Tsawg Alloy A387 Qib 11 Class1 lossis Class 2 Steel Phaj

A387 Qib 11 Phaj yog ua los ntawm chrome moly steel raws li ASTM / ASME A387 tus qauv thiab yog tsim los siv rau hauv cov welded boilers thiab cov hlab ntsha siab siv lub siab kub. ASTM A387 Qib 11 Alloy Steel Phaj muaj Chromium thiab Molybdenum ua alloying ntsiab kom muab cov cua sov thiab corrosion tsis kam tshaj li ua rau ASTM A387 Qib 11 Alloy Steel Phaj Chav Kawm 1 Phaj siv rau qhov kub thiab txias.

Cov ntsiab lus Cr 1.25% thiab Mo cov ntsiab lus 0.5%. Txhua qib tshwj tsis yog qib 21L, Qib 22L, Qib 91 thiab Qib 911 muaj nyob rau hauv ob chav kawm ntawm qib tensile zog. Qib 91 thiab Qib 911 tsuas yog muaj raws li Chav Kawm 2.peb yog exporter ntawm astm a387 qib 11 chav kawm 2 phaj.

Raws li lub siab lub nkoj qib steel phaj siv rau hauv kev pabcuam kub siab, A387 Qib 11 Phaj yog siv ntau yam kev lag luam thiab muaj txiaj ntsig zoo, tshwj xeeb tshaj yog nyob rau hauv kev lag luam roj, roj thiab petrochemical, uas cov kua thiab roj feem ntau khaws cia ntawm qhov kub thiab txias. .
