Material Overview
Hastelloy C-276 is a nickel-chromium-molybdenum alloy renowned for exceptional corrosion resistance in severe chemical environments. This versatile material maintains excellent performance in both oxidizing and reducing conditions, making it ideal for critical applications in chemical processing, pollution control, and demanding industrial sectors.
Chemical Composition
The outstanding corrosion resistance of Hastelloy C-276 stems from its carefully balanced chemical composition, featuring strategic additions of chromium, molybdenum, and tungsten for robust defense against corrosive media.

Physical & Mechanical Properties
Hastelloy C-276 exhibits favorable physical and mechanical properties suitable for both corrosive and high-temperature applications.
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
