Dab tsi yog qhov txawv ntawm P11 thiab P22 khoom
Jan 07, 2026
A335P11 thiab A335P22 yog ob hom chromium-molybdenum alloy steel kav hauv Asmeskas tus qauv ASTM A335. Qhov sib txawv tseem ceeb yog nyob rau hauv lawv cov tshuaj muaj pes tsawg leeg thiab siv tau qhov kub thiab txias.
Chemical Composition Differences:
A335P11: Chromium ntsiab lus 1.00% -1.50%, Molybdenum ntsiab lus 0.44% -0.65%
A335P22: Chromium ntsiab lus 1.90% -2.60%, Molybdenum ntsiab lus 0.87% -1.13%
P22 muaj cov ntsiab lus chromium thiab molybdenum ntau dua, ua rau muaj zog dua -kub tsis kam.
Mechanical Properties Sib piv
Ob leeg muaj cov khoom siv zoo sib xws, xav tau lub zog tensile Ntau dua lossis sib npaug ntawm 415MPa, lub zog tawm los Ntau dua lossis sib npaug ntawm 205MPa, thiab elongation Ntau dua lossis sib npaug li 30%. Txawm li cas los xij, P22, vim nws cov ntsiab lus ntawm cov hlau alloy ntau dua, ua rau pom lub zog zoo dua ntawm qhov kub thiab txias.
Daim ntawv thov Scenario
A335P11: Haum rau nruab nrab - thiab siab - qhov chaw siab nrog qhov kub thiab txias tsawg dua lossis sib npaug li 540 degree, xws li boiler superheaters thiab cov kav dej.
A335P22: Tshwj xeeb tsim rau siab - kub thiab siab - cov ntawv thov siab, nrog rau kev khiav hauj lwm kub txog li 580℃thiab siab tshaj los yog sib npaug rau 9.8MPa. Feem ntau siv nyob rau hauv fais fab nroj tsuag boilers thiab siab -kub piping systems nyob rau hauv lub petrochemical kev lag luam.
Cov qhab nia sib npaug hauv tsev
A335P11 sib raug rau qib 12Cr1MoVG hauv tsev.
A335P22 sib raug rau qib 12Cr2MoG hauv tsev.
