Clifton Steel's Tensaweld Ultra-300 is a tubular wire for open arc hardfacing components.

The Ultra-300 weld wire has been designed for components that undergo wear in extreme abrasion, high-stress grinding applications. The deposit contains multiple carbides in a tough iron matrix. Clifton Steel recommends using this wire for single layer application. 

Clifton Steel strives to provide our customers with a confident experience while deciding what wire to purchase. That's why we've taken the guesswork out of the buying experience. By developing these wires to compliment our products, we guarantee compatibility when partnered with our material.
