Hastelloy® Alloy Coil (C-276, C-22, B-3, etc.)
Engineered for industries battling extreme chemical corrosion, high-temperature stress, and continuous fabrication demands, Hastelloy® alloy coils deliver unparalleled performance in aggressive environments. With nickel-molybdenum-chromium matrices (e.g., C-276: Ni-57%, Mo-16%, Cr-15.5%), these coils excel in applications where stainless steel and standard alloys fail. Certified to ASTM B619, ASME SB619, and NACE MR0175, they outperform competitors with 15x longer service life in HCl, H₂SO₄, and Cl⁻-rich media, ensuring reliability in chemical processing, oil & gas, and nuclear sectors.

FAQ
Q1: How does Hastelloy C-276 coil compare to Inconel 625 in HCl service?
A: C-276 offers 50% lower corrosion rate in 20% HCl at 50°C, while Inconel 625 excels in higher-temperature oxidation resistance.
Q2: What welding parameters prevent carbide precipitation in C-276?
A: Use ERNiCrMo-4 filler with TIG welding, limit heat input to **≤1.5 kJ/mm**, and post-weld anneal at 1,120°C (2,048°F) for optimal corrosion resistance.
