoom siv tshuaj, cov qauv hauv hiav txwv, lossis zaub mov- cov ntawv thov qib, koj yuav tau ntsib cov ntsiab lus xws li SUS316, SS316, thiab SS316L. Cov qib no muaj kev sib raug zoo, tab sis muaj qhov sib txawv tseem ceeb-tshwj xeeb tshaj yog thaum nws los txog rau corrosion kuj, weldability, thiab ntev - kev ua tau zoo.
Daim ntawv qhia no piv SUS316 vs SS316L stainless hlau phaj, pab pawg neeg muag khoom thiab cov kws tsim khoom ua kev txiav txim siab.
SS316 Stainless hlau yog dab tsi?
SS316, tseem hu ua AISI 316, yog lub siab - zoo stainless hlau uas feem ntau siv rau hauv daim ntawv thov uas yuav tsum tau corrosion kuj thiab lub zog. Nws muaj 16-18% chromium, 10-14% npib tsib xee, thiab 2-3% molybdenum, uas ua rau nws muaj zog tiv thaiv chloride-induced corrosion.
SUS316 Stainless hlau yog dab tsi?
SUS316 yog qhov tseem ceeb zoo ib yam li SS316 tab sis yog Japanese cov qauv tsim lub npe rau cov khoom siv. SUS stands rau Steel Siv Stainless, thiab tus naj npawb 316 yog hais txog cov hlau muaj pes tsawg leeg thiab cov khoom. SUS316 ua raws li JIS (Japanese Industrial Standard), uas yog sib npaug rau SS316 hauv Asmeskas thiab lwm cov qauv thoob ntiaj teb.
Nyob rau hauv kev xyaum, SS316 thiab SUS316 yog tshuaj thiab mechanically zoo tib yam, thiab qhov txawv tsuas yog lub naming convention siv nyob rau hauv txawv cheeb tsam.

Puas yog SS316 qis- carbon stainless hlau zoo dua SUS316?
Yog lawm. SS316L feem ntau suav hais tias yog qhov zoo tshaj rau SUS316 hauv cov ntawv thov uas cuam tshuam nrog vuam lossis corrosive ib puag ncig vim tias nws cov ntsiab lus qis dua (tsawg dua lossis sib npaug li 0.03%) txo qhov kev pheej hmoo ntawm kev xa tawm -weld intergranular corrosion.
Thaum lub corrosion kuj thiab txhua yam khoom ntawm ob qib zoo sib xws, SS316L stainless hlau corrosion-cov phaj resistant yog nyiam rau cov hlab ntsha siab, cov khoom siv tu cev, thiab cov khoom uas yuav tsum ua raws li ASME lossis EN cov qauv. Txawm li cas los xij, SUS316 tseem tsim nyog rau cov uas tsis yog -welded Cheebtsam.
