Product Description

ASTM B622 ASME SB 622 N06022 Hastelloy C22 2.4602 Alloy Characteristic:

Hastelloy C22 Alloy 2.4602 is an alloy composed of nickel, chromium, and molybdenum. It exhibits better corrosion resistance than other alloys such as Hastelloy C276, C4, and 625. Hastelloy C22 demonstrates excellent resistance to pitting, crevice corrosion, and stress corrosion cracking. Hastelloy C22 possesses exceptional resistance to reduction and oxidation in various processing environments, making it suitable for use in complex environments or diverse manufacturing applications due to its versatile properties.

ASTM B622 ASME SB 622 N06022 Hastelloy C22 2.4602 Nickel Alloy possess prominent resistance performance to different chemical environments, including strong oxidizing matter, such as iron chloride, copper chloride, chlorine, heat pollution liquid(organic and inorganic), formic acid, acetic acid, seawater and salting liquid and so on. Hastelloy C22 alloy can resist the grain boundary precipitate form when jointing heat affected zone, this performance made it can applied in many kinds of chemical processing.

ASTM B622 ASME SB 622 N06022 Hastelloy C22 Alloy Metallurgical structure

Hastelloy C22 2.4602 Nickel Alloy is face-centered cubic lattice structure.

ASTM B622 ASME SB 622 N06022 Hastelloy C22 Alloy Specifications

Hastelloy C-22 is covered by ASME Plate, sheet, strip, bar, tubing and pipe are covered by ASME specifications SB-574, SB-575, SB-619, SB-622 and SB-626 and by ASTM specifications B-574, B-575, B-619, B-622 and B-626. The UNS is NO6022.

ASTM B622 ASME SB 622 N06022 Hastelloy C22 Alloy Corrosion resistance

Hastelloy C22 alloy suit for many kinds of chemical process industry which contain the oxidizing medium and reductant. High molybdenum and chromium content make it can resist the chloride corrosion, and tungsten make this corrosion resistance better.Hastelloy C22 is one of a few material that can resist the corrosion of moist chlorine, hypochlorite and chlorine dioxide, this alloy have prominent corrosion resistance to high concentration chlorate( iron chloride and copper chloride).
