ER80S-B8 MIG & TIG Welding Wire

At Metals And Welding Specialities, we supply precision-engineered ER80S-B8 MIG & TIG Welding Wire designed for superior performance in high-temperature and high-pressure environments. This solid wire, classified under UNS K90941 and conforming to ASTM A182 Grade F9, is a trusted choice for fabricators and industries that demand exceptional weld integrity, oxidation resistance, and consistent mechanical strength. Manufactured with an optimized 9% chromium and 1% molybdenum composition, ER80S-B8 provides outstanding resistance to scaling and corrosion, making it ideal for service applications involving steam, pressure vessels, and petrochemical systems.

The ER80S-B8 welding wire is designed for joining and overlay welding of Cr-Mo steels such as ASTM A182 F9, A336 F9, and A217 C9 castings. Its chemical balance delivers excellent creep strength and toughness, ensuring durability even under prolonged thermal exposure. Whether used for MIG (GMAW) or TIG (GTAW) processes, the wire exhibits stable arc characteristics, smooth feedability, and minimal spatter, leading to cleaner welds and reduced post-weld finishing. These performance attributes make it a reliable solution for power generation, refineries, and boiler manufacturing applications.

Each batch of ER80S-B8 from Metals And Welding Specialities is produced to meet rigorous metallurgical standards. Its low carbon content enhances resistance to carbide precipitation, helping maintain weld metal toughness after post-weld heat treatment (PWHT). The filler metal also ensures strong metallurgical compatibility with base materials containing similar Cr-Mo alloys. Customers can rely on this product for consistent weld bead appearance, crack resistance, and excellent mechanical properties even in cyclic temperature environments.

The ER80S-B8 filler metal performs exceptionally well with shielding gases such as argon or argon/CO₂ mixtures for MIG welding, while pure argon is preferred for TIG applications. It is widely used in fabricating heat exchangers, superheater tubes, and steam pipes, where reliability and metallurgical stability are critical. As an industry leader, Metals And Welding Specialities ensures that every spool or cut length of ER80S-B8 wire is manufactured, tested, and packed under strict quality control to deliver optimal welding outcomes and long service life in demanding applications.

If you’re seeking a robust, dependable, and technically advanced ER80S-B8 welding wire, trust Metals And Welding Specialities to provide consistent quality that meets both international and project-specific specifications. We understand the precision and durability required in modern industrial welding, and our ER80S-B8 MIG & TIG wire stands as a testament to our commitment to metallurgical excellence.
