Product Catalog
Executive 90S-B3 is designed for welding of 2¼ Cr - 1 Mo steels using MIG or TIG welding processes where high temperature service and creep resistance is important. The alloy content of the wire produces weld metal that matches the base material and maintains mechanical properties after post-weld heat treatment. The Executive 90S-B3 also offers tightly controlled low melting residual elements to meet X factor of less than 15 in order to resist temper embrittlement. Executive 90S-B3 filler metal is produced using high quality raw materials and tightly controlled chemistry to provide top quality, exceptionally clean wires that deliver smooth feedability and the results fabricators demand.
Application and Features
Executive 90S-B3 is used to weld 2¼ Cr - 1 Mo steels for elevated service temperatures and creep resistance such as pressure vessels and pressure piping. Typical material grades include ASTM A387-Gr 22, A335-Gr 22 and F182-Gr 22.
This wire is also suitable for laser welding and WAAM applications (Wire Arc Additive Manufacturing, aka Metal 3D printing).
