65MN steel strip Introduction
The 65mn strength. Hardness. High flexibility and hardenability than 65 steel, with a thermal sensitivity and tendency to temper brittleness, water quenching the formation of cracks tendency. Annealed machinability can still be cold deformation plasticity, poor weldability. Under moderate load plate spring, diameter 7-20mm spiral springs and spring washers, spring ring. High wear resistance parts, such as the grinding machine spindle. Spring chuck precision machine screw. Cutter. Spiral roller bearing ring. Railway rail and so on.

65Mn density
    The 65Mn density ρ = 7.85 g / cc, the steel can be cold rolled into plate, strip and wire, production of the spring. 65Mn also produced such as fitter chisel, stylus and other tools. 65Mn steel can be made general cross-section dimensions of a small spring about 8 ~ 15mm variety of small size, such as flat, round spring, the bottom pad spring, spring winding.
