SS304 yog cov khoom siv hlau tsis zoo, tseem hu ua 18-8 stainless hlau uas muaj zog toughness thiab kub resistant 800 ℃ hauv kev lag luam, dav siv hauv kev lag luam thiab rooj tog kho kom zoo nkauj kev lag luam thiab khoom noj khoom haus thiab kev kho mob kev lag luam.
304 yog ntau yam stainless hlau hom uas yog dav siv los ua cov cuab yeej thiab cov khoom siv uas xav tau kev ua haujlwm zoo (corrosion resistance thiab molding). Yuav kom tswj tau qhov corrosion kuj muaj nyob rau hauv stainless hlau, cov hlau yuav tsum muaj ntau tshaj 18% chromium thiab ntau dua. 8% nickel cov ntsiab lus.The 304 Stainless Steel yog tsim raws li US ASTM cov qauv
