1.Dab tsi yog A387 qib 22 khoom?
Chrome Molybdenum Steel - ASTM A387 Qib 22 Chav Kawm 2. A387 Qib 22 Chav Kawm 2 - qib ntawm chromium-molybdenum alloy - yog tsim los siv rau hauv cov hlab ntsha siab thiab cov welded boilers, uas yog tsim los siv rau hauv qhov kub thiab txias.
2. Puas yog A387 qib 22 chav kawm 2 zoo dua A387 qib 22 chav kawm 1?
Yog lawm, ASTM A387 Qib 22 Chav Kawm 2 yog "zoo dua" dua li Chav Kawm 1 ntawm lub zog, vim nws muaj cov txiaj ntsig tsawg kawg nkaus thiab lub zog tensile, ua rau nws tiv taus kev ntxhov siab ntau dua, tab sis Chav Kawm 1 yuav nyiam dua rau kev tsim kho thiab weldability zoo dua vim qhov kev xav tau qis dua, vim tias ob qho tib si sib xyaw cov tshuaj muaj pes tsawg leeg tab sis txawv ntawm cov khoom siv tshuab.
