2.Dab tsi yog qhov txawv ntawm SA 387 Qib 11 CL 1 thiab Chav Kawm 2?
Qhov sib txawv tseem ceeb ntawm A387 Qib 11 Chav Kawm 1 thiab Chav Kawm 2 yog lawvmechanical zog, nrog rau Chav Kawm 2 muaj zog tensile thiab yield zog ntau dua, ua rau nws tsim nyog rau kev xav tau ntau dua, siab dua - kev siv kev ntxhov siab, thaum ob qho tib si sib koom tib yam chromium-molybdenum tshuaj muaj pes tsawg leeg rau kev pabcuam kub siab. Chav Kawm 2 yog qhov siab dua - lub zog version, ua tiav los ntawm kev kho cua sov tshwj xeeb, xav tau kev ua haujlwm ntau dua hauv siab - kub, siab - cov hlab ntsha siab thiab boilers.
