Dab tsi yog cov tshuaj muaj pes tsawg leeg ntawm 15CrMo alloy yeeb nkab khoom
Jan 06, 2026
15CrMo yog pearlitic low- alloy heat-cov qauv hlau tsis muaj zog raws li Suav GB tus qauv, ua raws li cov qauv tsim xws li GB/T 3077-2015, thiab sib npaug rau cov ntaub ntawv xws li A335 P12 thiab A213 T12. Vim yog qhov sib ntxiv ntawm chromium (Cr) thiab molybdenum (Mo) ua cov ntsiab lus alloying, 15CrMo alloy kav muaj qhov zoo heev -kub kev ua haujlwm, cov khoom siv kho tshuab, thiab kev ua haujlwm, ua rau lawv siv cov khoom tseem ceeb nyob rau hauv siab - qhov kub thiab txias.
Tshuaj muaj pes tsawg leeg ntawm 15CrMo Boiler Tubes
Hauv 15CrMo, "15" sawv cev rau cov ntsiab lus carbon ntawm kwv yees li 0.15%, "Cr" sawv cev rau chromium, thiab "Mo" sawv cev rau molybdenum. Nws cov tshuaj muaj pes tsawg leeg yog raws li nram no:
Cov pa roj carbon (C): 0.12% ~ 0.18%
Silicon (Si): 0.17% ~ 0.37%
Manganese (Mn): 0.40% ~ 0.70%.
Chromium (Cr): 0.80% ~ 1.20%
Molybdenum (Mo): 0.40% ~ 0.55%
Phosphorus (P): Tsawg dua lossis sib npaug rau 0.035%
Sulfur (S): Tsawg dua lossis sib npaug rau 0.025%
Main Performance thiab Applications:
Zoo Siab -Tsub Muaj Zog thiab Kev Tiv Thaiv Kub Kub: Khaws lub zog siab thiab nkag siab txawm tias nyob rau qhov kub siab (feem ntau nyob ib puag ncig 500℃- 550℃).
Kev Ua Haujlwm Zoo rau Hydrogen Corrosion: Qhia tau zoo tiv thaiv hydrogen yaig nyob rau hauv siab - kub, siab - siab hydrogen ib puag ncig.
Kev ua tau zoo heev: Muaj qhov zoo weldability thiab machinability (nco ntsoov qhov xav tau rau preheating thiab post-weld heat treatment).
Qee qhov Oxidation Resistance: Muaj qee qhov kev tiv thaiv oxidation (tev tawm) ntawm qhov kub thiab txias.
Cov cheeb tsam thov (Tswj siv nyob rau hauv siab-Tsub, Siab- Ib puag ncig siab):
Fais fab nroj tsuag Boilers: Siab- kub, siab- cov khoom siv siab xws li cov raj superheater, cov kav dej, thiab cov taub hau hauv siab - siab boilers.
Kev lag luam Petrochemical: High-kub, siab- cov kav dej siab, ntim, thiab cov khoom siv hluav taws xob hloov pauv hauv hydrogenation reactors, catalytic transforming units, thiab cracking units.
Cov Nkoj Siab: Cov plhaub, taub hau, flanges, thiab lwm yam, ntawm cov hlab ntsha siab uas yuav tsum tau ua haujlwm ntawm qhov kub thiab txias.
Chav Turbines: Cov khoom siv xws li lub tog raj kheej, diaphragms, thiab lub ntsiab chav valve.
