FANSTEEL 80 METAL is a columbium-base alloy containing nominally 1% zirconium. It is produced by electron-beam melting which gives it exceptionally high interstitial purity. It is several times stronger than pure columbium at elevated temperature; and this is without sacrificing the ease of fabrication associated with columbium. Fansteel 80 Metal can be fabricated easily at room temperature and high-quality ductile welds are possible. Its applications include nuclear, liquid metal loops and structures for high-temperature environments. This datasheet provides information on composition, physical properties, elasticity, and tensile properties as well as fracture toughness. It also includes information on corrosion resistance as well as forming, heat treating, machining, joining, and surface treatment. Filing Code: Cb-10. Producer or source: Fansteel Metallurgical Corporation. Originally published August 1966, revised November 1981.

FANSTEEL 85 METAL is a columbium-base alloy characterized by good fabricability at room temperature, good weldability and a good combination of creep strength and oxidation resistance at elevated temperatures. Its applications include missile and rocket components and many other high-temperature parts. This datasheet provides information on composition, physical properties, microstructure, hardness, elasticity, tensile properties, and bend strength as well as creep. It also includes information on low and high temperature performance as well as forming, heat treating, machining, joining, and surface treatment. Filing Code: Cb-7. Producer or source: Fansteel Metallurgical Corporation. Originally published December 1963, revised June 1981.

FANSTEEL 291 METAL is a columbium-base alloy that can be readily fabricated, machined and welded. It is used in the high-temperature range 2800-3500 F where excellent strength-to-weight ratio can be used to advantage. It is also used in the lower temperature range 2000-2700 F because of its availability and fabricability which may be of more importance than high strength alone. This datasheet provides information on composition, physical properties, hardness, and tensile properties as well as fracture toughness and creep. It also includes information on high temperature performance and corrosion resistance as well as heat treating, machining, and joining. Filing Code: Cb-20. Producer or source: Fansteel Metallurgical Corporation.

Fansteel 82 is a columbium base alloy having superior high temperature strength while retaining the good fabricability of pure columbium. Fansteel 82 exhibits superior resistance to oxidation at temperatures above 1800 F; however, a protective coating will be necessary except for only very short time applications. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties as well as creep. It also includes information on high temperature performance as well as forming, heat treating, machining, joining, and surface treatment. Filing Code: Cb-3. Producer or source: Fansteel Metallurgical Corporation.

TANTALUM is a high-density, ductile metal with excellent resistance to corrosion by most acids and good high-temperature properties. This datasheet provides information on composition, physical properties, elasticity, tensile properties, and bend strength. It also includes information on high temperature performance and corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: Ta-2. Producer or source: Kawecki Berylco Industries Inc.. See also Alloy Digest Ta-10, June 1988.

TRIBOCOR 532N is a refractory alloy (columbium base) produced by conventional melting, casting and working techniques. In its final form the product made of this alloy is nitrided to develop superior corrosion and wear-resistant characteristics. This datasheet provides information on composition, physical properties, microstructure, elasticity, tensile properties, and compressive strength. It also includes information on high temperature performance, corrosion and wear resistance as well as forming. Filing Code: Cb-22. Producer or source: Fansteel Metallurgical Corporation.

Columbium SCB-291 is a columbium-base alloy having excellent high temperature properties and good fabricability. It is recommended for nuclear reactors, space vehicles, jet and missile components. This datasheet provides information on composition, physical properties, hardness, and tensile properties as well as creep. It also includes information on high temperature performance as well as forming, heat treating, machining, and joining. Filing Code: Cb-14.
