Abstract

UCI-170 (HL) is similar to HK material, but additional chromium provides better resistance to hot gas corrosion, particularly sulfidation. This alloy is used extensively for tube supports, hangers, and tube sheets. Alloy UCI 170 (HL) also possesses high-temperature strength, useful for service where excessive scaling must be minimized. This datasheet provides information on composition, physical properties, 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: SS-685. Producer or source: Ultra-Cast Inc. Originally published June 1997, corrected August 1997.
