65mn钢板具有过热敏感性、和回火脆性。水淬具有形成裂纹倾向，退火后可切削性尚可，冷变形塑性差，受中等载荷的板弹簧，直径达7-20mm的螺旋弹簧及弹簧垫圈、弹簧环。高耐磨性零件，如磨床主轴、弹簧卡头、精密机床丝杆、切刀、螺旋辊子轴承上的套环、铁道钢轨等。

The 65mn steel plate has overheating sensitivity and tempering brittleness.Water quenching has the tendency to form a crack, cutting after annealing, cold deformation plasticity is poor, by moderate load plate spring, diameter of 7-20mm spiral spring and spring washer, spring ring.High wear resistance parts, such as grinder spindle, spring clip head, precision machine tool wire rod, cutter, sleeve rings on spiral roller bearing, railway rail, etc.

65mn冷轧钢带热处理及冷拔硬化后，强度比较高，具有一定的柔韧性和可塑性；相同表面状态和完全淬透情况下，疲劳极限与五彩合金弹簧相当。但淬透性非常差，主要用于较小尺寸的弹簧，如调压调速弹簧、测力弹簧、一般机械上的圆、方螺旋弹簧或拉成钢丝作小型机械上的弹簧。

After 65mn cold rolled steel strip heat treatment and cold pull hardening, the strength is relatively high and has certain flexibility and plasticity; the fatigue limit is comparable to the colorful alloy spring under the same surface state and complete quenching.But quenching is very poor, mainly used for the smaller size of the spring, such as pressure regulating speed spring, measuring spring, general mechanical circle, square spiral spring or pulled into steel wire as a small mechanical spring.

65mn钢板强度、硬度、弹性和淬透性均比65号钢高，具有过热敏感性和回火脆性倾向，水淬有形成裂纹倾向。退火态可切削性尚可，冷变形塑性低，焊接性差。 受中等载荷的板弹簧，直径达7-20mm的螺旋弹簧及弹簧垫圈.弹簧环。高耐磨性零件，如磨床主轴、弹簧卡头、精密机床丝杆、切刀、螺旋辊子轴承上的套环、铁道钢轨等。

The strength, hardness, elasticity and quenching of 65mn steel plate are higher than those of 65 steel, which has overheat sensitivity and tempering fragility, and water quenching forms crack.The annealing state is cutting, low cold deformation plasticity and poor welding.Medium load plate springs, coil springs of 7-20mm diameter and spring washers. spring eye.High wear resistance parts, such as grinder spindle, spring clip head, precision machine tool wire rod, cutter, sleeve rings on spiral roller bearing, railway rail, etc.
