ASTM A403 Rau Stainless Hlau Piping Fittings
ASTM A403 yog tus qauv tshwj xeeb ntawm wrought austenitic stainless hlau piping fittings.
Qhov kev qhia tshwj xeeb no suav nrog tus qauv rau wrought austenitic stainless hlau fittings rau kev siv cov kav dej siab. Cov khoom siv rau fittings yuav tsum muaj forgings, tuav, phaj, los yog seamless los yog welded tubular khoom. Forging los yog shaping kev khiav hauj lwm yuav tsum tau ua los ntawm hammering, nias, tho, extruding, chim siab, dov, dabtsi yog khoov, fusion vuam, machining, los yog ua ke ntawm ob los yog ntau tshaj ntawm cov kev khiav hauj lwm. Tag nrho cov fittings yuav tsum tau kho cua sov. Kev tshuaj xyuas tshuaj thiab cov khoom lag luam yuav tsum tau ua thiab ua raws li cov tshuaj muaj pes tsawg leeg hauv cov pa roj carbon, manganese, phosphorus, sulfur, silicon, chromium, molybdenum, thiab titanium. Kev ntsuam xyuas nruj yuav tsum ua tiav ntawm cov khoom siv los txiav txim siab lub zog tensile xws li lub zog tawm los thiab lub zog tensile. Fittings muab nyob rau hauv qhov kev qhia tshwj xeeb no yuav tsum tau tshuaj xyuas qhov pom ntawm qhov tsis sib xws, kev kuaj xyuas saum npoo, thiab cov khoom siv tshuab.

Kev kho cua sov
1. Txhua qhov fittings yuav tsum tau muab tso rau hauv cov cua sov kho. Rau cov qib H, cais cov kev kho cua sov yog xav tau rau kev daws teeb meem annealing; Kev kho cua sov hauv cov txheej txheem tsis raug tso cai los ua ib qho kev hloov pauv rau kev sib cais kev kho annealing. Cov txheej txheem kho cua sov, tshwj tsis yog rau cov qib uas teev nyob rau hauv 2., yuav tsum muaj cov tshuaj annealing cov fittings ntawm qhov tsawg kawg nkaus kub ntawm 1900 degree F [1040 degree] kom txog rau thaum chromium carbides mus rau hauv cov tshuaj, thiab ces txias ntawm ib tug txaus tus nqi. tiv thaiv nag lossis daus.

Ib qho tshuaj annealing kub siab tshaj 1950 degree F [1065 degree] tuaj yeem ua rau tsis zoo rau kev tiv thaiv intergranular corrosion tom qab raug rau sensitizing tej yam kev mob nyob rau hauv 321, 321H, 347, thiab 347H. Thaum tus neeg yuav khoom tau teev tseg, qhov ntsuas kub qis dua lossis kev daws teeb meem anneal yuav tsum tau siv tom qab pib qhov ntsuas kub kub anneal (saib Cov Lus Qhia Ntxiv S2).
3. Txhua qhov vuam yuav tsum tau ua ua ntej kev kho cua sov.
4. Fittings machined ncaj qha los ntawm tov-annealed forgings thiab bar Tshuag yuav tsum tsis txhob daws teeb meem annealed.
