Abstract VascoMax T-250 is an ultra-high-strength steel that delivers the high strength (250 ksi tensile strength) and toughness of VascoMax 250 (Alloy Digest SA-142, March 1963). Yet VascoMax T-250 contains no cobalt and less molybdenum (both strategic elements) than the standard grade. In addition, the new grade provides higher ductility and toughness. VascoMax T-250 is recommended for aerospace structures, pressure vessels, shafting, bolts, and fasteners. This datasheet provides information on composition, hardness, and tensile properties as well as fracture toughness. It also includes information on high temperature performance and corrosion resistance as well as forming, heat treating, machining, joining, and surface treatment. Filing Code: SA-387.
