Study of a New Type Austenitic Stainless Steel with Better Wear Resistance

To solve the problem that traditional austenitic stainless steels have poor wear resistance,a new type of Fe-Mn-Si-Cr-Ni-C austenitic stainless steel was designed and its properties of wear and corrosion were studied.Fe-Mn-Si-Cr-Ni-C austenitic stainless steel exhibited better wear resistance than 1Cr18Ni9Ti steel did both in dry friction and oil lubrication.Fe-Mn-Si-Cr-Ni-C austenitic stainless steel exhibited better wear resistance than 1Cr18Ni9Ti steel did in NaOH solution,but poor in NaCl solution.Stress-induced γ→e martensitic phase transformation of new Fe-Mn-Si-Cr-Ni-C austenitic stainless steel during friction resulted in better wear resistance.
