Abstract

NAS NW22 is a Ni-Cr-Mo alloy with excellent corrosion resistance in both oxidizing and reducing atmospheres. In this alloy, carbide precipitation in the heat affected zone (HAZ) is suppressed, and corrosion resistance is improved by reducing the contents of C and Si. Based on these features, NAS NW22 is widely used in materials under severe environments such as chemical plants. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties. It also includes information on corrosion resistance as well as forming, heat treating, and joining. Filing Code: Ni-696. Producer or source: Nippon Yakin Kogyo Company Ltd.
