1. What is UNS R30188?

UNS R30188, also known as Haynes 188 or Udimet 188, is a cobalt-based superalloy engineered for superior high-temperature strength, oxidation resistance, and fabricability. With high cobalt (balance), nickel (20.0-24.0%), chromium (20.0-24.0%), and tungsten (13.0-16.0%), UNS R30188 material offers excellent resistance to oxidation, sulfate deposit hot corrosion, and gaseous sulfidation up to 2000°F (1095°C). Its lanthanum addition (0.02-0.12%) enhances the protective oxide scale, ensuring durability in harsh environments. UNS R30188 alloy steel plate is ideal for aerospace, gas turbines, and industrial furnaces, offering better high-temperature ductility than nickel-based alloys like UNS N06002.

Gangsteel’s UNS R30188 is tailored for demanding applications, providing a robust alternative to nickel alloy steel gradessuch as UNS N07214and UNS R30556.
