A corrosion- and erosion-resistant alloy for steam turbine diaphragms is described. In one example, ascast alloy poured at 2935 F had a composition of 0.04% C, 10.5% Cr, 1.49% Mn, 1.15% Ni, 0.30% Si, 0.03% Mo, and 0.01% V, bal. Fe. The casting was stress relieved 8 hr at 1200 F. The machining and welding properties of these alloys are good. The Brinell hardness of the as-cast metal was dropped from ~320 to 180 by the stress relieving. (T.R.H.)
