Nimonic93 GH93 alloy round bar pipe plate wire coil Incoloy 800 800H 800HT 901 925 926

Incoloy is a nickel ferrochrome alloy designed for oxidation and carbonation at elevated temperatures.Incoloy alloy has many kinds: common such as Incoloy800, Incoloy800H, Incoloy800HT, Incoloy825, Incoloy840, Incoloy901, Incoloy925, Incoloy20, Incoloy330, Incoloy 25-6mo, etc.The alloy contains a small amount of the metallic elements molybdenum and copper.In reductive acid and oxidizing acid, it has good corrosion resistance, as well as good resistance to stress corrosion cracking, pitting and crevice corrosion.It has excellent corrosion resistance to sulfuric acid and phosphoric acid.The alloy has good cold and hot working properties and is easy to be formed and welded.The main products of this alloy are rods, tubes, plates, strips, wires and forgings, etc. It is mainly used in the chemical, petrochemical, nuclear and rare metal refining industries.

Nickel-based superalloys refer to high-temperature alloys with high strength and good resistance to oxidation and gas corrosion in the range of 650-1000 ° C with nickel as the matrix (generally greater than 50%). Nickel-based superalloys (hereinafter referred to as nickel-based alloys) were developed in the late 1930s. In 1941, the United Kingdom first produced the Ni-based alloy Nimonic 75 (Ni-20Cr-0.4Ti); in order to increase the creep strength and added aluminum, Nimonic 80 (Ni-20Cr-2.5Ti-1.3Al) was developed. In the mid-1940s, the Soviet Union in the late 1940s, China also developed nickel-based alloys in the mid-1950s.
