11MnNiMoDR yog ib lub phaj hlau rau qhov kub thiab txias siab nrog rau qhov kub thiab txias: -70 degree . Kev ua raws li GB713-2014 tus qauv. Lub ntsiab lus "R" hauv qib yog hais txog tus pinyin pib ntawm "Rong" rau lub nkoj siab, 11 txhais tau tias cov ntsiab lus carbon yog 0.11%, thiab Mn, Ni, Mo hauv qib txhais tau hais tias cov tshuaj cov ntsiab lus manganese, nickel, molybdenum cov ntsiab lus yog siab. 11MnNiMoDR steel phaj yog melted los ntawm cov pa saum toj-blowing converter txoj kev, ca rauv txoj kev los yog nyob rau hauv hluav taws xob rauv. Oxygen top-blowing converter method, ca rauv txoj kev los yog melting nyob rau hauv hluav taws xob rauv. Lwm txoj hauv kev sib npaug kuj tuaj yeem siv tom qab kev sib tham nrog cov neeg thov.
Cov pa roj carbon monoxide yog ib qho tseem ceeb ntawm 11MnNiMoDR steel phaj, uas tuaj yeem txhim kho qhov nyuaj thiab lub zog ntawm cov phaj steel, tab sis cov pa roj carbon ntau dhau yuav txo qhov toughness thiab weldability ntawm steel phaj. Silicon tuaj yeem txhim kho lub zog thiab tawv ntawm cov phaj hlau thiab feem ntau yog siv los ua deoxidizer hauv kev tsim khoom. Manganese yog ib qho tseem ceeb ntawm cov hlau alloying uas tuaj yeem txhim kho lub zog thiab kub tsis kam ntawm cov hlau phaj. Phosphorus thiab sulfur tsis tshua muaj txiaj ntsig rau cov phaj steel, tab sis ntau dhau ntawm phosphorus thiab sulfur yuav txo qhov kev ua haujlwm thiab weldability ntawm steel phaj.
11MnNiMoDR steel phaj nws tus kheej muaj cov khoom zoo xws li lub zog siab, tsis kub tsis kam, cuam tshuam tsis kam, ua haujlwm tsis zoo, corrosion kuj, qaug zog tsis kam, siab toughness, compression kuj thiab vuam yooj yim ntawm kev ua.
