Dab tsi yog V4A stainless hlau?
Stainless hlau V4A yog austenitic stainless hlau uas suav nrog molybdenum, ua rau nws tiv taus corrosion, tshwj xeeb tshaj yog los ntawm cov dej ntsev thiab cov kua qaub. Nws tseem hu ua A4 stainless hlau thiab feem ntau sib npaug rau qib zoo li AISI 316, 1.4401, lossis 1.4404. Qhov no ua rau nws haum rau qhov hnyav ib puag ncig xws li kev siv dej hiav txwv, cov nroj tsuag tshuaj, thiab cov qauv sab nraum zoov.
V4A stainless hlau sib npaug
V4A yog ib qho kev tsim qauv qub rau qib siab - zoo austenitic stainless hlau, nrog rau nws qhov sib npaug tseem ceeb yog European tus qauv 1.4404, Asmeskas tus qauv AISI 316L, thiab cov npe dav dav A4. Nws yog lub npe hu rau nws zoo heev corrosion kuj vim qhov sib ntxiv ntawm molybdenum thiab feem ntau yog siv rau daim ntaub ntawv uas muaj dej ntsev los yog tshuaj.
Dab tsi yog qhov sib npaug ntawm 316 stainless hlau?
Qhov sib npaug rau 316 stainless hlau suav nrog European EN qib 1.4401, Japanese JIS qib SUS316, thiab British BS qib 316S31. Nws kuj yog qee zaum hu ua A4 hauv metric fastener qauv. Rau cov ntawv thov uas xav tau qis carbon tsawg, 316L yog qhov sib npaug, nrog rau nws tus kheej tsim xws li 1.4404 thiab 316S11.
Puas yog V4A stainless hlau zoo ib yam li 316?
Yog lawm, V4A stainless hlau yog qhov tseem ceeb zoo ib yam li AISI 316 lossis AISI 316L, nrog V4A yog German tus qauv tsim rau hom siab -molybdenum, corrosion-resistant steel. Qhov tseem ceeb zoo sib xws yog lawv cov muaj pes tsawg leeg, uas suav nrog chromium, npib tsib xee, thiab molybdenum, muab lawv zoo heev tiv thaiv corrosion nyob rau hauv ib puag ncig hnyav.

Dab tsi yog qhov txawv ntawm V2A thiab V4A stainless hlau?
Qhov sib txawv tseem ceeb yog tias V4A stainless hlau muaj corrosion ntau dua -resistant dua V2A vim nws muaj molybdenum ntxiv. V2A (los yog 1.4301 / AISI 304) yog qhov zoo rau kev siv dav dav, thaum V4A (los yog 1.4401/1.4404 / AISI 316) yog siv nyob rau hauv siab -chloride ib puag ncig xws li pas dej da dej, kev lag luam tshuaj, thiab kev siv dej hiav txwv. Ob leeg yog hom austenitic stainless hlau.
