Heat Treatment
  • Annealing of 65Mn Spring Steel: Slowly heated to 730°C and allowed sufficient time for thorough heating, then cooled slowly in the furnace. Resulting hardness: MAX 250 HB.
  • Hardening of 65Mn Spring Steel: Heated uniformly to 830-860°C (1526-1580°F) until completely heated through. Provide about 30 min per 25 mm of ruling section, then immediately quench in oil.
  • Tempering of 65Mn Spring Steel: Performed at 540°C. Soak well at selected temperature for at least one hour per 25mm of total thickness.

Applications
65Mn steel, after heat treatment and cold drawing hardening, exhibits high strength with certain toughness and plasticity. In surface hardening cases, it achieves complete fatigue limits comparable to alloy spring steel. However, hardenability is poor, making it mainly suitable for smaller size springs such as regulating speed springs, load springs, round and square spiral springs in general machinery, or pull wire for small mechanical springs.
Regular Size and Tolerance
Steel round bar: Diameter Ø 2mm - 3000mm
Steel plate: Thickness 2mm - 3000mm x Width 100mm - 3500mm
Steel Hexagonal bar: Hex 5mm - 105mm
Other 65Mn sizes not specified - please contact our experienced sales team.
