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.
Dab tsi yog qhov muaj pes tsawg leeg ntawm A387 steel?
Muaj pes tsawg leeg: ASTM A387 steel phaj feem ntau muaj chromium (txog 9% lossis ntau dua) thiab molybdenum (txog 2.25% lossis ntau dua), uas txhim kho lawv lub zog thiab corrosion kuj ntawm qhov kub thiab txias.
