Spot 65Mn spring steel price

65Mn low-alloy steel bar must be with a high elastic limit and a high yield ratio, in order to avoid permanent deformation of spring steel under high load; also require good hardenability and low decarburization sensitivity, the elastic limit significantly reduced; and good surface quality, easy processing and good forming heat treatment process of the hot and cold state. In the thermal state of the spring forming thermoforming spring steel heat treatment process. In this way most of the spring steel molding thermoforming and combined together for the heat treatment, while most of the coil spring steel is heat-treated after thermoforming. This spring steel heat treatment is quenching and tempering, heat treatment is tempered prop's body. Elastic limit and limit high yield of such organizations, and a certain toughness. Adopt new ideas and methods to carry out innovative stability control technology development of the formation mechanism of the easiest in the "0.4 seconds" time resulting "rolling break, flick" issues such careful analysis, to reduce the damage from the roll carry, reducing tail deviation, and other aspects of the work, after more than three years to develop a software program to track testing, assessment, analysis to determine reasonable parameters. 65Mn steel strength, hardness, elasticity and hardenability than 65 steel high with thermal sensitivity and tendency to temper brittleness, water quenching have a tendency to form cracks. Annealed machinability still, cold plastic deformation is low, poor welding. Under moderate load plate spring, 7-20mm diameter coil spring and spring washer spring ring. High wear parts, such as grinding machine spindle, collet chuck, precision machine screw, cutter, rings spiral roller bearings, railway rails, etc. Spring steel: 65 70 85 65Mn 55SiMnVB 60Si2Mn 60Si2MnA 60Si2CrA 55SiCrA 60Si2CrVA 55CrMnA 60CrMnA 50CrVA 60CrMnBA 30W4Cr2VA Dongguan Green spot price of steel a lot of complete quality assurance specifications tons wholesale Guangdong region; cash on delivery courier company can collect, the amount available for free delivery, provinces and shipping, delivery by courier logistics company, Dongguan Green steel company look forward to your trust and long-term cooperation.
