ASTM A302 boiler nkoj phaj yog manganese-molybdenum thiab manganese-molybdenum-nickel alloy steel phaj rau siab hlab ntsha.ASTM A302 boiler nkoj steel yog muaj nyob rau hauv plaub qib, xws li, Qib A, Qib B, Qib C, thiab Qib D. A thiab D muaj npib tsib xee ua cov tshuaj lom neeg. Ntawm lawv, Qib C thiab Qib D muaj cov tshuaj muaj pes tsawg leeg nickel. Nyob rau hauv tib lub thickness, lub zog tawm los thiab tensile lub zog ntawm ASTM A302 boiler nkoj phaj ntawm Qib B thiab Qib C yog tib yam, tab sis elongation ntawm Qib C phaj siab dua.
Cov khoom ntawm ASTM A302 boiler phaj yog raws li nws cov manganese-molybdenum-nickel muaj pes tsawg leeg.Lub thickness ntawm ASTM A302 boiler phaj tsuas yog txwv los ntawm lub peev xwm ntawm chemistry kom tau raws li cov kev cai ntawm cov cuab yeej cuab tam.
ASTM A302 Boiler Vessel Phaj yog dav siv nyob rau hauv kev tsim cov hlab ntsha siab, boilers, tso tsheb hlau luam thiab kub exchangers nyob rau hauv cov roj thiab roj tej yaam num.
