FAQ
Q: Puas yog ASME SA387 Qib 11 tib yam li ASTM A387 Qib 11?
A: Yog lawm, ASME SA387 Qib 11 zoo ib yam rau ASTM A387 Qib 11. ASME (American Society of Mechanical Engineers) feem ntau siv thiab tsom iav ASTM (American Society for Testing and Materials) specifications rau cov khoom siv hauv siab.
Q: Yuav 13CrMo4-5 hloov ASTM A387 Gr.11?
A: Yog, 13CrMo4-5 (EN 1.7335) yog qhov zoo tshaj plaws nyob sab Europe sib npaug rau ASTM A387 Qib 11. Ob leeg yog 1.25Cr-0.5Mo cov hlau tsis tshua muaj hlau feem ntau tsim los rau cov kev pabcuam kub kub thiab cov hlab ntsha siab.
Q: Qhov txawv ntawm Chav Kawm 1 thiab Chav Kawm 2 hauv ASTM A387 yog dab tsi?
A: Hauv ASTM A387 (cov lus qhia tshwj xeeb rau alloy- cov phaj hlau siv hauv cov hlab ntsha siab thiab cov boilers), Chav Kawm 1 thiab Chav Kawm 2 qhia cov tshuaj muaj pes tsawg leeg zoo ib yam, tab sis txawv heev hauv lawv cov khoom siv kho tshuab (tensile thiab yield zog) vim cov txheej txheem kho cua sov sib txawv.
Q: Cov qib sib npaug twg muaj qhov zoo dua weldability, ASTM A387 GR.11 lossis GR.22?
A: ASTM A387 Qib 11 muaj qhov zoo dua, tsawg dua -sensitive weldability. Thaum ob leeg yog chromium-molybdenum (Cr-Mo) siab hlab ntsha steels yuav tsum nruj preheat thiab Post-Weld Thaum tshav kub kub kho (PWHT), Qib 11 muaj qis carbon sib npaug thiab qis hardness, ua rau nws tsis tshua muaj kev tawg thiab yooj yim rau vuam.
