A user has requested the addition of a new grade to A240/A340M. The new grade is an austenitic stainless steel alloy with the nominal composition of 26 Cr-17.5 Ni-0.2 N-La-Ce, and its expected application is for heat exchangers and components in fuel cell units, thermal power plants, and chemical plants up to temperatures of 1000C [1832F]. A concurrent action is being proposed for A480/A480M.
