Executive 90S-B9 is designed to weld P91 and P92 type 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 treat.  The Executive 90S-B9 offers tightly controlled low melting residual elements to meet X factor of less than 15 in order to resist temper embrittlement. Executive 90S-B9 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.
