Stainless hlau alloy 347H

Hom 347H yog austenitic chromium hlau nrog cov ntsiab lus siab carbon. Lwm yam tseem ceeb tsim nta pom nyob rau hauv daim ntawv thov uas yuav tsum tau kub siab kam rau ua xws li:

Zoo sib xws corrosion kuj thiab kev tiv thaiv raws li Alloy 304

Siv rau cov khoom siv welded hnyav thaum annealing tsis tau

Zoo oxidation kuj, nyob rau hauv par nrog rau feem ntau lwm yam austenitic stainless hlau

Cov ntsiab lus carbon txhim kho qhov kub thiab txias creep zoo

Vim Hom 347H cov khoom tshwj xeeb nws tau siv ntau yam kev thov hauv ntau qhov kev lag luam tseem ceeb niaj hnub no:

Boiler raj thiab plhaub

Roj thiab roj refinery piping

Radiant superheaters

piping rau high-pressure chav

Thaum tshav kub kub exchanger tubes

Cov cua sov hauv tsev

Heavy phab ntsa-welded khoom

Lub dav hlau tso cov khoom sib tsoo thiab cov nplhaib sib dhos

Nrog rau qib siab dua ntawm cov pa roj carbon zoo li niaj zaus Hom 347, Hom 347H stainless hlau muaj cov tshuaj lom neeg tshwj xeeb uas suav nrog cov hauv qab no:

Fe balance

Cr 17-20 feem pua

Tsis yog 9-13 feem pua

C 0 04-0.08 feem pua

Mn {{0}} 5-2.0 feem pua

S 0.30 feem pua ​​max

Si 0.75 feem pua ​​max

P 0.03 feem pua ​​max

Cb/Ta 1% max

Txhua hom 347H stainless hlau uas muab los ntawm SSM, ua tau raws li cov qauv thoob ntiaj teb xws li ASTM, ASME, EN, thiab DIN.
