Corrosion resistant austenitic alloy
Creators
Description
An austenitic stainless corrosion resistant alloy and articles made therefrom having good resistance to pitting and crevice corrosion in oxidizing chloride-bearing media combined with resistance to general corrosion and to intergranular corrosion in oxidizing media containing C, Mn, Si, P, S, Cr, Ni, Mo, Cu, N, B, Ce, La, Nb, Ti and the balance iron. The amount of nitrogen is not greater than that which can be retained in solution. When present niobium plus titanium ranges upward from a minimum which is sufficient to combine stoichiometrically with the amount of carbon present in excess of 0.025 w/o. In this composition the elements chromium, nickel, molybdenum and copper are balanced so that the value of Correlation I is equal to or less than 1.6021 and that of Correlation II is equal to or less than 5
