P235GH thiab P265GH yog ob qho tib si tsis yog - alloy steels rau cov hlab ntsha siab, tab sis P265GH muaj lub zog ntau dua, nrog rau qhov tsawg kawg nkaus lub zog ntawm 265 MPa, piv rau P235GH's 235 MPa, ua rau nws tsim nyog rau siab dua - cov ntawv thov siab, thaum P235GH muaj cov ntsiab lus zoo dua rau cov ntsiab lus qis dua. 0.16% vs. P265GH yog ~ 0.20%). Ob leeg sib koom siab zoo sib xws - kub siv tab sis txawv ntawm lub zog, nrog P265GH yog qhov muaj zog dua, "siab dua-qib" xaiv rau cov kev xav tau.
Tshuaj muaj pes tsawg leeg
Mechanical Properties
P235GH: Muaj qhov tsawg kawg nkaus tawm lub zog ntawm 235 MPa, ua rau nws haum rau nruab nrab - kev siv siab. Nws lub zog tensile thaj tsam ntawm 360-500 MPa.
P265GH: Muab lub zog tawm los ntau dua ntawm 265 MPa thiab lub zog tensile ntawm 410-570 MPa, muab kev ua haujlwm zoo dua hauv qhov chaw siab dua.
Cov qauv sib npaug
Daim ntawv thov
P235GH:
Vim nws zoo heev weldability thiab nruab nrab lub zog, P235GH feem ntau siv nyob rau hauv:
Kub exchangers
Tsawg-siab boilers
Cov kav dej rau cov kua dej lossis cov pa roj uas muaj qhov siab thiab qhov kub thiab txias
P265GH:
Nrog nws lub zog zoo dua, P265GH yog qhov zoo tagnrho rau kev thov ntau dua, xws li:
High-siab boilers
Cov hlab ntsha siab
Industrial pipelines nqa high -kub kua
Weldability thiab Fabrication
P235GH: Yooj yim rau vuam vim nws cov ntsiab lus qis dua, ua rau nws yog qhov kev xaiv zoo tshaj plaws rau cov haujlwm uas vuam ntau zaus.
P265GH: Tseem weldable tab sis yuav tsum tau preheating lossis lwm yam kev ceev faj vim nws cov pa roj carbon ntau dua.
