304 vs 316 Stainless Hlau: Yam Koj Yuav Tsum Paub
304 vs 316 Stainless Hlau: Yam Koj Yuav Tsum Paub
Qhov sib txawv tseem ceeb nyob rau hauv qhov tseeb tias 316 stainless hlau, vim qhov sib ntxiv ntawm molybdenum, muaj kev tiv thaiv corrosion zoo dua, ua rau nws zoo tagnrho rau cov chaw hnyav xws li marine lossis tshuaj nroj tsuag; thaum 304 stainless hlau muaj kev lag luam ntau dua thiab tsim nyog rau kev siv dav dav uas yuav tsum muaj kev tiv thaiv corrosion tsis siab . 304 stainless hlau muaj kev ua tau zoo dua, thaum 316 stainless hlau zoo dua me ntsis hauv siab - daim ntawv thov kub thiab weldability.
Dab tsi yog 304 stainless hlau yeeb nkab?
304 stainless hlau yog siab - cov khoom muaj zog nrog corrosion kuj zoo heev, ua rau nws zoo tagnrho rau cov kua dej. ASTM A312 yog tus qauv specification rau seamless thiab welded stainless hlau yeeb nkab.
Dab tsi yog 304 stainless hlau?
Hom 304 stainless hlau yog austenitic stainless hlau alloy nrog cov ntsiab lus siab nickel (8-10.5%), siab chromium cov ntsiab lus (18-20%), thiab ntxiv manganese, silicon, thiab carbon. Nws yog dav suav hais tias yog feem ntau siv austenitic stainless hlau.
Nws yog dav siv hauv cov hauv qab no:
Cov khoom dawb, xws li tub yees, tshuab ntxhua khaub ncaws, thiab lub tub yees
Hose clamps
Automotive tso pa system
Kub exchangers
Lub tank cia
Nws yog ib qho tseem ceeb hauv cov hlau niaj hnub, tshwj xeeb tshaj yog tsim rau cov cheeb tsam uas carbon steel tau yooj yim corroded.
Dab tsi yog 316 stainless hlau?
Zoo li 304 stainless hlau, 316 stainless hlau muaj cov ntsiab lus siab nickel thiab chromium, thiab tib theem ntawm manganese, silicon, thiab carbon. Qhov sib txawv tseem ceeb nyob rau hauv cov ntsiab lus molybdenum. 316 stainless hlau muaj 2-3% molybdenum, thaum 304 stainless hlau tsuas muaj cov lej xwb.
Daim ntawv thov ntawm 316 stainless hlau:
Cov khoom siv phais thiab kho mob
Jet engine Cheebtsam
Cov khoom siv tshuaj ua haujlwm
Marine ib puag ncig khoom siv
Cov khoom siv chav ua noj ua lag luam
Kev sib piv ntawm cov tshuaj muaj pes tsawg leeg thiab cov ntsiab lus alloying
