304 304L 316 316L Stainless hlau phaj lwm tus neeg nyob hauv Suav teb
Stainless hlau 304 yog cov qib stainless hlau siv dav tshaj plaws.Nws yog ib qho chromium-nickel austenitic stainless hlau uas muaj cov ntsiab lus ntawm cov pa roj carbon tsawg thiab me ntsis siab dua chromium thiab npib tsib xee dua li AISI hom 301 thiab 302. Qib 304 yog ductile heev thaum nyob rau hauv ib qho kev mob annealed.Nws muaj qhov kub siab zoo thiab zoo toughness ntawm qhov kub thiab txias.Nws yog qhov zoo rau kev vuam thiab qhov twg cov khoom tiav yuav tsum tiv taus cov ntaub ntawv hnyav dua ntawm corrosion.
