Boiler Phaj Steel Khoom Taw Qhia
ASTM A302 boiler phaj yog hom hlau tsis tshua muaj hlau, suav nrog 4 qib sib txawv (A, B, C, D). Ntawm lawv, C-qib nkoj phaj thiab D-qib siab hlab ntsha hlau muaj cov tshuaj muaj pes tsawg leeg Ni. Thaum lub thickness yog tib yam, Qib C muaj tib lub zog tawm los thiab lub zog tensile li Qib B, thaum Qib C muaj qhov elongation ntau dua.
ASTM A302 alloy siab nkoj steel phaj Cov khoom no yog siv rau hauv cov hlab ntsha siab, boilers, cia tso tsheb hlau luam thiab kub exchangers nyob rau hauv cov roj thiab roj tej yaam num.
