Haynes® 556™ alloy, hot rolled, solution annealed plate, 6.4-12.7 mm (1/2 in.) thick, tested at 650°C (1200°F)
Subcategory: Superalloy; Iron Base
Key Words: UNS R30556, AMS 5874, AMS 5877, AMS 5831
Material Notes:
Iron content as balance. Effective resistance to sulfidizing, carburizing, and chlorine-bearing environments at high temperature; good oxidation resistance, fabricability, and excellent high-temperature strength; resists corrosion by molten chloride salts and is resistant to corrosion from molten zinc. Excellent forming and welding characteristics. Applications include tubing and structural members in municipal and industrial waste incinerators, rotary calciners and kilns for minerals processing, and non-rotating components in land-based gas turbines burning low-grade fuels; carbon regenerators, and in processes involving high-sulfur petroleum feedstocks; widely used for hot-dip galvanizing fixtures, spinners, and baskets, high speed furnace fans, air preheaters of diesel engines, the inner covers of coil annealing furnaces, and various high temperature applications in the aerospace industry.
