Dây hànWear-resistant wire is a kind of wire which can resist more than two kinds of compound wear.

Classification method

1) Iron-based hardfacing wire and non-iron-based hardfacing wire can be divided into two categories according to their chemical composition and microstructure. Such as iron-based hardfacing wire can be divided into high chromium alloy hardfacing wire, Tungsten Carbide hardfacing wire, non-iron-based hardfacing wire can be divided into cobalt-based hardfacing wire and nickel-based hardfacing wire.

2) According to the structure of welding wire, it can be divided into solid-core welding wire and flux-core (also called tubular) welding wire.

3) According to the welding technology, can be divided into gas shielded arc welding, submerged arc welding, flame surfacing, plasma surfacing and spraying (welding) hardfacing wire.

Advantages

1) Cost saving. Surfacing a worn part to meet the requirement again can save 25%-75% of the cost than replacing the worn part;

2) Increase the service life of the work piece. Compared with no surfacing metal piece, the surfacing metal piece can increase the service life by 30%-800% in different degree depending on its service range.

Good Abrasion Resistance, impact wear resistance, adhesive wear resistance (intermetallic wear) , high temperature wear resistance, corrosion wear resistance and resistance to more than two types of composite wear.
