This group of materials, Nickel Alloys, Cobalt Alloys, Special Alloys and Super Alloys is primarily used in extremely high temperature and/or corrosive environments, such as jet engines, power generation applications, chemical plants, and oil rigs. Typically, nickel alloys or cobalt alloys are used in environments where the use temperatures are in access of 1000 degrees F.
Due to their chemical compositions, materials tend to be quite expensive, with long lead times from the mills. Steel service centers tend not carry large inventories of expensive materials, sometimes making it difficult to obtain, particularly in immediate repair situations.
Some of the more well-known trademarked alloys include Inconel®, Hastelloy®, Monel®, Nitronic®, CBS600, Haynes 188®, L605®, and Rene 41®. These also tend to be price volatile with the longest mill lead times, as much as 52 weeks or more.
