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
