Cobalt Based Alloy Chrome Alloy By CNC Machining Precision Casting Machinery Metal
Product Description
Castings are metal forming objects obtained by various casting methods, that is, the smelted liquid metal is injected into the pre-prepared casting mold by pouring, pressing, inhaling or other casting methods, and after cooling, grinding and other subsequent processing means, the objects with certain shape, size and performance are obtained.
cobalt based alloy/stellite alloy is a range of cobalt-chromium-tungsten alloys designed for wear resistance, corrosion resistance and high termal resistance. It has excellent wear and corrosion resistance performance at relatively high temperature. It is widely used in oil&gas, metallurgy, machinery, wood cutting, automotive, paper and food processing industries etc.
