Raws li ASTM A387, chrome molybdenum alloy steel daim hlau muaj nyob rau hauv ob peb qib nrog sib txawv alloy compositions. Cov qib siv feem ntau suav nrog Qib 11, Qib 22, Qib 5, Qib 9, thiab Qib 91. Cov qib no yog qhov txawv los ntawm lawv cov ntsiab lus tshwj xeeb alloying thiab tsim los rau qhov sib txawv ntawm qhov kub thiab txias thiab corrosion kuj nyob rau hauv ntau yam kev siv, tshwj xeeb tshaj yog nyob rau hauv high-temperature ib puag ncig. xws li kev tsim hluav taws xob thiab kev lag luam.

Txhua qib tshwj tsis yog Qib 91 muaj nyob rau hauv ob chav kawm ntawm qib tensile lub zog raws li tau hais hauv Tensile Requirements tables. Qib 91 tsuas yog muaj raws li Chav Kawm 2. Qib 91 muaj ob hom, nrog Hom 2 sib txawv ntawm Hom 1 los ntawm kev xav kom muaj kev txwv tsis pub muaj kev txhim kho ntawm kev nkag mus.
Feem ntau siv steel specifications rau Chrome Moly phaj yog ASME SA387 thiab ASTM A387
• Chemical thiab mechanical zog ntawm ASME thiab ASTM specifications yog tib yam.
• Brown McFarlane muab Chrome Moly daim hlau rau ASME SA387 thiab ASTM A387 ob qho tib si los ntawm Tshuag thiab, qhov xav tau los ntawm cov neeg siv khoom, txiav kom loj thiab cov duab.
