25Cr2MoVA kub dov steel ntawv

① Ob tug lej ntawm qhov pib ntawm tus lej hlau qhia cov ntsiab lus ntawm cov hlau, qhia hauv kaum-txhiab ntawm cov ntsiab lus nruab nrab ntawm cov pa roj carbon monoxide, xws li 40Cr, 25Cr2MoVA alloy raj.
② Lub ntsiab alloying ntsiab nyob rau hauv steel, tshwj tsis yog rau ib tug neeg microalloying ntsiab, feem ntau qhia nyob rau hauv ob peb feem pua. Thaum qhov nruab nrab cov ntsiab lus alloy tsawg dua 1.5%, feem ntau tsuas yog lub cim cim qhia nyob rau hauv tus lej steel, thiab cov ntsiab lus tsis qhia. Txawm li cas los xij, nyob rau hauv cov xwm txheej tshwj xeeb, nws yooj yim ua rau tsis meej pem, thiab tus lej "1" kuj tuaj yeem raug cim tom qab lub cim cim, xws li steel tooj "12CrMoV" thiab "12Cr1MoV", tus qub muaj cov ntsiab lus chromium ntawm 0.4-0.6. %, tom kawg muaj cov ntsiab lus chromium ntawm 0.9-1.2%, thiab tus so yog tib yam. Thaum cov ntsiab lus nruab nrab ntawm cov ntsiab lus alloying yog ≥1.5%, ≥2.5%, ≥3.5% ..., cov ntsiab lus yuav tsum tau qhia tom qab lub cim cim, uas tuaj yeem qhia tau tias yog 2, 3, 4 ... thiab lwm yam. Piv txwv li. , 18Cr2Ni4WA.
③ Alloying ntsiab xws li vanadium V, titanium Ti, txhuas AL, boron B, thiab tsawg ntiaj teb RE nyob rau hauv hlau yog tag nrho cov microalloying ntsiab. Txawm hais tias cov ntsiab lus tsawg heev, lawv tseem yuav tsum tau cim rau hauv tus lej steel. Piv txwv li, hauv 20MnVB steel. Vanadium yog 0.07-0.12%, thiab boron yog 0.001-0.005%.
④High-qib siab zoo steel yuav tsum ntxiv "A" tom kawg ntawm tus lej steel kom paub qhov txawv ntawm cov hlau zoo.
⑤ Lub hom phiaj tshwj xeeb alloy cov qauv steel, tus lej steel yog ua ntej (los yog suffixed) nrog lub cim sawv cev rau lub hom phiaj ntawm cov hlau. Piv txwv li, 30CrMnSi steel tshwj xeeb rau riveting screws, steel tooj yog qhia raws li ML30CrMnSi.
Alloy kav thiab seamless kav yog ob qho tib si muaj feem xyuam thiab sib txawv, thiab yuav tsum tsis txhob totaub.
Alloy yeeb nkab yog txhais los ntawm cov yeeb nkab steel raws li cov khoom siv (uas yog, cov khoom siv), raws li lub npe implies, yog cov yeeb nkab ua los ntawm alloy; hos seamless yeeb nkab yog txhais los ntawm steel yeeb nkab raws li cov txheej txheem ntau lawm (seamless thiab seamless), qhov txawv ntawm seamless yeeb nkab yog Seam kav, nrog rau ncaj seam welded kav thiab kauv kav.
