Alloy sawv cev rau kev sib xyaw ua ke zoo heev ntawm corrosion kuj thiab fabricability. Cov neeg siv yav dhau los ntawm AISI 302 Stainless Steel Phaj feem ntau tam sim no siv 304 alloy txij li AOD thev naus laus zis tau ua kom qis cov pa roj carbon ntau yooj yim dua thiab pheej yig dua. Muaj cov piv txwv, xws li hauv cov khoom kub hnyiab, thaum AISI 302 Stainless Steel Phaj alloy nyiam dua 304 txij li cov pa roj carbon ntau dua tso cai rau lub rooj sib tham ntawm cov txiaj ntsig thiab lub zog tensile uas yuav tsum tau muaj thaum tuav cov qib siab dua ntawm cov ductility (elongation) piv rau cov pa roj carbon tsawg dua. T304. Qhov tseeb 302 yaj yog tsis tshua muaj raws li feem ntau yog siv 304 thov raws li 304 thiab AISI 302 Stainless Steel Phaj daim ntaub ntawv. Tag nrho 304 tuaj yeem tsim nyog raws li 302 vim nws yog ib feem ntawm 302 tab sis tsis yog tag nrho 302 tuaj yeem yog 304.
