The Hobart Fabco 991K2 is a premium gas-shielded flux-cored wire designed for welding high-strength low-alloy steels. Engineered to meet the rigorous demands of heavy industrial fabrication, this wire delivers a nominal tensile strength of 90,000 psi, making it suitable for critical structural components. It is formulated to provide excellent impact toughness at low temperatures, a crucial requirement for industries such as offshore drilling, shipbuilding, and heavy equipment manufacturing where materials are subjected to extreme environmental stress.
This .045-inch diameter wire is packaged on a 33-pound spool, compatible with standard industrial wire feeders. The Fabco 991K2 is classified under AWS A5.29 as E91T1-K2C and E91T1-K2M, offering versatility in shielding gas selection. It performs exceptionally well with both 100% CO2 and 75% Argon/25% CO2 mixtures. The wire features a fast-freezing slag system that supports all-position welding, allowing operators to deposit high-quality welds in flat, horizontal, vertical-up, and overhead positions without sacrificing bead contour or integrity.
For industrial supply managers and fabrication supervisors, the Fabco 991K2 represents reliability. Its low hydrogen deposit (H8) significantly reduces the risk of hydrogen-induced cracking, ensuring code compliance and structural safety. Whether used for crane manufacturing, earthmoving equipment, or structural steel projects requiring higher yield strengths than standard mild steel wires can provide, the Fabco 991K2 delivers consistent mechanical properties and operator appeal.
