Heat treatment Related
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 GCr15 bearing steel will get Hardness MAX 248 HB (Brinell hardness).
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. Low temperature tempering: 150-170 ℃, Cool in ari, get 61-66HRC hardness.
GB GCr15 steel can hot worked at 205 to 538°C, GCr15 Bearing steel can be cold worked using conventional techniques in the annealed or normalized conditions.
Mechanical Properties
The mechanical properties of annealed GB GCr15 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
GB GCr15 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.
