ASTM A250 alloy steel kav muaj xws li qhov tsawg kawg nkaus phab ntsa tuab hluav taws xob tiv thaiv welded carbon-molybdenum thiab chrome-molybdenum alloy steels, boiler hlab thiab superheater hlab.
ASTM A250 alloy round tubes npog ntau qib, xws li T1, T1a, T1b, T2, T11, T12 thiab T22, thiab lwm yam. Qhov loj thiab tuab ntawm cov kav hlau steel yog dav, thiab cov kab sab nraud feem ntau yog los ntawm 1/2 mus rau 5 ntiv tes (12.7 mus rau 127 mm), thiab qhov tsawg kawg nkaus phab ntsa thickness yog 0.035 mus rau 0.320 nti (0.9 mus rau 8.1 mm), uas tuaj yeem muab tau raws li qhov tseeb cov kev xav tau ntawm cov neeg siv khoom.
ASTM A250 alloy boiler raj feem ntau yuav tsum tau kho cua sov los txhim kho lawv cov qauv thiab cov khoom. Cov kev kho cua sov uas muaj xws li normalizing, quenching thiab tempering.
