G80 diameter of 16mm or less above grade Lifting chain 20Mn2,16mm using 25 Vanadium. g80 level lifting chain lifting chain is a high strength, high-intensity lifting chain is made of high-strength manganese steel, and 80 lifting chain just is made of high strength manganese steel, so He said 80 is a high-intensity lifting chain lifting chain. g80 level lifting chain automatic equipment from Germany, IF chain after heat treatment and strict control by the various testing equipment to ensure that G80 lifting chain, g80 level lifting chain with high intensity lifting chain made of manganese steel specifications , the production process in strict accordance with ISO3077, EN818, AS2321 production standards, chain ensure safety factor of 4 times the price of lifting chain, 2.5 times the test load. 80 lifting chain surface can be polished, black, dipping, hanging plastic, electroplating and other processing to accommodate large moisture, acidic or slightly alkaline and other harsh environments. Chen Force chain of surface treatment methods are polished, black, galvanized, seepage nickel. Polishing known as tumbling into the roller chain is to use the chain itself in the role of friction, so as to achieve the purpose of rust, chain color polished as steel qualities. After blackening known black cook, the chemicals into the black pool filled with water, heating, when the temperature reaches a certain extent, into a chain of polished and continue to heat a certain time, the chain will be formed on the surface of a layer of black oxide layer. This layer of oxide layer stable chemical properties, storm drain in the air if not a chemical reaction lifting chain, so as to effectively protect the main chain. At present most of the black market chain demand chain. White zinc plated and galvanized into color zinc plating, galvanizing process is mainly galvanized, galvanized chain looks beautiful, but in a wet environment, the surface prone to chemical reaction to produce white alkaline substances. Infiltration of nickel chain is the chain's surface nickel molecules penetrate into the chain, the chain beautiful nickel surface infiltration lifting chain spreader, a bit like the color of stainless steel, and stable performance, easy chemical reaction in the outdoor environment, and because of infiltration all aspects of nickel on the environment without any pollution, it is a surface treatment currently China has strongly advocated currently the industry can do this only chen surface treatment.
