347H stainless hlau coiled raj
Alloy 347H yog ib qho stabilized, austenitic, chromium steel uas muaj columbium uas tso cai rau tshem tawm cov nag lossis daus ntawm carbide, thiab, yog li ntawd, intergranualr corrosion.Alloy 347 yog ruaj khov los ntawm kev ntxiv ntawm chromium thiab tantalum thiab muaj ntau dua creep thiab kev nyuaj siab rupture zog tshaj alloy 304 thiab 304L uas kuj yuav siv tau rau exposures qhov twg rhiab heev thiab intergranualr corrosion muaj kev txhawj xeeb.Qhov sib ntxiv ntawm columbium kuj tso cai rau Alloy 347 kom muaj kev tiv thaiv corrosion zoo heev, txawm tias zoo tshaj ntawm alloy 321. 347H yog cov pa roj carbon ntau dua ntawm Alloy 347 thiab ua kom pom kev txhim kho qhov kub thiab txias.Haosteel Stainless cov khoom muag tam sim no suav nrog Alloy 347/347H (UNS S34700 / S34709) hauv cov ntawv, ntawv coil, phaj, puag ncig bar, ua tiav tiaj tiaj thiab cov khoom siv tubular.
