ASTM A387 Qib 11 Chav Kawm 1yog chromium-molybdenum (Cr-Mo) alloy steel phaj rau siab-kub siab cov hlab ntsha thiab boilers, muaj roughly 1.25% chromium thiab 0.5% molybdenum rau superior zog, creep resistance, thiab oxidation kuj nyob rau hauv hnyav ib puag ncig xws li roj & lub hwj chim, refined thiab tempered iav. Chav Kawm 1 qhia txog qib tensile lub zog tshwj xeeb, qhov txawv ntawm Chav Kawm 2, nrog rau qib no hais txog kev purity thiab qhov tsis haum rau kev thov.
