Heat treatment Related

  • Annealing of JIS SUJ2 bearing steel

Slowly heated to 790-810 ℃ and allow enough times, let the steel to be thoroughly heated, Then cool slowly in the furnace. Different annealing ways will get different hardness.The SUJ2 bearing steel will get Hardness MAX 248 HB (Brinell hardness).

  • Quenching and temperature of JIS SUJ2 bearing steel

Heated slowly to 860°C, Then quenching by oil get 62 to 66 HRc hardness. High temperature tempering: 650-700℃,cool in air, get hardness 22 to 30HRC. Lowtemperature tempering: 150-170 ℃, Cool in ari, get 61-66HRC hardness.

  • Hot work and cold work of JIS SUJ2 bearing steel

JIS SUJ2 steel can hot worked at 205 to 538°C, SUJ2 Bearing steel can be cold worked using conventional techniques in the annealed or normalized conditions.


Mechanical Properties

The mechanical properties of annealed JIS SUJ2 bearing steel(typical for steel) are outlined in the table below:

Tensile Yield Bulk modulus Shear modulus Poisson’s ratio Thermal conductivity
MPa Mpa Gpa Gpa W/mK
520 415 Min 140 80 0.27-0.30 46.6


Applications

JIS SUJ2 steel is widely used for a variety of applications in the used to the bearings in rotating machinery. Typical applications such as valve bodies, pumps and fittings, the high load of wheel, bolts, double-headed bolts, gears, internal combustion engine. Electric locomotives, machine tools, tractors, steel rolling equipment, boring machine, railway vehicle, and mining machinery transmission shaft on the steel ball, roller and shaft sleeve, etc.
