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.

Daim ntawv thov
Alloy 347H feem ntau siv rau kev tsim cov khoom siv, uas yuav tsum tau muab tso rau hauv kev pabcuam hauv cov xwm txheej hnyav hnyav, thiab tseem muaj rau cov roj av refining industries.
Corrosion Resistance:
.Muaj kev tiv thaiv zoo ib yam, tag nrho corrosion li Alloy 304
.Siv rau cov ntawv thov uas alloys xws li Alloy 304 yog qhov yooj yim rau intergranualr corrosion
.Feem ntau yog siv rau cov khoom siv welded hnyav uas tsis tuaj yeem raug annealed thiab rau cov khoom siv
uas ua haujlwm ntawm 800 txog 150 ° F (427 txog 816 ° C)
.Alloy 347 nyiam dua Alloy 321 rau aqueous thiab lwm qhov chaw kub tsis tshua muaj
.Feem ntau yog siv nyob rau hauv qhov kub thiab txias qhov chaw uas yuav tsum tau tiv thaiv rhiab heev, nyob rau hauv lem tiv thaiv intergranualr corrosion ntawm qis theem.
.Yooj yim rau kev ntxhov siab corrosion cracking
.Tso tawm oxidation kuj zoo ib yam li tag nrho lwm yam 18-8 austenitic stainless hlau
