Ob lub alloys no zoo sib xws hauv lawv cov tshuaj muaj pes tsawg leeg -tab sis muaj ib qho tseem ceeb sib txawv. Hauv qib 304 stainless hlau, qhov siab tshaj plaws carbon ntsiab lus yog teem rau ntawm 0.08%, thaum qib 304L stainless hlau muaj cov ntsiab lus siab tshaj plaws ntawm 0.03%. Qhov no yog vim li cas tus "L" hauv 304L tuaj yeem txhais tau tias lub ntsiab lus ntxiv - qis carbon.

 

Txawm hais tias muaj ntau qib thiab ntau yam ntawm stainless hlau tawm muaj nyob rau hauv kev ua lag luam, lawv muab cov khoom zoo sib xws ntawm corrosion kuj thiab siab zog. Txhua qib muaj qhov sib txawv ntawm cov khoom no. Thaum piv rau cov qauv hlau, cov khoom siv hlau tsis muaj steel feem ntau txhais ua kev tiv thaiv corrosion, siab dua ductility, siab tensile zog, thiab ob qho tib si siab dua cryogenic thiab kub toughness.
