A358 TP316L EFW welded yeeb nkab

 

316L stainless hlau welded kav yog dav siv nyob rau hauv kev lag luam tshuaj vim lawv zoo heev corrosion kuj. 316L steel yog ib qho derivative ntawm 18-8 hom austenitic stainless hlau, nrog ntxiv ntawm 2-3% molybdenum (Mo). Raws li 316L steel, ntau lwm yam hlau tau muab los, xws li 316Ti nrog me me ntawm titanium (Ti) ntxiv, 316N nrog me me ntawm nitrogen (N) ntxiv, thiab 317L nrog nce nickel (Ni) thiab Mo cov ntsiab lus .

Feem ntau 316L stainless hlau kav muaj nyob rau hauv kev ua lag luam yog tsim raws li American cov qauv. Rau kev xav txog tus nqi, steel mills feem ntau khaws Ni cov ntsiab lus ze rau qhov qis dua. Tus txheej txheem Asmeskas qhia txog Ni cov ntsiab lus ntawm 10-14% rau 316L, thaum tus qauv Japanese qhia txog Ni cov ntsiab lus ntawm 12-15%. Raws li tus qauv yam tsawg kawg nkaus, muaj 2% qhov sib txawv ntawm Ni cov ntsiab lus ntawm Asmeskas thiab Nyij Pooj cov qauv, uas cuam tshuam rau tus nqi. Yog li, cov neeg siv khoom yuav tsum tau kuaj xyuas seb cov khoom 316L lawv puas yuav ua raws li ASTM lossis JIS cov qauv.

Mo cov ntsiab lus nyob rau hauv 316L steel muab nws zoo heev corrosion kuj, ua rau nws muaj kev ruaj ntseg siv nyob rau hauv ib puag ncig uas muaj halide ions xws li chloride (Cl-). Txij li thaum daim ntawv thov tseem ceeb ntawm 316L welded kav yog rau lawv cov khoom siv tshuaj, steel mills muaj me ntsis qis dua qhov yuav tsum tau soj ntsuam rau 316L stainless hlau hluav taws xob fusion welded kav piv rau 304. Cov neeg siv khoom zoo dua qhov yuav tsum tau ua kom lawv cov kev soj ntsuam saum npoo.
