S289212-032 - Hobart Fabco 91K2-M .045 Flux-Cored Wire E91T1-K2M

High-Performance Low Alloy Flux-Cored Wire

The Hobart Fabco 91K2-M is a premium gas-shielded flux-cored wire designed to meet the rigorous demands of high-strength structural welding. Classified as AWS E91T1-K2M, this consumable is engineered to deliver a minimum tensile strength of 90,000 psi while maintaining excellent ductility and impact toughness, particularly at lower temperatures. This makes it a preferred choice for industries requiring superior weld integrity, such as offshore fabrication, shipbuilding, and heavy equipment manufacturing.

Formulated for use with mixed shielding gas (typically 75% Argon and 25% CO2), the Fabco 91K2-M offers a stable, smooth arc with a fast-freezing slag system. This characteristic facilitates all-position welding, including vertical-up and overhead, without sacrificing bead contour or quality. The wire's chemistry is balanced to provide consistent mechanical properties in both the as-welded and stress-relieved conditions, ensuring reliability across various project specifications.

The 0.045-inch diameter provides a versatile operating range, suitable for single and multi-pass applications on medium to heavy plate thicknesses. Its low hydrogen weld deposit helps mitigate the risk of cracking in high-strength low-alloy (HSLA) steels. Packaged in a convenient 10 lb spool, this product is suitable for both portable wire feeders and shop environments where smaller batch work or mobility is required.

Technical Specifications

The Fabco 91K2-M excels in applications where standard E71T-1 wires may not meet tensile or impact requirements. It is specifically designed to provide high notch toughness, often required for critical seismic or low-temperature service environments. Users can expect low spatter levels and easy slag removal, contributing to improved productivity and reduced post-weld cleaning time.
