65Mn High Pressure Cold Rolled Steel Sheet Plate Customized

65Mn Product Introduction

After heat treatment and cold drawing hardening, the strength is relatively high, with certain flexibility and plasticity; The fatigue limit is similar to that of multicolored alloy spring under the same surface condition and full quenching. But hardenability is very poor, mainly used for smaller size springs, such as pressure regulating speed regulating spring, force measuring spring, general machinery on the round, square spiral spring or wire as small machinery spring.

65Mn Heat Treatment

65Mn low alloy round steel must have high elastic limit and high compressive strength ratio to avoid permanent deformation of spring steel under high load. At the same time, it also requires good hardenability and low decarbonization sensitivity, so that the elastic limit is greatly reduced; And good surface quality, easy to process in hot and cold state and good heat treatment process.
Heat treatment process of spring hot forming spring steel formed in hot state. Most spring steels are formed in this way by combining thermal forming with heat treatment, while most spiral spring steels are formed after thermal treatment. The heat treatment of the spring steel is quenching + medium tempering, and the structure of the spring steel after heat treatment is tempered tortenite. This kind of structure has high elastic limit and yield limit, and has certain toughness.
Using new ideas and methods, innovative development of stability control technology to the most easy in the "0.4 seconds" time of "rolling broken, tail swing" and other problems formation mechanism was carefully analyzed, from reducing roll damage, reduce tail deviation and other aspects of work. After more than 3 years of software program development, tracking test, evaluation, analysis to determine the reasonable process parameters.
The strength, hardness, elasticity and hardenability of 65Mn steel plate are higher than that of no. 65 steel, with overheating sensitivity and temper brittleness tendency, water quenching has a tendency to form cracks. Annealing state machinability is fair, cold deformation plasticity is low, poor weldability. Plate springs subject to medium load, 7-20mm diameter coil springs and spring washers. Spring ring. High wear resistance parts, such as grinder spindle, spring clamp, precision machine tool screw, cutter, ring on spiral roller bearing, railway rail, etc.
