Stellite Alloy of Shenyang New Industry Co.,LTD
Stellite Alloy
Stellite is a hard alloy that is resistant to all types of wear and corrosion and high temperature oxidation. Known as the cobalt-based alloy, stellite was invented in 1907 by American Elwood Hayness. Stellite alloys contain cobalt as a main component and contain a considerable amount of nickel, chromium, tungsten and a small amount of alloying elements such as molybdenum, niobium, tantalum, titanium and niobium, and occasionally iron. Depending on the composition of the alloy, they can be made into welding wire. The powder can be used for hard surface surfacing, thermal spraying, spray welding, etc., and can also be used for casting and forging parts and powder metallurgy parts.
Stellite
According to the classification of use, stellite alloy can be divided into stellite wear-resistant alloy, stellite high-temperature alloy and stellite wear-resistant and aqueous corrosion alloy. Under normal working conditions, in fact, it is both wear-resistant, high-temperature resistant, wear-resistant and corrosion-resistant. Some working conditions may also require high temperature resistance, wear resistance and corrosion resistance, and the more complicated it is. Under the circumstance, the more the advantages of the stellite alloy can be reflected.
Typical grades for Stellite are: Stellite 1, Stellite 4, Stellite 6, Stellite 12, Stellite 20, Stellite 31, Stellite 100, and the like. In China, the research on the stellite superalloy is mainly deep and thorough. Unlike other superalloys, the stellite superalloy is not reinforced by an ordered precipitate phase that is firmly bonded to the matrix, but consists of an austenitic fcc matrix that has been s
