1.Qhov kub ntawm a387 qib 11 chav kawm 2 yog dab tsi?
ASTM A387 Qib 11 Chav Kawm 2 yog chromium-molybdenum steel tsim rau siab- cov hlab ntsha kub siab, feem ntau siv nyob rau hauv 350℃txog 480℃(660℃F txog 900℃F) ntau yam, nrog rau qhov yuav tsum tau ua kom tsawg kawg nkaus tempering kub ntawm 620℃F (115 degree) kev kho mob zoo heev tom qab kev kho cua sov (115 degree) thiab corrosion kuj nyob rau hauv siab - qhov kub thiab txias kev pab zoo li reactors thiab tshav kub exchangers.
2.A387 qib 11 yog dab tsi?
ASTM A387 specification yog tus qauv Specification rau Pressure Vessel Phaj, Alloy Steel, Chromium-Molybdenum npaj rau siv nyob rau hauv welded boilers thiab siab hlab ntsha tsim rau siab kub kev pab cuam. SSAB tuaj yeem muab A387 Qib 11 rau qhov kev xeem nruj rau Chav Kawm 1 thiab / lossis Chav Kawm 2.
3.A387 qib 11 chav kawm 2 muaj zog npaum li cas?
ASTM A387 Qib 11 Chav Kawm 2 yog ib qho muaj zog chromium-molybdenum alloy steel rau siab-kub siab cov hlab ntsha, muab lub zog tensile ntawm 75-100 ksi (515-690 MPa) thiab qhov tsawg kawg nkaus yield zog ntawm 43 ksi (310 MPa muaj zog dua), ua rau nws tsim nyog rau kev siv zog ntau dua 43 ksi (310 MPa ntau dua), ua rau nws tsim nyog. kev kho mob.
