15CrMoR siab lub nkoj steel phaj yog siv dav hlau phaj rau cov hlab ntsha uas tsis tshua muaj siab, uas yog siv dav hauv roj av, tshuaj, hluav taws xob, tshuaj thiab lwm yam haujlwm. Vim nws cov khoom siv zoo heev, kev tiv thaiv corrosion thiab vuam kev ua tau zoo, nws yog dav siv nyob rau hauv kev tsim khoom ntawm ntau yam siab hlab ntsha, tso tsheb hlau luam, kav dej thiab lwm yam khoom siv.
Cov tshuaj muaj pes tsawg leeg ntawm 15CrMoR steel phaj yog tsim los ntawm hlau, chromium, carbon, manganese, silicon thiab lwm yam khoom. Ntawm lawv, cov ntsiab lus chromium yog siab dua, nrog zoo corrosion kuj; carbon cov ntsiab lus qis dua, ua kom cov vuam zoo; thaum ntxiv ib qho tsim nyog ntawm manganese thiab silicon ntsiab los txhim kho lub zog thiab toughness ntawm steel phaj.
Cov khoom siv kho tshuab ntawm 15CrMoR steel phaj feem ntau suav nrog lub zog tensile, lub zog tawm los, elongation thiab cuam tshuam ua haujlwm. Ntawm lawv, lub zog tensile thiab lub zog tawm los yog qhov tseem ceeb ntsuas ntsuas cov khoom siv ntawm cov hlau phaj, thaum elongation thiab cuam tshuam kev ua haujlwm cuam tshuam txog cov yas thiab tawv ntawm steel phaj.15CrMoR steel phaj lub zog tensile feem ntau yog siab tshaj 490MPa, yield zog yog li 310MPa, elongation yog ntau tshaj 20%, nrog zoo plasticity thiab toughness.
Vim tias 15CrMoR steel phaj muaj cov khoom siv zoo heev, kev tiv thaiv corrosion thiab vuam kev ua tau zoo, nws yog dav siv hauv roj av, tshuaj, hluav taws xob, tshuaj thiab lwm yam haujlwm. Piv txwv li, hauv kev lag luam roj av, 15CrMoR steel phaj tuaj yeem siv rau hauv kev tsim cov roj tank, roj kav dej thiab lwm yam khoom siv; hauv kev lag luam tshuaj, nws tuaj yeem siv rau hauv kev tsim cov reactors, distillation yees thiab lwm yam khoom siv; hauv kev lag luam hluav taws xob hluav taws xob, nws tuaj yeem siv rau hauv kev tsim cov boilers, siab hlab ntsha thiab lwm yam khoom siv; hauv kev lag luam kws tshuaj, nws tuaj yeem siv rau hauv kev tsim cov khoom siv tshuaj thiab lwm yam.
