Formula 5551 flux cored wire withstands high-heat conditions for extreme welding applications by maintaining superior hardness retention in temperatures as high as 1200°F (650°C). Testing proves that the hardness capabilities of formula 5551 continue to improve as the temperature increases. It is highly resistant to heat checking in environments where coolants are used, extremely resistant to abrasion and tolerant of compressive loads. With a 30% higher deposition rating than typical flux cored wire, formula 5551 also offers high weldability for general welding applications. In addition, extrusion dies benefit from its higher wear capabilities.
