Nickel-Base Alloys—Cabot Wrought Products

TABLE 5.18 NICKEL-BASE ALLOYS-CABOT WROUGHT PRODUCTS 

HASTELLOY alloy B-2—An improved wrought version of HASTELLOY alloy B. Alloy B-2 has the same excellent corrosion resistance as alloy B, but with improved resistance to knife-line and heat-affected zone attack This alloy resists the formation of grain-boundary carbide precipitates in the weld heat-affected zone, thus making it suitable for most chemical process applications in the as-welded condition. Alloy B-2 also has excellent resistance to pitting and stress-corrosion cracking it is particularly well suited for equipment handling hydrogen chloride gas. and hydrochloric, sulfuric, acetic, and phosphoric acids. 

HASTELLOY alloy C-27 —An improved wrought version of HASTELLOY alloy C with vastly improved fabricability. It has outstanding resistance to a wide variety of chemical process environments including strong oxidizers, i.e.. ferric and cupric chiorides. hot contaminated mineral acids, solvents, chlorine and chloride-contaminated media (organic aitd inorganic). dry chlorine, formic and acetic acids, acetic 

HASTELLOY alloy G—A columbium-stabilized. nickel-base alloy with excellent resistance to hot sulfuric and phosphoric acids Alloy G will withstand the corrosive affects of both oxidizing and reducing agents and can handle both acid and alkaline solutions. It resists pitting and has exceptional resistance to stress-corrosion cracking 

HASTELLOY alloy X—A heat-resistant, nickel-base alloy ideally suited for chemical plant equipment. It has good high-temperature strength and exceptional resistance to oxidizing atmospheres.
