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. Wholesale supply cold 65Mn the Baosteel 65Mn spring steel 65mn strength, hardness, elasticity 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. Railroad rails and other wholesale supply cold-rolled 65Mn Baosteel 65Mn spring steel [1] consume a lot of 65Mn low alloy round steel material and an acid in the pickling process, and some by the chemical reaction of the acid and iron, dissolving the 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. 65Mn spring steel the wholesale supply cold 65Mn Baosteel [2] may reduce low alloy round steel 65Mn physical properties of a chemical reaction between the low alloy round steel and acid pickling process, 65Mn 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. The wholesale supply cold-rolled 65Mn Baosteel 65Mn spring steel [3] will bring a series of environmental pollution problems in the pickling process of 65Mn low alloy round bar or part surface treatment, due to 65Mn low alloy round steel varieties, product specifications and of scale in production of the same, resulting in a great differential in the production equipment and production environment
