Corrosion Resistance
Hastelloy C-276 provides comprehensive corrosion resistance across multiple challenging environments:
  • Oxidizing and reducing media performance
  • Excellent resistance to pitting, crevice corrosion, and stress corrosion cracking
  • Effective resistance to sulfuric, hydrochloric, phosphoric, and organic acids
  • Capability to resist wet chlorine, hypochlorites, and chlorine dioxide solutions
  • Significant corrosion resistance to high-concentration chloride salt solutions
Manufacturing & Heat Treatment
Precise thermomechanical processing ensures optimal microstructure and properties:
Manufacturing Process
Production typically involves vacuum induction melting (VIM) followed by vacuum arc remelting (VAR) for high purity. Seamless pipes undergo hot extrusion followed by cold rolling or drawing with intermediate solution annealing.
Heat Treatment
Solution annealing at 1120-1170°C (2048-2138°F) with rapid quenching dissolves secondary phases and restores optimum corrosion resistance. Stress relief annealing at 870-980°C (1600-1796°F) minimizes residual stresses.
Product Forms
Available in various configurations to suit application requirements:
  • Round Bars: Various diameters for shafting, fasteners, and valve components
  • Plates: Thicknesses ≥6.0mm for pressure vessels and structural applications
  • Seamless Pipes: Manufactured to ASTM B622/ASME SB622 standards
  • Strips and Sheets: Thin gauges for gaskets, liners, and specialized components
  • Other Forms: Wires, fittings, flanges, and custom forgings
Industry Applications
Hastelloy C-276 serves critical roles across multiple demanding industries:
  • Chemical Processing: Reactors, heat exchangers, and piping systems
  • Pollution Control: FGD system components including absorber towers
  • Pulp and Paper Industry: Digester and bleaching equipment
  • Pharmaceutical Industry: Critical reaction vessels and piping
  • Waste Treatment: Incineration systems and wastewater treatment
  • Oil and Gas: Offshore platform equipment and sour gas handling
  • Nuclear Fuel Processing: Equipment for reprocessing spent nuclear fuel
Welding & Fabrication
Hastelloy C-276 exhibits good weldability using common techniques. For optimal results:
  • Use matching filler metals such as ERNiCrMo-4
  • Maintain clean, contamination-free work environment
  • Avoid sulfur-containing markers or tools
  • Control interpass temperatures and heat input
  • Post-weld heat treatment generally not required
Standards & Specifications
Manufactured to various international standards:
  • Plates, Sheets, and Strips: ASTM B575/ASME SB575
  • Seamless Pipes and Tubes: ASTM B622/ASME SB622
  • Welded Pipes: ASTM B619/ASME SB619
  • Fittings and Flanges: ASTM B366/ASME SB366
  • Bars and Forgings: ASTM B564/ASME SB564
