A387 gr 12 khoom yog dab tsi?
A387 Qib 12 Chav Kawm 2 yog cov khoom zoo chrome molybdenum hlau uas yog qhov zoo tagnrho rau kev pabcuam kub thiab muaj cov yam ntxwv zoo tiv thaiv corrosion. Cov hlau muaj ntau yam kev siv nrog rau kev lag luam boilers thiab cov hlab ntsha siab, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig uas muaj qhov kub thiab txias.
Qib 12 steel yog dab tsi?
Xa lus nug. Engineered rau siv nyob rau hauv siab kub kev pab cuam, yog ib tug chrome molybdenum carbon alloy hlau rau siv nyob rau hauv weldable siab hlab ntsha thiab muaj boilers.
Dab tsi yog qhov txawv ntawm ASTM A387 Qib 12 Chav Kawm 1 thiab Chav Kawm 2?
Qhov sib txawv tseem ceeb ntawm ASTM A387 Qib 12 Chav Kawm 1 thiab Chav Kawm 2 yog lawv cov khoom siv kho tshuab (lub zog), tsis yog lawv cov tshuaj lom neeg muaj pes tsawg leeg, nrog rau Chav Kawm 2 muab siab dua tensile thiab yield zog dua Chav Kawm 1 vim kev kho cua sov sib txawv (feem ntau quenching thiab tempering rau Chav Kawm 2 vs. normalizing/annealing for Class 1). Lub zog siab dua no hauv Chav Kawm 2 ua rau nws tsim nyog rau kev xav tau ntau dua, siab dua - kev ntxhov siab, thiab siab - qhov kub siab ntawm cov hlab ntsha.
