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.AISI 8822 is a nickel-chromium-molybdenum carburizing steel of fairly high hardenability. Its high core strength and durable carburized case make it suitable for many heavy-duty applications. It can also be used without carburizing.
