Qib Tp347 Stainless hlau yog niobium -} stabilized ustenitic steel hlau. Qhov sib ntxiv ntawm Niobium inhibits chomium carbide nag lossis txhawb nqa cov qauv gravacation, txhim kho cov qauv gravacion, txhim kho kom muaj kev cuam tshuam daws teeb meem, thiab txhawb kev ua kom tawv nqaij. Chemically, SS347 tuaj yeem suav hais tias yog kev hloov kho ntawm304 Stainless Hlaunrog kev sib ntxiv ntawm niobium.
Qib TPA47H Stainless Hlau yog lub siab-} carbon version ntawm Tp347. Ob qib yog tsim nyog rau high - huab cua kev ua haujlwm nyob rau hauv ntau ntawm 450℃mus rau 850 degree.

Key Niobium Thiab Carbon Cov Ntsiab Lus
Raws li muaj nyob hauv daim duab hauv qab no, TPP47 muaj cov ntsiab lus muaj roj carbon ntau dua Tp347H.
Ob qib kawm tau ruaj khov los ntawm niobium. Niobium sib xyaw nrog cov pa roj carbon los ua cov pa niobium carbides, tiv thaiv chromium depetion ntawm cov ciaj ciam nplej. Qhov no tswj hwm cov khoom siv cov khoom lag luam tiv thaiv kab mob thaum muaj siab lossis siab}}} kev pabcuam kub (800℃-816 degree).
Cov Cuab Yeej Siv Cov Neeg Kho Tshuab ntawm ASTM A312 / 347H
Raws li ATM A312 cov lus qhia tshwj xeeb, chav sov cov khoom kub cov khoom ntawm TPp347 thiab TPR47H yog qhov zoo tib yam. Cov ntsiab lus muaj roj carbon ntau dua tsis hloov hloov lub ambient kub ductility ntawm Tp347H.
Lub zog tensile: 75 [515]
Yield zog: 30 [205]
Elongation nyob rau hauv 50 hli:
-} ntev ntev 35%
- transverse25%
TPP347 Cov khoom pov thawj zoo dua siab siab - kub} kev ua haujlwm kub. Vim nws cov ntsiab lus carbon ntau, nws pom tau zoo dua creep lub zog thiab kev ntxhov siab tsis kam nyob hauv qhov kub ntawm 427℃rau 816 degree.
Tp347 vs Tp347h raug nqi sib txawv
Nyob rau hauv cov nqe lus ntawm tus nqi,Teng47H feem ntau kim dua Tp347, feem ntau yog vim nws cov kev tswj hwm cov me nyuam roj carbon monoxide thaum tsim khoom.

Kev kho tshav kub ntawm Tp347HH ip p
Annealing Kub ntau yam: 1800 Degree F rau 2000℃F (982 Qib rau 1093 degree).
Kev Txhaum Kev nyuaj siab ntxhov siab tuaj yeem ua rau hauv cov carbide los nag Ze 800 Qib F [416℃rau 816℃rau 816 degree] tsis muaj kev pheej hmoo ntawm kev sib txuam ntawm kev sib txuam.
Tsis tuaj yeem ua tsis tau zoo los ntawm kev kho cua sov.
