S295750-020 - Hobart SDX EM14K 5/32" SAW Wire 55lb Coil

Hobart SDX EM14K Submerged Arc Welding Wire

The Hobart SDX EM14K is a premium-grade, copper-coated solid carbon steel wire specifically engineered for the Submerged Arc Welding (SAW) process. Manufactured to meet the rigorous AWS A5.17 EM14K classification, this wire is formulated with a precise balance of manganese and silicon, enhanced with titanium. This specific chemical composition is critical for industrial applications requiring superior mechanical properties, particularly in environments where low-temperature impact toughness is a mandatory requirement. The inclusion of titanium acts as a grain refiner, ensuring that the weld metal retains high toughness even when subjected to the high heat inputs typical of submerged arc welding.

Designed for heavy-duty industrial fabrication, the SDX EM14K excels in both single-pass and multiple-pass welding operations. When used in conjunction with neutral or active fluxes, it produces a smooth, consistent weld bead with excellent slag detachability, reducing post-weld cleanup time. The copper coating on the wire not only improves electrical conductivity at the contact tip but also provides resistance against corrosion during storage, ensuring the wire feeds smoothly without jamming or arc instability.

This 5/32-inch (4.0mm) diameter wire is supplied in a 55lb (25kg) coil, making it suitable for continuous, high-volume welding stations found in shipyards, structural steel plants, and heavy equipment manufacturing facilities. Its ability to maintain Charpy V-Notch (CVN) toughness values at lower temperatures makes it an ideal choice for fabricating bridges, storage tanks, and pressure vessels where structural integrity cannot be compromised. By choosing Hobart SDX EM14K, fabricators ensure a high-quality metallurgical bond that meets stringent industry standards.
