A302 Boiler phaj
Boiler Steel Phaj Khoom Description
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, uas yog, Qib A, Qib B, Qib C, thiab Qib D. Cov tshuaj muaj nickel. Ntawm lawv, Qib C thiab Qib D muaj cov tshuaj muaj pes tsawg leeg nickel. Nyob rau hauv tib lub thickness, lub zog yield thiab tensile zog ntawm ASTM A302 steel boiler phaj ntawm Qib B thiab Qib C yog tib yam, tab sis elongation ntawm Qib C phaj siab dua.
Cov khoom ntawm ASTM A302 siab lub nkoj phaj yog raws li nws cov manganese-molybdenum-nickel muaj pes tsawg leeg.Lub thickness ntawm ASTM A302 boiler steel tsuas yog txwv los ntawm lub peev xwm ntawm cov tshuaj muaj pes tsawg leeg kom tau raws li cov kev cai ntawm txhua yam khoom.
ASTM A302 siab hlab ntsha steel phaj yog dav siv nyob rau hauv fabrication ntawm siab hlab ntsha, boilers, tso tsheb hlau luam thiab kub exchangers nyob rau hauv cov roj thiab roj tej yaam num.
