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.KHR 35CT HiSi is a modification of KHR 35C HiSi (see Alloy Digest SS-753 and SS-755) by the addition of both silicon and titanium as the microalloying additions. The strength, oxidation resistance, and metal dusting resistance improve its use for ethylene pyrolysis coils.
