Quick Answer: What Is Haynes 188?

Haynes 188 (UNS R30188 / W.Nr. 2.4683) is a cobalt-nickel-chromium-tungsten superalloy that uniquely combines excellent high-temperature strength with outstanding resistance to oxidizing environments and sulfidation up to 1095°C (2000°F). Strengthened primarily by solid-solution elements and stabilized by a rare-earth addition (Lanthanum), it maintains superior ductility and fabricability compared to other high-strength cobalt alloys. Shanghai Hangbo Alloy Group supplies Haynes 188 as precision round bars, seamless tubes, and plates with full EN 10204 3.1 certification.
