Heat Treatment of Hastelloy C-2000 Round Bars

Hastelloy C-2000 is generally supplied in annealed condition, which ensures optimal corrosion resistance and mechanical properties.

Annealing Process

• Heat to 1175 – 1220°C
• Rapid water or air quench to maintain mechanical properties
• Relieves residual stresses and restores ductility

Annealing ensures high corrosion resistance, dimensional stability, and machinability.

Machinability of Hastelloy C-2000 Round Bars

Hastelloy C-2000 is moderately machinable, but requires specialized tooling due to its high work-hardening tendency:

• Use sharp carbide or polycrystalline diamond (PCD) tools
• Employ slow cutting speeds and high coolant flow
• Avoid excessive heat generation to prevent surface work hardening
• Suitable for turning, milling, drilling, and precision machining

Proper machining ensures smooth surfaces and accurate dimensions for chemical and industrial applications.

Corrosion Resistance of Hastelloy C-2000 Round Bars

• Exceptional resistance to oxidizing and reducing acids
• Superior resistance to chloride-induced stress corrosion cracking
• Stable in nitric acid, hydrochloric acid, sulfuric acid, and phosphoric acid
• Performs well in marine and offshore environments

Hastelloy C-2000 round bars are ideal for chemical processing, seawater handling, and industrial systems exposed to corrosive media.

Weldability of Hastelloy C-2000 Round Bars

Hastelloy C-2000 can be welded using standard arc welding processes:

• TIG (GTAW), MIG (GMAW), and SMAW are suitable
• No preheating generally required
• Filler material: Hastelloy C-2000 compatible weld rods or C-22 filler for optimum corrosion resistance
• Post-weld annealing recommended for maximum performance

Welding ensures strong joints with minimal reduction in corrosion resistance.
