Hastelloy C-276 FAQ

What makes Hastelloy C-276 different from other nickel alloys?

Hastelloy C-276 contains higher molybdenum (15-17%) and chromium (14.5-16.5%) content compared to other nickel alloys, providing superior resistance to pitting, crevice corrosion and stress-corrosion cracking in chloride environments and mixed acids.

Can Hastelloy C-276 be welded?

Yes, Hastelloy C-276 has excellent weldability and can be welded using TIG, MIG, SMAW and other processes. The material does not require post-weld heat treatment and maintains its corrosion resistance in the as-welded condition.

What are the machining challenges with C-276?

Hastelloy C-276 work hardens rapidly and has low thermal conductivity, requiring sharp tools, slow cutting speeds, high feed rates and proper coolant. We use specialized carbide tooling and optimized parameters to achieve quality results.

Do you provide material certificates for C-276?

Yes, we provide complete material traceability including mill test reports (MTR), chemical composition analysis per ASTM B575, and mechanical property certifications. All material is sourced from certified suppliers with full documentation.

What tolerances can you achieve with C-276 machining?

Our precision CNC machining can achieve tolerances as tight as ±0.01mm on critical dimensions for Hastelloy C-276. Standard tolerances are ±0.05mm with surface finishes down to Ra 1.6μm achievable with proper tooling and parameters.

What is the typical lead time for C-276 parts?

Lead times vary based on part complexity and material availability. Typical production ranges from 3-5 weeks for standard parts. We provide detailed scheduling during quotation and can accommodate expedited requirements when needed.
