ABEX HC-250 comprises a family of heat-treatable, high-chromium iron casting alloys specially developed to offer superior abrasion resistance where other materials have failed. The microstructure of HC-250 consists of an iron and chromium-rich mixture of martensite and austenite containing very hard, discrete, needle-like particles of chromium carbide. This unique combination of constituents gives HC-250 its outstanding abrasion resistance, corrosion resistance, good rupture life and oxidation resistance at high temperature. This datasheet provides information on composition, physical properties, microstructure, hardness, elasticity, tensile properties, and compressive strength as well as creep. It also includes information on high temperature performance, corrosion and wear resistance as well as casting, heat treating, and machining. Filing Code: CI-45.
