Heat treatment Related
- Annealing of 20CrMnTi Alloy Gearing 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 20CrMnTi Gearing
steel will get Hardness MAX 248 HB (Brinell hardness).
- Quenching and temperature of 20CrMnTi gear steel
Heated slowly to 788°C, Then put in salt-bath furnace keep 1191 ℃to
1204 ℃.quenching by oil get 60 to 66 HRc hardness. High temperature tempering: 650-700℃,cool in air, get hardness 22 to 30HRC. Low temperature tempering: 150-200 ℃, Cool in ari, get 61-66HRC hardness.
- Hot work and cold work of 20CrMnTi Alloy Gearing steel
GB 20CrMnTi steel can hot worked at 205 to 538°C, 20CrMnTi Bearing/Gearing steel can be cold worked using
conventional techniques in the annealed or normalized conditions.
Mechanical Properties
The mechanical properties of annealed GB 20CrMnTi Gearing 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
20CrMnTi steel is widely used for a variety of applications in the
used to the bearing/Gearings 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
