Incoloy Coils And Strips

Incoloy refers to a range of superalloys now produced by the Special Metals Corporation (SMC) group of companies and created with a trademark by the Inco company in 1952. Originally Inco protected these alloys by patent.[2] In 2000, the SMC published a 61-page document entitled "High-Performance Alloys for Resistance to Aqueous Corrosion" highlighting Incoloy, as well as Monel and Inconel products, and their use in fluid environments such as sulfuric acid, hydrochloric acid, hydrofluoric acid, phosphoric acid, nitric acid, other acids as well as freshwater environments.

Incoloy products are mostly chromium-based and mostly nickel-based, and designed for corrosion resistance as well as strength at high temperatures.

Incoloy alloys belong to the category of super austenitic stainless steels.One advantage is that Incoloy alloys do not have to be heat treated after welding to restore the corrosion resistance.
