Qhov no steel round bar muaj ib tug tshwj xeeb alloying muaj pes tsawg leeg uas imparts nws tshwj xeeb zoo. Cov ntsiab lus chromium (Cr) hauv 12Cr1MoV muab kev txhim kho corrosion, ua rau lub voj voog puag ncig kom tiv taus qhov cuam tshuam ntawm qhov chaw sib txawv. Nws pab tsim cov txheej txheem tiv thaiv oxide rau ntawm qhov chaw, uas ua rau nws cov kav ntev thiab kev pab cuam lub neej. Qhov sib ntxiv ntawm molybdenum (Mo) tseem txhim kho cov hlau lub zog, tshwj xeeb tshaj yog thaum kub siab. Nws kuj tseem txhim khu lub hardenability thiab toughness ntawm cov khoom, ua rau nws ntau resistant rau deformation thiab tawg nyob rau hauv ntau yam loading tej yam kev mob. Lub ntsiab lus vanadium (V) ntxiv refines lub microstructure ntawm hlau, ua rau nws lub zog thiab hnav tsis kam. Nws ua lub luag haujlwm tseem ceeb hauv kev tswj cov qoob loo loj, uas yog qhov tseem ceeb rau kev ua tiav cov khoom siv kho kom zoo.
Cov txheej txheem tsim khoom ntawm 12Cr1MoV steel puag ncig tuav muaj cov txheej txheem siab heev thiab kev tswj xyuas nruj. Nws feem ntau undergoes txheej txheem xws li kub dov los yog forging kom ua tau raws li qhov xav tau txoj kab uas hla thiab microstructure. Kev kho cua sov yog ib kauj ruam tseem ceeb hauv kev tsim khoom. quenching thiab tempering feem ntau yog ua haujlwm los ua kom zoo rau cov khoom siv hluav taws xob ntawm lub voj voog puag ncig. quenching sai txias cov hlau, nce nws hardness, thiab tempering ces txo lub brittleness thiab txhim kho lub toughness thiab ductility. Kev tshuaj xyuas zoo yog ua nyob rau ntau theem kom ntseeg tau tias cov kab puag ncig ua tau raws li cov qauv tsim nyog thiab cov lus qhia tshwj xeeb.

Thaum nws los txog rau cov ntawv thov, 12Cr1MoV steel puag ncig tuav tau dav siv hauv kev lag luam tsim hluav taws xob, tshwj xeeb hauv kev tsim cov boilers, chav turbines, thiab cov cua kub exchangers. Nws muaj peev xwm tiv taus qhov kub thiab txias siab ua rau nws yog qhov kev xaiv zoo tshaj plaws rau cov ntawv thov no. Nyob rau hauv kev lag luam petrochemical, nws yog siv nyob rau hauv fabrication ntawm siab hlab ntsha, pipelines, thiab reactor Cheebtsam, qhov twg nws corrosion kuj thiab mechanical zog muaj nuj nqis heev. Tsis tas li ntawd, nyob rau hauv lub tshuab hluav taws xob engineering, 12Cr1MoV steel puag ncig tuav yog siv rau kev tsim cov ncej, lub zog, thiab lwm yam tseem ceeb uas yuav tsum tau muaj zog thiab hnav tsis kam.
Hauv kev xaus, 12Cr1MoV steel round bar yog cov khoom siv tseem ceeb hauv kev lag luam niaj hnub no. Nws qhov tshwj xeeb alloying muaj pes tsawg leeg thiab cov txheej txheem tsim khoom zoo ua rau cov khoom lag luam zoo heev uas ua tau raws li qhov xav tau ntawm ntau yam kev siv. Kev tshawb fawb txuas ntxiv thiab kev txhim kho hauv kev tsim cov hlau yuav ua rau muaj kev txhim kho ntxiv ntawm 12Cr1MoV steel puag ncig tuav thiab nthuav lawv cov chaw siv, pab txhawb rau kev nce qib thiab kev tsim kho tshiab ntawm kev lag luam sib txawv thiab ua kom muaj kev tsim kho ntau dua thiab txhim khu kev qha engineering systems thiab cov khoom siv. .
