HARDBAND NB-O
DIN 8555: MF 10-GF-55-GPS
EN 14700 T Fe6
• Flux-cored wire for gas or gasless self-shielded welding
• The weld deposit contains finely dispersed niobium carbides in a martensitic matrix.
• Gives highly abrasion-resistant crack-free deposit, which may be machined despite its high hardness.
• Suitable for multi-layer and re-weld straight on previous weld deposit.
• WA HARDBAND NB-O is designed for hardfacing / hardbanding of tool joint subjected to extreme wear conditions. The deposit contains no cracks or pores, yet possesses the exceptional hardness and abrasion resistance.
• WA HARDBAND NB-O was specifically designed and manufactured to extend the life of tooling for downhole drilling applications. Ex. Drill Pipe, Heavy Weight Drill Pipe, Drill Collars, & Tool Joints
