2. Operating Conditions & Selection GuidelinesIdeal Media: Superior resistance to both oxidizing acids (nitric, ferric salts) due to chromium content and reducing acids (hydrochloric, sulfuric) due to molybdenum and copper addition. Particularly effective in environments requiring resistance to a broad mix of corrosives Critical Advantage: Optimized chemistry balances resistance to oxidizing and reducing media without the trade-offs found in previous alloys. Excellent resistance to chloride-induced stress corrosion cracking that affects austenitic stainless steels Temperature Range: Solution annealed at appropriate temperatures. Maintains mechanical integrity across typical chemical processing temperature ranges Common Applications: Chemical reactors, heat exchangers, piping systems, pollution control scrubbers, stack liners, pharmaceutical processing equipment, sour gas handling components, and pulp and paper bleach plants
3. Fabrication & Material ComparisonForming Characteristics: Ductile nature allows for easy forming and fabrication into complex shapes using standard equipment. Suitable for both hot and cold working operations Welding Considerations: Excellent weldability using common techniques including GTAW/TIG, GMAW, and SMAW. Maintains corrosion resistance in welded areas without significant property loss when proper procedures are followed Machining: Can be machined using standard techniques appropriate for nickel-based alloys. Work-hardening characteristics require rigid setups and sharp tooling Versus C-276: C-2000 offers improved resistance in oxidizing media due to higher chromium content, while maintaining comparable performance in reducing environments. The copper addition provides enhanced resistance to sulfuric acid Versus C-22: Higher chromium and molybdenum content with copper addition gives C-2000 broader resistance across mixed-acid environments, particularly where sulfuric acid is present Versus 316L Stainless: Dramatically superior resistance to chlorides, reducing acids, and mixed corrosives. Specified where stainless steels experience rapid localized corrosion or SCC Product Forms: Available as plates, sheets, strips, billets, bars, wires, pipes, tubes, covered electrodes, and custom fabrications
