Hom 347H yog lub siab carbon austenitic chromium stainless hlau. Pom muaj nyob rau hauv cov ntawv thov uas xav tau kev kub ntxhov siab, lwm yam qauv tsim muaj xws li:
- Zoo sib xws kuj thiab corrosion 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 pa roj carbon ntau dua tso cai rau kom zoo dua qhov kub thiab txias creep zog
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 casings
- Roj thiab roj refinery kav dej
- Radiant superheaters
- High-pressure chav kav
- Thaum tshav kub kub exchanger tubes
- Cov cua sov hauv tsev
- Heavy phab ntsa-welded khoom
- Lub dav hlau tso tsheb hlau luam thiab cov nplhaib sib dhos
Nrog rau qib siab dua ntawm cov pa roj carbon ntau dua 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%
- Yog 9-13%
- C 0.04-0.08%
- Mn 0.5-2.0%
- S 0.30% max
- 0.75% max
- P 0.03% max
- Cb/Ta 1% max
Txhua hom 347H stainless hlau uas muab los ntawm Cepheus stainless hlau, ua tau raws li cov qauv thoob ntiaj teb xws li ASTM, ASME, EN, thiab DIN.
