Peb AVTM A312 UNRICS S34700 STEEL STEEL YOG NIOBIUM {2} Tus qauv siv hluav taws xob tshwj xeeb tau tsim los kom xa cov kev ua tau zoo hauv cov kev ua tau zoo hauv kev ua kom haum. Nrog rau superior tsis kam rau intergranular corrosion thiab oxidation, cov kav dej offperform txheem stainless hlau stainless hlau stainless hlau stainless hlau states los ntawm 800℃f (427℃rau 816 degree). Zoo meej rau Aerospace, kev ua yeeb yam, thiab cov ntawv thov hluav taws xob uas muaj kev ntseeg tau yog qhov tseem ceeb.
Cov Nta Tseem Ceeb & Zoo
Superior high - kub ua tau zoo
Niobium ruaj khov muab kev tiv thaiv zoo heev rau intergranular corrosion ntawm 800℃f thiab 1500℃f (416 degree)
Oxidation tsis kam
Oxidation zoo heev tiv taus 1600℃f (871 degree)
Crep Lub Zog
Zoo tshaj plaws creep thiab kev nyuaj siab tawg rog ntawm kev nce kub
Hwj txwv
Cov yam ntxwv zoo dua uas tsis muaj lub ntsiab lus - Weld Kev Kho Tshav Kub Cua sov

Cov FAQ
Q: Dab tsi yog qhov tseem ceeb kom zoo dua ntawm 347 dhau 321 stainless hlau?
A: 347 siv Niobium stabilization ntau dua li titanium, muab zoo dua siab- lub zog thiab txhim kho kom muaj qee qhov chaw muaj kev sib zog.
Q: Qhov ntau tshaj plaws kub yuav 347 kav walland?
A: Kev pabcuam txuas ntxiv mus txog 1500℃f (816 degree), nrog cov kev pabcuam sib quas ntus rau 1600℃f (871 degree) rau luv luv.
Q: Puas yog koj cov pipes raws nrog ASME boiler thiab siab vessel code?
A: Yog, peb cov kav dej 347 kom ua raws li Semme ntu Virii yuav tsum muaj rau cov khoom siv siab vessel.
