Stellite20 Features at a Glance:
Stellite 20 Stellite alloy has excellent resistance to friction, cavitation, mortar abrasion and thermal wear. The alloy also has good corrosion properties. Even at a hot red temperature of 480, it has quite good hardness, strength and abrasion resistance.
Suitable for: shaft sleeves, rotating sealing rings, wear-resistant gaskets, bearing sleeves for pumps. Physical Properties: Hardness (HRC at room temperature): 57 Hardness (HRC at room temperature): 57 Stellite is a cemented carbide that can withstand various types of wear and corrosion and high temperature oxidation. Commonly known as cobalt-based alloys, Stellite alloys were invented in 1907 by the American Elwood Hayness. Stellite alloy is a class of alloys with cobalt as the main component, containing a considerable amount of nickel, chromium, tungsten and a small amount of molybdenum, niobium, tantalum, titanium, lanthanum and other alloying elements, and occasionally iron. Depending on the composition of the alloy, they can be made into welding wire, powder for hard surfacing welding, thermal spraying, spray welding and other processes, and can also be made into castings and forgings and powder metallurgy parts. Cobalt-based alloys are also known as Stellite alloys. It uses CO as the basic component and adds elements such as CR, W, C and other elements to the alloy. China's CO-based CR30W5 (cobalt-based No. 1), CO-based CR30W8 (cobalt-based No. 2), CO-based CR30W12 (cobalt-based No. 3), and CO-based CR28W20 (cobalt-based No. 4) belong to this category.
