The water nozzle (also referred to as a bushing) is divided into fixed and movable types, and it operates under extremely harsh working conditions. For instance, the medium contains solid particles, features strong impact, and has destructive effects such as abrasion, corrosion and impact. Thanks to its excellent corrosion resistance, wear resistance and impact resistance, Stellite alloy is often used for manufacturing pump and valve fittings.
