WokaDur NiA-Tube is pure nickel tubular welding rod filled with blocky, cast and crushed tungsten carbide (CTC). It is designed for application using Gas Tungsten Arc Welding on ferritic and austenitic steel substrates, as well as cast steels with a maximum carbon content of 0.5%. The carbide hardness ranges from 1900 to 2300 HV0.1. It is an excellent choice when exceptional wear resistance combined with corrosion protection is desirable. WokaDur NiA-Tube meets DIN EN 14700: T Ni20.
