Txhawb tshuaj

904L yog ib cov pa roj carbon tsawg heev uas muaj cov ntsiab lus zoo austenitic stainless hlau. Cov hlau tsim tau rau cov mob hnyav corrosion. 904L tau tsim qauv hauv ntau lub teb chaws tam sim no, thiab twb tau txais kev pom zoo hauv kev tsim cov hlab ntsha siab.


904L alloy nrog siv tib yam li CrNi austenitic steel, muaj qhov zoo tiv thaiv pitting thiab crevice corrosion muaj peev xwm, muaj kev ntxhov siab ntau txheej corrosion tawg peev xwm, zoo intergranular corrosion kuj cuab yeej, zoo txheej txheem thiab Muag zoo. Qhov ntsuas kub siab tshaj plaws mus txog 1180 ℃ thaum kub forging, qhov kub tshaj plaws nres nres rau tsis pub tsawg dua 900 ℃. Cov hlau no tuaj yeem kub thaum lub xyoo1000 - 1150 ℃. Cov txheej txheem kev kho cua sov steel yog 1100 - 1150 ℃, txias sai dua ua haujlwm sov. Txawm hais tias qhov no yuav siv cov txheej txheem vuam vias siv tshuab rau vuam, tab sis txoj kev zoo tshaj yog phau ntawv arc vuam thiab TIG vuam.


Thaum siv phau ntawv arc vuam, vuam txuas taub yuav tsum tsis pub ntau tshaj 2.5 hli thaum vuam 6 hli phaj; lub vuam vuam hla yog tsawg dua 3.2 hli thaum lub thickness ntau dua 6 hli. Thaum xav tau kev kho kub tom qab vuam, tuaj yeem nrawm-txias tom qab tshav kub hauv 1075 - 1125 ℃. Thaum sivTIG vuam, cov hlau puv tuaj yeem siv nrog cov khoom siv tib yam, seam yog raug rau pickling, passivatingtreatment tom qab vuam.
