Haynes® HR-160 Plates (UNS N12160, ASTM B435) are a solid-solution-strengthened nickel-cobalt-chromium-silicon alloy engineered for resistance to a broad range of high-temperature corrosion attack, particularly sulfidation and chlorination in mixed-gas waste-to-energy environments where conventional heat-resistant grades attack quickly.
Table of Contents
HR-160's high silicon content builds a protective oxide that holds up under sulfidizing and chlorine-bearing atmospheres where chromia-forming alloys break down, which is why it is specified for waste-to-energy boiler components and other mixed-gas high-temperature service. It is furnished in the solution-annealed condition and is covered under ASME Section VIII Division 1 for construction up to 815°C (1500°F).
Aurico Alloys LLP supplies Haynes® HR-160 plates to ASTM B435, with full material test certificates to EN 10204 3.1, for waste-to-energy, chemical processing and general high-temperature industrial use.
High-quality Haynes® HR-160 Plates ready for industrial use.
