astm siab nkoj Cov Khoom Piav Qhia
ASTM A387 boiler nkoj phaj yog chromium-molybdenum alloy steel phaj haum rau vuam boilers thiab siab hlab ntsha rau siab kub.ASTM A387 siab hlab ntsha hlau yog muab faib ua 5, 9, 11, 12, 22, 91 thiab lwm qib raws li cov alloying. cov ntsiab lus nws muaj.
Ntxiv rau 21L, 22L, 91 thiab 911, txhua qib ntawm ASTM A387 boiler steel phaj raws li nws cov kev kho cua sov thiab muaj ob pawg tensile zog: chav kawm 1 thiab chav kawm 2. ASTM A387 steel boiler phaj thickness tsuas yog txwv los ntawm lub peev xwm ntawm cov tshuaj muaj pes tsawg leeg kom ua tau raws li cov txheej txheem kho tshuab.
Cov ntsiab lus molybdenum ntawm ASTM A387 siab lub nkoj steel phaj txhim kho nws lub zog tensile ntawm qhov kub thiab txias thiab muab kev tiv thaiv siab rau oxidation thiab corrosion los ntawm kev sib zog lattice.
