The need for superior wear resistance and longer component life has positioned Deloro Stellite as a leading manufacturer and supplier of Cobalt based finished machined components or welding consumables used extensively in the Oil and Gas Industry.
The use of Cobalt base alloys, such as STELLITE® 6; 12; 21 and 6B, in the manufacturing of LWD (logging while drilling) and MWD (measurement while drilling) tools has provided Oil Field Service Providers with reliable, durable cast and finished machined parts that have proved to extend the service life of critical components.

In addition to the Cobalt based alloys, vacuumed cast components made from Nickel based alloys have also been used extensively for their strong mechanical properties.
