Inconel 690 N06690 Nickel-Based Alloy Steel Round Bar Hot Rolled Corrosion Resistant with 3mm-650mm Diameter

Inconel 690 N06690 Nickel-Based Nickel alloy steel round bar

 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.

Inconel 690 (N06690) Nickel-Based Alloy Overview:
Nickel-based superalloy INCONEL 690 has excellent corrosion resistance and thermal stability. Excellent resistance to fluoride and hot nitric acid; excellent resistance to acid solution corrosion and stress corrosion in chloride and polythiol acid medium; good crevice corrosion in alkaline medium and oxidation resistance in high temperature atmosphere And chloride corrosion and so on.

Inconel 690 (UNS N06690) nickel-based alloy with a chromium content of 27.0-31.0% and a nickel-based alloy with a nickel content of approximately 59%. Inconel 690 (UNS N06690) nickel-based alloy has excellent resistance to intergranular corrosion and intergranular stress. The ability of corrosion cracking is mainly used for the heat transfer tube material of the steam generator of the pressurized water reactor nuclear power plant. The material of the steam generator heat transfer tube of the pressurized water reactor nuclear power plant has undergone a development process, including 304 austenitic stainless steel, 600 alloy, 800 alloy and 690 alloy. Corrosion failure studies in the service of 600 alloys show that intergranular corrosion and intergranular stress corrosion cracking are the main problems. 690 alloy is used as the heat transfer tube material for the steam generator of the pressurized water reactor nuclear power plant. Since the use in the 1990s, no damage has been reported. The effect is very good.
