15CrMoR steel phaj yog ib hom qis carbon alloy steel phaj nrog lub zog siab, corrosion kuj thiab kub tsis tshua muaj kev cuam tshuam kev ua haujlwm, uas yog dav siv hauv roj av, tshuaj, hluav taws xob, hluav taws xob nuclear thiab dej hiav txwv engineering.
Cov tshuaj muaj pes tsawg leeg ntawm 15CrMoR steel phaj feem ntau suav nrog hlau, carbon, chromium, manganese, silicon thiab ib qho me me ntawm alloying ntsiab. Ntawm lawv, cov ntsiab lus carbon yog 0.12% rau 0.20%, chromium cov ntsiab lus yog 0.80% rau 1.2{{ 13}}%, manganese cov ntsiab lus yog 0.40% rau 0.70%, thiab cov ntsiab lus silicon yog 0.20% txog 0.50%. Kev sib xyaw ua ke ntawm cov ntsiab lus no muaj kev cuam tshuam tseem ceeb ntawm cov khoom siv kho tshuab thiab corrosion kuj ntawm cov khoom.
15CrMoR steel phaj muaj lub zog siab thiab zoo toughness. Nws lub zog tawm los thiab lub zog tensile yog 800MPa thiab 900MPa feem, thiab nws qhov nyuaj ntawm 24HRC txog 32HRC. Tsis tas li ntawd, nws cov cuab yeej cuab tam indexes xws li elongation, cuam tshuam toughness, seem shrinkage thiab dabtsi yog khoov txwv yog zoo heev, uas muaj peev xwm ua tau raws li cov kev xav tau ntawm ntau yam complex engineering lug.
Nyob rau hauv ib puag ncig corrosive, qhov saum npoo ntawm 15CrMoR steel phaj tsim cov oxide zaj duab xis ntom ntom, uas tiv taus oxidation thiab corrosion tawm tsam. Tsis tas li ntawd, cov khoom no qhia tau hais tias zoo corrosion kuj nyob rau hauv ntau yam organic thiab inorganic corrosive media, xws li dej, nitric acid, acetic acid thiab hais txog. Qhov no ua rau 15CrMoR muaj lub neej ua haujlwm ntev hauv roj av, tshuaj lom neeg thiab lwm yam kev lag luam.
