1. Cov khoom no yog dab tsi?
07cr25ni2ni2ni2ni2nnn yog qhov siab {{3} {ove {{istant stainless hlau tsim rau siv nyob rau hauv high-}} kub ib puag ncig. Nws cov ntsiab lus tseem ceeb yog chromium (25%) thiab npib tsib), nrog niobium (n) ntxiv rau txhim kho siab {} qhov kub thiab txias. Cov qib siab zoo sib xws xws li ASTM A213 TP310THNBN, thiab cov qauv hauv tsev laus yog 0cr25ni21nbn (GB / T 20878).
2. Dab tsi yog nws cov chaw tseem ceeb?
Ultra - high-}}}}}}}}}}}}}} Cov khoom siv luv luv xws li cov khoom siv cua sov thiab cov khoom siv kub.
Oxidation thiab corrosion Kuj: cov neeg chromium thiab npib tsib xee cov ntsiab lus tsis txaus ntseeg, ua rau muaj kev tiv thaiv carbide, ua rau muaj kev tiv thaiv carbide
Mechanical zog: nitrogen dolution zog ua tau zoo nyob rau hauv tseem zoo tshaj li superpys high zoo li lub zog sib piv rau cov qauv 310 stainless.
3. Cov ntawv thov raug?
Kev Lag Luam Zog: Ultra -} supercritical fais fab tsob nroj tshob Boiles
Petrochemical Kev Lag Luam: Ethylene Dumning Rauv Tubes, Siab - kub piping rau cov tshuaj hloov kho tshiab.
Cov Khoom Siv Cua Sov: Annealing Rauv Cov Pollers, siab- qhov kub} qhov kub thiab txias Kiln Lilnings.
4. Nws txawv li cas ntawm tus qauv 310)?
07cr25ni2ni2ni2ni2ni2ni2nnn tseem ceeb hloov kho nws qhov siab-} Lub zog ntawm kev sib txuas ntawm cov kev sib txuas (kwv yees li 1000 degree) rau ntev- siv. Tsis tas li ntawd, 07cr25ni2ni2ni2ni2nbn muaj cov weldility zoo dua, tshem tawm cov kev xav tau ntawm Post {}} Weld kev kho cua sov.
5. Ua thiab muaj peev xwm txiav txim siab
Tus qauv ntawv pov thawj: Xav paub cov kav dej hlau ua haujlwm rau Astm A213 lossis GB / T 5310 kom paub meej tias kev nyab xeeb hauv qhov siab- Siab} Lub siab} Lub Siab Boiler.
Welding txheej: Vuam cov kev siv vuam muaj niobium (xws li enicrfe-7) yog pom zoo, nrog kev ntsuas kub tsawg dua lossis sib npaug ntawm 150 degree.
Kev kuaj sim: Siab {- kub tensile kuaj (loj dua los yog sib npaug ntawm kev ntsuas (ttm A262-E), thiab cov ntawv ceeb toom ultrasonic.
