P23 khoom yog dab tsi
Feb 06, 2026
A335 P23yog chromium-molybdenum alloy steel yeeb nkab raws li tus qauv ASTM A335, nrog cov tshuaj muaj pes tsawg leeg ntawm 1.25Cr-0.5Mo-V-Nb-N (UNS K11547). Piv nrog rau cov khoom siv P22 ib txwm muaj, P23 txhim kho qhov kub thiab txias zog thiab oxidation tsis kam los ntawm kev ntxiv microalloying ntsiab xws li vanadium (V), niobium (Nb), thiab nitrogen (N).
Nws cov cuab yeej siv tau zoo yog: chav tsev kub tensile zog Ntau dua los yog sib npaug rau 510MPa, yield zog Ntau dua los yog sib npaug rau 400MPa, thiab zoo heev creep rupture zog txawm nyob rau ntawm 600 degree. Cov khoom no ua tau raws li cov qauv thoob ntiaj teb xws li ASME SA-335 thiab EN 10216-2, thiab tau dhau PED 2014/68 / EU Cov Khoom Siv Siab Cov Ntawv Qhia, ua rau nws tsim nyog rau qhov chaw hnyav nrog kev ua haujlwm kub ntawm -10℃txog 625 degree.
GNEE Group yog cov chaw tsim khoom hauv cov yeeb nkab steel hauv Suav teb, muab cov yeeb nkab kev sib tham thiab kev ua haujlwm.Dawb 1-2 meter kuaj xa tuaj, freight sau -yog tias koj xaj hauv 30 hnub, tus nqi coj mus kuaj raug txiav tawm.
