When a major refinery’s distillation columns experienced rapid corrosion even with high-alloy steel, switching to Hastelloy Sheets delivered a breakthrough. These superalloy materials enabled a 3x increase in service life and halved maintenance frequency for process, marine, pharma, oil & gas, and power generation plants. Today, procurement and engineering teams worldwide rely on Hastelloy for proven, certified reliability in critical environments where ordinary alloy sheets fail.
Table of Contents:
Hastelloy sheets (ASTM B575: UNS N06022, N10276; DIN 2.4602, 2.4819) are solid-solution, high-purity nickel-chromium-molybdenum superalloys. Grades like C22 and C276 offer exceptional resistance to oxidizing and reducing acids, chloride pitting, and stress corrosion cracking performing far beyond SS316, Alloy 20, or simple duplex grades. With ultra-low carbon, silicon, and iron, Hastelloy sheets retain their toughness and ductility even after years in aggressive chemical and marine settings.
Aurico Alloys LLP supplies Hastelloy Sheets across all critical ASTM B575 grades, in stock from 0.2 mm to 4.75 mm thickness, widths up to 2500 mm, and customizable formats bright-annealed, polished, hot or cold-rolled. Every sheet comes with EN 10204/3.1 mill test certification, PMI, and REACH/RoHS documentation. As a trusted manufacturer, supplier, and stockist, we provide the global process industry with the best-in-class, traceable nickel alloy sheet solutions enabling robust, safe designs.
Whether for acid condensers, heat exchanger plates, FGD scrubbers, bio-reactor vessels, or marine desalination infrastructure, Hastelloy’s stable composition and excellent weldability reduce unplanned outages and support safety compliance. Its high tensile and yield strengths, combined with 45% elongation, enable reliability under cyclic and sustained loads outperforming stainless or Alloy 400 alternatives .
High-quality Hastelloy sheets ready for industrial use.
