Cov tshuaj muaj pes tsawg leeg ntawm 14Cr1MoR steel phaj yuav tsum ua raws li cov qauv tsim nyog. Nws cov tshuaj tseem ceeb muaj xws li hlau, carbon, silicon, manganese, phosphorus, sulfur thiab lwm yam khoom. Ntawm lawv, cov pa roj carbon yog ib qho tseem ceeb uas cuam tshuam rau lub zog thiab lub zog ntawm cov hlau phaj, silicon thiab manganese tuaj yeem txhim kho lub zog thiab hardness ntawm cov hlau phaj, thiab phosphorus thiab sulfur yog ib qho tseem ceeb uas cuam tshuam rau qhov toughness thiab corrosion kuj ntawm cov hlau. phaj. Tsis tas li ntawd, 14Cr1MoR steel phaj kuj muaj qee yam ntawm chromium thiab molybdenum cov ntsiab lus, uas tuaj yeem txhim kho corrosion kuj thiab kub siab zog ntawm steel phaj.
Cov khoom siv kho tshuab ntawm 14Cr1MoR steel phaj yuav tsum ua raws li cov kev cai ntawm Table 1. Nws lub zog tensile thiab yield zog siab, thiab nws elongation thiab cuam tshuam kev ua haujlwm kuj zoo. Cov yam ntxwv ntawm cov khoom siv kho tshuab no tuaj yeem ua kom ntseeg tau tias cov phaj hlau muaj kev ruaj ntseg thiab kev ntseeg siab thaum nws raug kub, siab siab, corrosion thiab lwm yam hnyav hnyav thiab loads. Nyob rau tib lub sijhawm, 14Cr1MoR steel phaj kuj muaj qhov zoo ntawm qhov kub thiab txias thiab tiv thaiv kev qaug zog, thiab tuaj yeem tswj kev ua haujlwm ruaj khov nyob rau hauv qhov kub thiab txias.
14Cr1MoR steel phaj muaj qhov zoo corrosion kuj thiab tuaj yeem siv tau ntev hauv qhov chaw hnyav xws li kub, siab siab thiab corrosion. Qhov no feem ntau yog vim nws cov tshuaj muaj pes tsawg leeg thiab txheej txheej. Nyob rau hauv chav tsev kub, steel phaj muaj corrosion kuj zoo nyob rau hauv qhuav thiab ntub ib puag ncig. Nyob rau hauv qhov kub thiab txias, steel phaj yuav tsum muaj oxidation zoo thiab corrosion kuj. Tsis tas li ntawd, cov phaj hlau yuav tsum muaj kev qaug zog zoo thiab kev cuam tshuam los ua kom muaj kev ruaj ntseg zoo thiab kev ntseeg siab hauv kev siv mus ntev. Cov yam ntxwv tiv thaiv corrosion no ua rau 14Cr1MoR steel phaj tuaj yeem hloov mus rau ntau qhov chaw nyob hauv qab cov khoom tsim khoom.
