Used as the small size of various flat, round spring, cushion spring, clockwork spring, can also produce spring ring, valve spring, clutch reed, brake spring and cold drawn steel wire, cold rolled coil spring. The wholesale supply 65Mn spring steel / Baosteel quality 65Mn spring steel to / 65mn alloy steel plate 65mn strength. Hardness. Flexibility and hardenability than 65 steel overheating sensitivity and tendency to temper brittleness, water quenching have a tendency to crack. Annealed machinability fair, cold plastic deformation, poor welding. Medium load plate spring, diameter 7-20mm coil spring and spring washer spring ring. High wear resistance parts, such as grinding machine spindle spring chuck. Precision machine tool screw. Cutter. Spiral roller bearing rings. Railway rail and other wholesale supply 65Mn spring steel / Baosteel of 65Mn quality spring steel / 65mn alloy steel plate [1 Use of a large number of low consumption 65Mn alloy round bar material and the acid in the pickling process, and some, mainly through the chemical reaction of the acid and iron, dissolved corresponding 65Mn low alloy round oxide dissolution to remove the iron. Some, such as sulfur suan 65Mn low alloy round steel pickling, but also by means of the low acid and 65Mn alloy round bar peeling effect generated by the chemical reaction of hydrogen bubbles to remove the oxide scale. Therefore, consume a lot of acid in the pickling process is inevitable. Although used in pickling acid inhibitor can reduce low-65Mn alloy round bar of metal consumption, but there is still a considerable amount of metallic iron lost. The the wholesale supply 65Mn spring steel / quality 65Mn spring steel in Baosteel / 65mn alloy steel plate [2] may reduce low alloy round bar 65Mn physical properties between low alloy round steel and acid pickling process, 65Mn chemical reaction and produce hydrogen. Since the chemical potential of hydrogen in the acid liquid is higher than the chemical potential of hydrogen in the pickling 65Mn low alloy round, the generated hydrogen will penetrate the steel and accumulates up caused by hydrogen embrittlement, thus affecting 65Mn low alloy round mechanical performance or subsequent processing. Wholesale supply 65Mn spring steel / Baosteel 65Mn quality spring steel / alloy steel plate 65mn [3] will bring a series of environmental pollution problems pickling process 65Mn low alloy round bar or part surface treatment, due to
