Alloy 347 stainless hlau yog Austenitic stainless hlau uas muaj stabilizing ntsiab. Cov alloys tau yooj yim welded yooj yim. Annealing tuaj yeem tsis tau tom qab vuam tshwj tsis yog muaj kev ntxhov siab kev pab yog xav tau. 347 Stainless hlau tau ua tau zoo heev rau oxidation thiab corrosion. Nrog lub zog siab loj, 347 stainless hlau ua haujlwm zoo tshaj plaws txog 1600 degree F. Ntxiv rau columbium ntxiv tantalum hauv 347 stainless hlau muab qee yam yam xav tau zoo li:
Txwv tsis pub muaj kev phom sij carbide nag lossis daus hauv cov chaw kub (Hz) ntawm cov chaw weld
Imparts kev tiv thaiv ntau heev rau intergranular corrosion
Txo embrittlement nyob rau hauv HAZ ntawm qhov chaw weld
Cov Ntawv Thov
347 thiab 347H stainless hlau yog muaj nyob rau hauv cov roj refining industries. Alloy 347 thiab 347H stainless hlau yog siv los ua radiant superheaters, boiler hlab, siab siab chav yeeb nkab, thiab dav refinery piping. Lawv kuj tseem siv rau cov khoom siv hnyav hnyav thiab cov manifolds.
