CARPENTER NIMARK 300 is a vacuum-melted, low-carbon nickel-cobalt-molybdenum maraging steel that develops yield strengths in excess of 270,000 psi (1862 MPa) by simple low-temperature aging at 900 F (482 C) following a solution anneal. It is readily weldable and exhibits good ductility at high strength levels and excellent notch ductility. Its many uses include aircraft structural assemblies, pressure vessels, shafting, bolts and fasteners, and rocket motor cases. 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 low and high temperature performance as well as forming, heat treating, machining, and joining. Filing Code: SA-423. Producer or source: Carpenter.

G.110 is an 18% nickel alloy steel, possessing an excellent combination of toughness and ductility at yield strength levels of 250,000 psi. The strength developed is independent of mass effect and rate of cooling, and is achieved by a simple aging treatment. The alloy is recommended for applications such as rocket motor cases and accessories, bolts and fasteners and aircraft structural components- particularly landing gear. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties as well as fracture toughness. It also includes information on forming, heat treating, joining, and surface treatment. Filing Code: SA-225. Producer or source: Jessop-Saville Ltd, Brightside Works.
