The Weld Star CrMo5 ER80S-B6 TIG Wire is a robust chromium-molybdenum low-alloy filler designed for TIG (GTAW) welding of high-strength creep-resisting steels, particularly those containing chromium and molybdenum. It produces strong, ductile welds with reliable mechanical properties, making it well-suited to demanding applications such as pressure vessels, steam boilers, petrochemical equipment and high-temperature structural fabrications.
Engineered from quality raw materials for consistent performance, this TIG wire delivers strong fusion with base metals and excellent bead appearance.
Key Features
CrMo5 Low-Alloy Steel Filler: Specifically formulated for TIG welding chromium-molybdenum steels — such as 1 Cr-0.5 Mo and similar grades — where creep resistance and tensile strength are important.
Copper-Coated Finish: Improves TIG wire feed and arc stability, producing clean welds with minimal spatter.
High Mechanical Strength: ER80S-B6 wire produces weld metal with strong tensile and yield properties, suitable for structural and high-temperature service.
Good Weldability: Designed for smooth, stable TIG arcs with excellent bead appearance and good fusion characteristics.
Suitable for High-Temperature Fabrications: Ideal for components that must withstand elevated service temperatures, such as steam and pressure equipment.
Shielding Gas: Optimised for 100 % argon (I1 per EN ISO 14175) to protect the weld pool and enhance weld quality.
Standards Compliance: Conforms to international TIG filler classifications for ER80S-B6, ensuring predictable chemical and mechanical performance.
Workshop-Friendly Packaging: Supplied on 5kg spools with common TIG diameters 2.40mm and 3.20mm; each spool 1000mm in length.
