65Mn弹簧钢易过热,注意加热温度和保温时间。建议加热820度,适当保温。回火温度:320度时间要充分。
硬度:45-48HRC.使用性能较好。
65Mn钢带的标准:
65mn弹簧钢带执行标准:GB/T 1222-2007
65Mn弹簧钢,锰提高淬透性,φ12mm的钢材油中可以淬透,表面脱碳倾向比硅钢小,经热处理后的综合力学性能优于碳钢,但有过热敏感性和回火脆性。用作小尺寸各种扁、圆弹簧、座垫弹簧、弹簧发条,也可制作弹簧环、气门簧、离合器簧片、刹车弹簧及冷拔钢丝冷卷螺旋弹簧
65Mn原材料的洛氏硬度:
1、热轧硬度:240~270HB
2、冷轧软态硬度:190~220HB
3、冷轧硬态硬度:300~340HB
4、热处理硬度:38~60HRC
65Mn弹簧钢带规格:
盘圆:Φ5.5~16mm 轧材:Φ16~160mm 锻材:Φ160~450mm
硬度.弹性和淬透性均比65号钢高,65MN钢带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
