Discussion F. EBERLE. 3 This paper fills a need which is felt by all who are concerned with materials for steam-plant application. The increases in steam temperatures and pressures which have taken place in recent years demand new materials, materials stronger than those standardized in the Boiler Code. In anticipation of this need, the writer's company undertook the development of a "lean superstrength alloy," an alloy as low as possible in chromium and nickel, and in strategic elements, yet
