MATRIX I is an ultra high-strength alloy steel capable of reaching tensile strength values up to 360,000 psi and maintaining high strength levels at operating temperatures to 1000 deg F. It combines extremely high strength with ductility, toughness, fatigue and heat resistance. The alloy was formerly designated VASCOJET M-A(CVM); see Alloy Digest SA-150, July 1963. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties as well as fracture toughness and fatigue. 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-449.
