65Mn steel phaj yog ib hom high-strength steel phaj, nws cov ntsiab lus manganese yog li ntawm 0.65%, nrog zoo hardenability thiab toughness, lug siv nyob rau hauv tsheb, machinery, tsim, shipbuilding, petrochemical thiab lwm yam teb.
65Mn steel phaj muaj lub zog tensile siab thiab lub zog tawm los, nws lub zog tensile feem ntau yog ntau tshaj 600MPa, lub zog tawm los feem ntau yog li 350MPa. Qhov kev ua tau zoo ntawm lub zog no ua rau 65Mn steel phaj tuaj yeem tiv taus cov khoom loj thiab kev kub ntxhov, thiab muaj kev ruaj ntseg zoo.
