5 BENEFITS OF STELLITE WELDING IN MACHINING

Hardness

Stellite as a metal is extremely strong, which makes machining difficult and increases lead times and costs. Using the HVOF method we can give components that have Stellite 6 attributes without this cost. www.gemsons.com

Corrosion Resistance

Stellite welding provides excellent resistance to corrosion. This is due to the inherent characteristics of the hard carbide phase dispersed in an alloy matrix which allows Stellite coatings even at high temperatures to retain their corrosion resistance properties. Stellite similar to stainless steels corrodes mainly through a pitting process and not by a general loss of mass in solutions to seawater and chloride.

Wear Resistance

Stellite is the industry standard for most wear resistance for general purposes. There are several ways of mechanical damage to this. Stellite coatings have a high hardness of up to 500 ° C. Stellite would also have strong impact resistance and erosion in the cavitation.

Alternative Welding

Components are also hard-faced by the welding process with Stellite. The downside of this method is that the Stellite layer will often break as temperature changes occur and would not occur with sprayed Stellite. Even, HVOF can be performed without fear of thermal distortion.

Applications

Stellite has a wide variety of applications but is most common with our valve customers, where it is mostly used as a substitute for Electroless Nickel Plating where it is difficult to achieve the same degree of hardness and corrosion resistance. It is also used for machines in a variety of movable sections.
