Lub ntsiab lus ntawm GH hauv P265GH yog dab tsi?
P265GH qhia meej tias yog carbon manganese steel (C-Mn steel), uas yog nyob rau hauv qeb ntawm cov tsis yog{2}} alloy steel. Hauv nws lub npe, "P" sawv cev rau kev siv lub nkoj siab, "265" qhia qhov tsawg kawg nkaus lub zog ntawm 265 MPa, thiab "G" thiab "H" feem ntau hais txog manganese ntxiv dag zog thiab siab - qhov kub thiab txias.
ASTM sib npaug ntawm P265 GH yog dab tsi?
Tuam Tshoj (GB): 20G (Boiler steel, GB 713).
Teb Chaws Asmeskas (ASTM): SA-516 Gr.60/65 (Similar yield zog).
P265GH khoom yog dab tsi?
P265GH steel yog lub siab - lub zog, qis- alloy structural steel khoom ntawm European tus qauv, uas muaj cov yam ntxwv ntawm kev tswj cov khoom zoo ntawm qhov kub thiab txias zoo heev - kub toughness.
P265GH tshuaj muaj pes tsawg leeg
Cov tshuaj muaj pes tsawg leeg ntawm P265GH steel phaj feem ntau suav nrog cov ntsiab lus xws li carbon (C), silicon (Si), manganese (Mn), phosphorus (P), thiab sulfur (S), nrog rau cov ntsiab lus tshwj xeeb raws li hauv qab no:
Carbon (C): Tsawg dua lossis sib npaug li 0.20%
Silicon (Si): Tsawg dua lossis sib npaug li 0.40%
Manganese (Mn): 0.80% -1.40%
Phosphorus (P): Tsawg dua lossis sib npaug rau 0.025%
Sulfur (S): Tsawg dua lossis sib npaug rau 0.010%
Tsis tas li ntawd, nws kuj tseem muaj cov ntsiab lus alloying xws li chromium (Cr), npib tsib xee (Ni), molybdenum (Mo), niobium (Nb), vanadium (V), aluminium (Al), thiab tooj liab (Cu), tab sis cov ntsiab lus raug txwv; Piv txwv li, chromium (Cr) thiab npib tsib xee (Ni) yog ob qho tib si tsawg dua lossis sib npaug li 0.30%.
P265GH Lub cev muaj zog
Tensile zog: 410-530 MPa
Yield zog: Ntau dua lossis sib npaug li 260 MPa
Elongation: Txog li 22%
P265GH steel, vim nws cov yam ntxwv ua tau zoo heev, yog siv dav hauv ntau qhov chaw:
Kev tsim cov nkoj siab: xws li boilers, cia tank, petrochemical khoom, thiab lwm yam.
Thaum tshav kub kub exchangers: manufacturing tshav kub exchanger plhaub thiab raj bundles.
Boiler piping: haum rau kev tsim ntau hom boiler piping systems.
Kev lag luam roj thiab roj: cov cuab yeej tsim khoom siv roj thiab roj rho tawm, kev thauj mus los, thiab kev ua haujlwm.
Fais fab kev lag luam: boiler thiab siab nkoj tsim rau fais fab nroj tsuag.
Shipbuilding thiab marine engineering: cov khoom siv zoo tshaj plaws rau lub nkoj hull cov qauv, marine piping, thiab lwm yam.
Kev tsim kho choj: nws lub zog siab thiab zoo weldability ua rau cov qauv choj muaj zog thiab ruaj khov.
Lwm yam kev lag luam: xws li aerospace, automotive, thiab kev tsim kho tshuab.
