MAR-M Alloy 509 is a vacuum melted, cobalt-base alloy having high strength, low creep rates, and resistance to oxidation and thermal shock. It is recommended for aircraft and industrial gas turbine applications. This datasheet provides information on composition, physical properties, hardness, and tensile properties as well as creep. It also includes information on high temperature performance and corrosion resistance as well as casting, heat treating, machining, and joining. Filing Code: Co-54. Producer or source: Martin Metals Division, Martin Marietta Corporation.

MAR-M Alloy 918 is a cobalt-base alloy for service in applications where high strength and oxidation resistance are required. This datasheet provides information on composition, physical properties, and tensile properties as well as creep. It also includes information on corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: Co-63. Producer or source: Martin Metals Division, Martin Marietta Corporation.

1049 is a wrought medium-carbon (carbon = 0.46-0.53%) non-alloy steel that is used in the normalized, cold worked, or quenched and tempered condition. 1049 may also be flame or induction hardened, nitrided, or nitrocarburized. This steel is widely used for moderately and highly stressed parts that require higher strength levels than can be achieved by the lower carbon grades, and where the expense of an alloy steel is not justified. Owing to its low hardenability, its use in the quench hardened and tempered condition is not recommended for large sizes, as the improvement in mechanical properties over the normalized condition is insufficient to justify the additional cost of heat treatment. This datasheet provides information on composition, physical properties, hardness, and tensile properties. It also includes information on forming and heat treating. Filing Code: CS-257.
