S234219-029 - Hobart FabTuf 960 Hardfacing Wire 1/16" 33lb Spool

Technical Overview of Hobart FabTuf 960

The Hobart FabTuf 960 is a premium gas-shielded, metal-cored hardfacing wire designed to deposit a martensitic steel alloy. Engineered for industrial applications requiring a balance of high abrasion resistance and moderate impact tolerance, this wire is an essential consumable for maintenance and repair operations (MRO) in the mining, construction, and dredging sectors. The wire has a diameter of 1/16 inch and is supplied on a 33-pound spool, making it compatible with standard industrial wire feeders capable of running larger diameter cored wires.

Technically, the FabTuf 960 achieves a deposit hardness in the range of 55-60 Rockwell C (HRC). This hardness level is attained through a specific alloy chemistry that responds to the cooling rates typical of arc welding. The wire is designed for use with 100% CO2 shielding gas, which promotes deep penetration and a stable arc transfer. The metal-cored construction allows for higher current densities and deposition rates compared to solid wires, increasing productivity during extensive buildup or overlay operations. It is suitable for both single and multiple pass applications, allowing operators to build up worn surfaces to original dimensions before applying the final hardfacing layer, or to use this product as the primary wear-resistant surface.

The deposit characteristics include a smooth bead profile with minimal slag, reducing post-weld cleanup time. While primarily focused on abrasion resistance due to its high hardness, the formulation retains sufficient toughness to withstand moderate impact loads without cracking or spalling, provided proper preheat and interpass temperature controls are observed. This makes it a versatile choice for components subjected to sliding wear combined with occasional shock loading.

Industrial Specifications

This product is categorized under hardfacing consumables and is specifically tailored for carbon steel and low-alloy steel substrates. The use of CO2 shielding gas not only lowers the cost of operation but also assists in achieving the desired metallurgical properties of the weld deposit. Operators should ensure their equipment is rated for the duty cycle required to run 1/16" wire continuously, as hardfacing often involves long arc-on times.
