ASTM A387 Qib 11 sib npaug li cas?
ASTM A387 qib 11 sib npaug steel yog ASME SA387 qib 11. ASTM A387 qib 11 npog A387 qib 11 chav kawm 1 thiab A387 qib 11 chav kawm 2, uas sib npaug rau ASME SA387 qib 18 qib 71 thiab qib 12 raws.
Cov khoom siv ASTM A387 yog dab tsi?
ASTM A387 GR 22 CL 2 Phaj yog tsim los nrog cov tshuaj muaj pes tsawg leeg xws li carbon, manganese, phosphorus, molybdenum, chromium, silicon, thiab sulfur. Qhov no A387 alloy yog tsim los nrog ntau yam kev faib tawm xws li cheeb tsam txo qis, elongation, yield zog, thiab siab tensile zog.
Dab tsi yog qhov siab tshaj qhov kev pabcuam kub rau A387 Qib 11 Chav Kawm 1?
Qhov siab tshaj plaws kev pabcuam kub kub rau A387 Qib 11 Chav Kawm 1 feem ntau yog 540℃(1004℃F), raws li chromium-molybdenum alloy muaj pes tsawg leeg muab lub zog nkag tau zoo ntawm qhov kub siab. Kev ua haujlwm siab tshaj qhov kev txwv no rau lub sijhawm ntev yuav ua kom nrawm nrawm deformation, uas tuaj yeem ua rau ntau dhau thinning lossis rupture ntawm lub siab hlab ntsha phab ntsa ua ntej kawg ntawm lub neej kev pab cuam. Rau cov ntawv thov uas xav tau qhov kub thiab txias siab tshaj 540 degree, qib siab dua xws li A387 Qib 22 lossis Qib 91 yuav tsum raug txiav txim siab.
Puas yog post-weld heat treatment (PWHT) yuav tsum tau ua rau A387 Qib 11 Chav Kawm 1?
Yog lawm, tom qab-weld kev kho cua sov feem ntau yuav tsum tau ua rau A387 Qib 11 Chav Kawm 1 vim nws cov chromium- cov ntsiab lus molybdenum, uas ua rau muaj zog hardenability thiab kev pheej hmoo ntawm martensite tsim nyob rau hauv tshav kub- thaj tsam cuam tshuam tom qab vuam. PWHT, feem ntau ua tau ntawm 690–705℃(1275–1300℃F), txo qis qhov seem ntawm cov welding, tempers ib qho nyuaj microstructures, restores toughness, thiab tiv thaiv hydrogen-induced cracking, ua rau nws tus qauv yuav tsum tau raws li nyob rau hauv ASME Tshooj VIII thiab feem ntau siab hlab ntsha siv codes.
