HARDBANDING

DURA-X

DURABAND® NC microstructure consists of a hard, but tough tool steel matrix with a high volume of tightly packed microconstituents. This combination ensures excellent wear resistance in open hole drilling as well as being CASING FRIENDLY. Typical hardness values of 57-60Rc can be expected when applied to new tools or properly rebuilt joints. Deposits are smooth and free of any slag. DURABAND® NC can be applied over itself and over TUFFBAND® NC without removal, but only if the surface has been properly cleaned and inspected. DURABAND® NC can be applied over some competitive products without removal.

Postalloy® Tuffband® NC is a high hardness hardband that may be used by itself for casing friendly hardband applications or used as a weld matrix with Tungsten Carbide (WC) when casing protection is not a factor. Ideal for Sour Gas Service Environments.

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.

WeldCor Gouge Wire is an arc cut wire designed to remove hardfacing or hardbanding deposits without air assist.
