Abstract
A pulser ring made of a ferritic iron alloy with the following composition (in wt. %) max. 0.12% C, max. 1.00% Si, max. 1.00% Mn, max. 0.045% P, max. 0.030% S and max. 18% Cr, with the rest being iron with impurities conditional upon the melting process and a method of heat treating the same.
Claims3
