Description
Ultraband™NM is a hard, 100% crack free Hardband designed for non-mag drill collars and related components. Control of critical elements has resulted in a hardband alloy that meets magnetic permeability specifications and offers substantially improved wear resistance compared to conventional non-mag welding alloys, like 310 stainless – a 400% to 500% improvement. In addition, the abrasion resistance of Ultraband™NM is 400% to 500% better than drill collar base materials.
