Excellent Corrosion Resistance

Abstract HASTELLOY alloy B-2 has outstanding corrosion resistance in the as-welded condition. It is an improved wrought version of HASTELLOY alloy B with the same excellent corrosion resistance as alloy B, but with improved resistance to knife line and heat-affected zone attack. Alloy B-2 resists the formation of grain-boundry carbide precipitates in the weld heat-affected zone, thus making it suitable for most chemical process applications in the as-welded condition. This alloy also has excellent resistance to pitting and stress-corrosion cracking. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties. It also includes information on high temperature performance and corrosion resistance as well as forming, heat treating, machining, joining, and surface treatment. Filing Code: Ni-249. Producer or source: Stellite Division, Cabot Corporation.

Hot Rolled

Abstract ATI 425 was originally developed for hot-rolled armor plate to provide ballistic protection comparable to Ti-6Al-4V and has been evaluated against a variety of projectile threats for use as armor. While processing the alloy for armor plate applications, it was observed that the material exhibited very good hot workability, permitting a more lenient window of processing parameters than necessary for Ti-6Al-4V. Versatility then expanded, and applications now exist in the chemical process industry (CPI) and in the aerospace industry. This datasheet provides information on composition, physical properties, and tensile properties as well as fracture toughness and fatigue. It also includes information on corrosion resistance. Filing Code: TI-133. Producer or source: ATI Wah Chang, Allegheny Technologies. Originally published March 2004, revised July 2004.

Abstract Tantalum finds its largest use in the electronics industry, where it is used in filaments, filament supports, and capacitors. Metallurgical grade tantalum is used extensively in chemical process equipment. Tantalum resists corrosion by body fluids and is used in prosthetic devices. Its high melting point gives it utility in vacuum furnace components. It is also used as an alloying element in superalloys. This datasheet provides information on composition, physical properties, and tensile properties. It also includes information on corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: Ta-11. Producer or source: Cabot Corporation.
