Product Description

Product Description
Introduction LORK is a alloy manufacturer with 20 years of manufacturing experience.

Stellite 6b/Cobalt Alloy 6b/UNS R30016
Cobalt alloy 6b / Stellite 6b is a cobalt-based, chromium-tungsten alloy used extensively in wear environments where its low friction coefficient minimises the risk of seizing and galling, even in applications where lubrication is not practical. Stellite 6b is supplied in the solution treated condition (to AMS 5894) and its wear resistant properties inherent in this state limit the amount of heat treating and post machining. Typical applications for Alloy 6b include chain saw guide blades, furnace fan blades, high temperature bearings, valve stems, food processing equipment and steel mill equipment.
Cobalt Alloy Stellite 6b Applications
▪ Chain saw guide bars▪ Furnace fan blades▪ Steam turbine erosion shields▪ High temperature bearings▪ Food processing equipment▪ Centrifuge liners▪ Valve stems▪ Needle valves▪ Nozzles▪ Hot extrusion dies▪ Extruder screws▪ Forming dies▪ Pump plungers▪ Valve parts
