SA662 Qib B yog cov pa roj carbon manganese npib tsib xee cryogenic siab nkoj steel phaj raws li Asmeskas tus qauv ASME SA662 / SA662M. Nws yog siv rau nruab nrab thiab qis kub welded siab cov cuab yeej, nrog rau qhov tsawg kawg nkaus tsim kub ntawm -60 degree. Qhov kub tsis tshua muaj zog yog txhim kho los ntawm kev ntxiv nickel (0.40-0.70%) thiab normalizing kev kho mob. Nws yog dav siv nyob rau hauv LNG theem nrab cia tso tsheb hlau luam, cryogenic sib cais thiab tshuaj cryogenic ntim.
