Title
Effects of Cobalt and boron on the Mechanical and Corrosive Properties of nickel free Austenitic Stainless Steel
천병선Byung Sun Chun, 김동훈Tong Hoon Kim
Abstract
Four kinds of alloy, Fe-18%Mn-14%Cr-2%Co, Fe-18%Mn-14%Cr-4%Co, Fe-17%Mn-14%Cr-4%Ni and Fe-17%Mn-14%Cr-2%Co-B. were prepared in air by means of a high frequency induction furnace. Then the mechanical and corrosive Properties of these alloys were studied, being compared with those of 18-8 stainless steel. It is concluded that the mechanical properties and corrosion resistance of the cobalt alloy increase with cobalt is replaced by boron, the two properties of the alloy can also be improved greatly as those of the alloy having cobalt.
