General Proprieties
Alloy 625 (UNS N06625) is a nickel-based superalloy that possesses high strength properties and resistance to elevated temperatures. It also demonstrates remarkable protection against corrosion and oxidation.
Alloy 625 (grade 1) is used in the oil and gas industry, the chemical process industry, marine engineering and environmental engineering.
Typical applications include: Equipment for the production of super phosphoric acid, Plants for the treatment of radioactive waste, Production pipe systems and linings of risers in oil production, Offshore industry and seawater exposed equipment, Sea water piping in shipbuilding, Stress corrosion cracking resistant compensators, Furnace linings.
Alloy 625 (grade 2) is used for high temperature applications up to 1,000 °C, acc. to ASME Code for Pressure Vessels.
Typical applications include: Flaring systems in refineries and offshore platforms, Recuperators and compensators for hot exhaust gases.
Alloy 625 is used as a matching filler metal for corrosion-resistant coatings of less resistant steels (overlay welding).
Typical applications include: Components in the oil and gas extraction, Superheater tubes in waste incineration plants. This alloy is also know as Inconel® 625, Chronin® 625, Altemp® 625, Nickelvac® 625 and Nicrofer ® 6020 hMo. Alloy 625 is available at CHUN & VOLLERIN in these formats: Bars, Plates, Stripes.
