Product Catalog
Executive 71T-12MJ is an all-position flux-cored wire designed for single or multi-pass applications that demand exceptional weld metal toughness. It maintains excellent impact toughness down to -50°F (-46°C) in the as-welded and typical post weld heat treated (PWHT) condition. Executive 71T-12MJ also boasts a smooth arc with fast freezing slag and low spatter levels, characteristics shared with other executive flux-cored wires. Additionally, unlike many other products in the market, Executive 71T-12MJ supports an “H4” low-hydrogen designation.
Application and Features
Applications include off-shore oil components, shipbuilding, pressure vessels, structural and bridge fabrication and heavy equipment where exceptional charpy impact/low temperature toughness is required. The precisely optimized chemical composition of the weld metal imparts exceptional mechanical properties, making it well-suited for even the most stringent industry specifications.
