View Sample Alloy Digest Data Sheet (PDF)Since 1952, Alloy Digest has been the leading reference for materials property data on metals and alloys used throughout the world. Featuring graphs, charts and tables, these sheets give facts and figures on composition or characterization, physical and mechanical properties, heat treatment, and machinability.SICROMO - 9M is a chromium-molybdenum, low-carbon alloy steel having good corrosion resistance and high temperature strength. It is recommended for still tubes and piping in oil refineries, heat exchanger and super-heater tubes when a greater degree of corrosion resistance is required than provided by Type 4-6 Cr-Mo steel and Sicromo 7.
