Kev piav txog
347h stainless hlau hlau yog lub tshuab hlau hlau ua kom muaj zog, thiab nws yog cov khoom siv hluav taws xob ua kom ruaj khov rau cov hluav taws xob, kev lag luam siv tshuaj lom neeg, aerospace thiab lwm yam. Nws cov qauv ua thiab cov kev kho kom haum rau cov kev xav tau ua tau raws li cov kev xav tau ntawm ntau theem los ntawm kev txhawb nqa kub siab rau kev txiav txim siab.

Qhov sib txawv ntawm cov sib txawv 347 stainless hlau
- Cov ntsiab lus carbon:347H muaj ntau dua cov ntsiab lus roj teeb ntau dua (0.10% vs. 0.08%) kom ua kom zoo siab kub lub zog thiab creep resistance.
- Niobium tswj:347H muaj NB / C piv txog ntau dua lossis sib npaug rau 8: 1 (piv txwv li ntawm 0.8C) kom tau raws li cov ntsiab lus niobium tsawg kawg nkaus.

Qhov sib piv nrog cov ntaub ntawv zoo sib xws
- 347h vs . 316 l:
347h Niobium ruaj khov tsim los ua kom nws kub siab tiv thaiv kom muaj kev sib txuam nrog kev txhim kho corrosion yog qhov muaj zog dua, haum rau kev siv lub scene.
- 347h vs . 316 ti:
Ob qho tib si muaj cov khoom ruaj khov (NB thiab 347h tau siab dua siab dua-kub lub zog thiab yog qhov tsim nyog rau qhov chaw siab dua-ib puag ncig.

- Thermal boiler SuperHeater thiab Rhawv Rauv Rauv Txhawb Nqa, tiv taus cov dej siab ib puag ncig.
- Sab saum toj kev txhawb nqa ntawm molten ntsev tso tsheb hlau luam, tiv taus nitrate corrosion (corrosion tus nqi ntawm tsuas yog 0.013 mm / a).
- Cov nkoj tawm tsam sab hauv txhawb nqa network, cov yeeb nkab txuas ntxiv cov hlau, tiv taus cov khoom siv muaj zog thiab cov xov xwm kub kub.
- Valve Sealing ntsiab lus los tiv thaiv kom tiv thaiv vim yog kev txhim kho corrosion.
- Connectors rau cov cav sib xyaw kom muaj cov xov hlau txhim kho cov xov hlau txhim kho cov xov hlau, tiv taus luv luv ntawm 900 degree.
- Siv thiab ua cov siab-precision Seve mesh (xws li 300 Mesh ~ 1600 mesh), siv rau cov khoom siv tshuaj sib xyaw sab nrauv lossis hluav taws xob sib xyaw.
