Dab tsi yog qhov muaj pes tsawg leeg ntawm SA514 qib F?
SA514 Qib Fyog lub siab -lub zog, quenched thiab tempered alloy steel phaj, paub txog nws lub zog tshwj xeeb - rau - qhov hnyav piv thiab toughness. Nws yog feem ntau siv rau hauv kev thov cov txheej txheem kev siv qhov twg qhov hnyav txuag thiab kav ntev yog qhov tseem ceeb.
Cov khoom siv SA514 Qib F yog dab tsi?
SA514 Qib F yog siab -lub zog, quenched thiab tempered alloy steel phaj (ASTM A514 Qib F / ASME SA514 Qib F) paub txog nws lub zog zoo heev (min 100 ksi), toughness, thiab zoo weldability, siv nyob rau hauv hnyav structural daim ntaub ntawv xws li kev tsim kho cov cuab yeej, {6} thav duab hnyav, thiab - lub zog ntawm cov khoom siv, cov khoom siv cranes, thiab - hnyav npaum li cas. tseem ceeb heev. Nws ua tiav nws cov khoom los ntawm cov txheej txheem kho cua sov ntawm quenching thiab tempering thiab muaj cov ntsiab lus alloying xws li Nickel, Chromium, Molybdenum, thiab tooj liab rau kev ua tau zoo.

Hauv cov ntsiab lus,SA514 Qib F yog ib qho sophisticated, boron - kho, quenched thiab tempered alloy steel txhais los ntawm nws 100 ksi (690 MPa) yam tsawg kawg nkaus yield zog thiab zoo heev toughness. Nws ua tib zoo sib npaug sib npaug ntawm C, Mn, Cr, Mo, V, thiab B ua rau nws yog qhov kev xaiv tseem ceeb rau qhov tseem ceeb, qhov hnyav- cov qauv rhiab heev hauv kev lag luam hnyav.
1. Dab tsi yog SA36 steel feem ntau siv rau?
SA36 yog qhov dav siv dav tshaj plaws - lub hom phiaj cov qauv hlau hauv North America, feem ntau ua haujlwm hauv lub tsev thav duab, txuas hniav, cov cuab yeej siv hauv tsev, thiab kev tsim khoom dav dav uas yuav tsum muaj lub zog nruab nrab thiab zoo weldability.
2. Lub zog ntawm SA36 steel yog dab tsi?
SA36 muaj qhov tsawg kawg nkaus tawm lub zog ntawm 36,000 psi (250 MPa), uas yog lub hauv paus rau nws lub npe ("36") thiab ua rau nws haum rau ntau yam ntawm cov qauv siv.
3. Puas yog SA36 steel weldable?
Yog lawm, SA36 yog weldable heev siv txoj kev zoo li SMAW, GMAW, thiab FCAW. Txawm li cas los xij, preheating tej zaum yuav tsim nyog rau cov seem tuab los yog cov pob qij txha uas tsis muaj zog vim nws cov ntsiab lus carbon tsis sib xws.
4. SA36 txawv ntawm SA572 Qib 50 li cas?
SA36 muaj lub zog qis dua (36 ksi vs . 50 ksi) thiab yog cov pa roj carbon steel, thaum SA572 Qib 50 yog siab - zog qis- alloy (HSLA) steel nrog lub zog zoo dua - rau - qhov hnyav piv thiab atmospheric corrosion kuj.
Tag nrho cov specification thiab cov ntsiab lus muaj nyob rau ntawm kev thov. Cov ntaub ntawv saum toj no yog muab rau kev taw qhia nkaus xwb. Rau kev tsim tshwj xeeb thov hu rau peb cov neeg ua haujlwm muag khoom.
