Haynes® Plates | Extreme High-Temperature Alloy Solutions
Table of Contents:
When a GE gas turbine suffered blade failures costing $12M during peak demand after only 8,000 hours at 1100°C due to oxidation/creep of conventional nickel alloys, engineers specified Haynes® Plates Haynes 230 plates extended life to 40,000+ hours with 4x better rupture strength and superior sulfidation resistance. Aerospace OEMs, power plant procurement directors, petrochemical fabricators, and nuclear engineers now demand these cobalt/nickel-based superalloys (Haynes 25/188/230/282) where Inconel, Hastelloy, or stainless alternatives fail catastrophically under extreme heat, stress, and corrosive combustion gases.
Haynes 25 (UNS R30605) delivers 125 ksi tensile and 1000°F service with wear resistance unmatched by nickel alloys, while Haynes 230 (UNS N06230) offers premier oxidation resistance to 2100°F 100x longer life than 625 in nitriding service. Haynes 188 (UNS R30188) provides cobalt-based sulfidation resistance critical for land-based turbines burning dirty fuels, and Haynes 282 (UNS N07208) surpasses Waspaloy in 1200-1700°F creep strength for next-gen turbine discs.
Aurico Alloys LLP supplies affordable, authentic Haynes® Plates as trusted supplier, manufacturer, and stockist for chemical, oil & gas, marine, pharma, power industries, and hardware stores with NABL-approved Mill Test Certificates and AMS/ASTM compliance.
