ASTM A387 boiler nkoj phaj yog chromium-molybdenum alloy steel phaj rau welded boilers thiab high-temperature siab hlab ntsha. muaj.
Ntxiv rau qib 21L, 22L, 91 thiab 911, txhua qib ntawm ASTM A387 boiler nkoj phaj raws li nws cov kev kho cua sov thiab muaj ob pawg tensile zog: chav kawm 1 thiab chav kawm 2. ASTM A387 boiler nkoj phaj thickness tsuas yog txwv los ntawm cov muaj peev xwm ntawm cov tshuaj muaj pes tsawg leeg kom ua tau raws li qhov yuav tsum tau muaj ntawm cov khoom siv kho tshuab.
Cov ntsiab lus molybdenum ntawm ASTM A387 boiler hlab ntsha 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.
