ASTM A203 Qib B Cov Khoom Siv yog Nickel Alloy Hlau Phaj tsuas yog siv rau welded siab cov hlab ntsha hauv qhov chaw kub tsawg. Raws li ib qho teeb meem ntawm kev coj ua hlau, cov hlau yuav tsum tau tua thiab yuav tsum ua kom zoo nrog grain zoo loj loj yuav tsum muaj. Tej yam yuav tsum tau kho tshav kub rau txhua daim hlau tau npaj tseg, thiab txhua daim hlau hauv qab A203 Qib B yuav tsum yog ib txwm ua.
