Downhand rutile flux cored wire for welding armour plate.
Rutile flux cored wire made with an austenitic stainless steel sheath and rutile flux system designed primarily for downhand and horizontal welding, giving a mitred fillet profile. The 1.2mm diameter wire is also suitable for all positional welding. Metal recovery is approximately 90% with respect to wire.
Applications
These consumables are well-established and approved for armour welding. They deposit a modified austenitic stainless weld metal with moderately high ferrite content, giving strong, tough and crack-resistant welds in many other hardenable steels, often without the need for preheat. Applications include tanks, other military and security vehicles, and general engineering components. They are also useful for welding many wear and abrasion-resisting steels, to avoid the need for 'hydrogen control' procedures, particularly for heavier sections and the harder types. In addition, the high work-hardening rate gives these welds good resistance to impact wear and scuffing. This feature can also be exploited for overlays combined with corrosion and wet abrasion resistance. Although the resistance to gouging abrasion of 13% Mn Hadfield steel is unique and arises from its extreme work-hardenability, these consumables have a long and successful history for the build-up and reclamation of this steel. It is an economically ductile buffer layer before hardfacing with high alloy weld metals such as chromium carbide types.
