FAQ
Q: A387 Qib 11 yog dab tsi?
A: ASTM A387 specification yog Standard 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.
Q: Dab tsi yog SA 387 GR 11 Cl 1 khoom sib npaug?
A: Sa 387 Gr 11 Cov khoom sib npaug
Nrog cov chromium, molybdenum, thiab cov ntsiab lus tshuaj zoo sib xws, Sa 387 Gr 11 Cl 1 Equivalent Materials BS 621B nthuav tawm cov khoom zoo ib yam.
Q: Dab tsi yog qhov kub thiab txias SA 387 GR 11?
A: Nyob rau hauv qis kawg ntawm qhov kub ntawm SA 387 Gr 11 (1150℃F min tempering kub), thiab SA 387 Gr 22 (1250℃F min tempering kub) yog siv. Cov qib no tuaj yeem teev nyob rau hauv chav kawm 1 lossis 2 thiab tseem tuaj yeem muab rau hauv Normalized & Tempered lossis Quenched thiab Tempered.
Q: Qhov txawv ntawm SA 387 GR 11 cl1 thiab cl2 yog dab tsi?
A: Qhov txawv ntawm SA 387 Qib 11 Chav Kawm 1 thiab Chav Kawm 2 Phaj nyob hauv lawv cov khoom siv tshuab. Txawm li cas los xij, lawv ob leeg muaj tib yam tshuaj muaj pes tsawg leeg. Lub zog tensile thiab lub zog ntawm cov khoom siv hauv chav kawm 2 yog siab dua li ntawm chav kawm 1, qhov elongation rau chav kawm 1 yog siab dua piv rau chav kawm 2.
Q: Cov khoom siv SA 387 Qib 11 yog dab tsi?
A: Muaj pes tsawg leeg: ASME SA387 Qib 11 feem ntau muaj txog 1% chromium thiab 0.5% molybdenum. Cov khoom xyaw no muab lub zog zoo thiab ua haujlwm rau oxidation ntawm qhov kub thiab txias. Mechanical Properties: Tawm Zog: Tsawg kawg ntawm 205 MPa (30,000 psi)
Q: Qhov txawv ntawm SA 387 Qib 11 CL 1 thiab Chav Kawm 2 yog dab tsi?
