  1: 65Mn steel introduction
      65Mn steel is a Chinese GB standard spring steel grade. Its strength, hardness, elasticity and hardenability are higher than that of 65# steel, but it has superheat sensitivity, easy to produce quench crack and temper brittleness. The annealed state has good machinability, and the cold deformation plasticity is low, but the weldability is poor.

  4: 65Mn steel mechanical properties  

      The mechanical properties mainly include tensile strength, yield strength, elongation, area or reduction, hardness, impact value, non-metalic inclusion etc. Different heat treatment, the mechanical properties will be different, such as normalized, tempered, QT. If you want to know the properties, kindly contact the salesman.

  Application	65Mn high carbon steel is mainly used in the manufacture of various small-section flat springs, round springs, clockwork, etc. It can also be used to manufacture spring rings, valve springs, shock absorbers, clutch reeds and brake springs, regulating speed regulating spring, spring load, general machinery in the round, square spiral spring or pull wire for small mechanical spring.

   

  6. Heat treatment Related
  Annealing
      At first Slowly heated to 730 ºC and allow enough times, let the steel to be thoroughly heated, Then cool slowly in the furnace. Then 65Mn tool  steel will get MAX 250 HB (Brinell hardness).
  Hardening 
      At the beginning, 65Mn steels should be heated uniformly to 830-860°C (1526-1580°F) until completely heated through. After about 30 min per 25 mm of ruling section is to be provided and then the steels should be immediately quenched in oil. 

  Tempering
      65Mn steels is performed at 540°C, Soak well at the selected temperature and soak for at least one hour per 25mm of total thickness. Hardness values at different temperatures after tempering.

   

   

  7: Delivery condition

      For hot forged rolled bar, usually the delivery condition is hot forged or rolled, annealed/QT, rough turned/Black surface.
      For hot forged or hot rolled bar, usually the delivery condition is hot rolled, annealed/QT, Black surface.
      For hot forged plate, usually the delivery condition is hot forged, annealed/QT, milled surface/Black surface

      For hot rolled plate, usually the delivery condition is hot rolled, annealed/QT, black surface.
