GB 20CrMnTi bearing/Gearing steel is GB standard Alloy Carburizing Bearing/Gearing steel, GB 20CrMnTi properties is a chromium, manganese, titanium alloy steel specification. 20CrMnTi is equivalent with others standard bearing/Gearing steel, gearing steel. 20crmnti steel properties as below:
Related Specifications ASTM A29/A29M GB EN 10083/3 JIS G4053 GB GB/T GB/T 3077-1988
Form of Supply
GB 20CrMnTi bearing/Gearing steel, we can supply the round bar, steel flat bar, plate, hexagonal steel bar and steel square block. GB 20CrMnTi steel Round bar can be sawn to your required lengths as one offs or multiple cut pieces. 20CrMnTi bearing/Gearing steel Rectangular pieces can be sawn from flat bar or plate to your specific sizes. Ground tool steel bar can be supplied, provide a quality precision finished bar to tight tolerances.
Chemical composition
| C(％) | 0.95～1.05 | Si(％) | 0.15～0.35 | Mn(％) | 0.25～0.45 | P(％) | ≤0.025 |
| S(％) | ≤0.025 | Cr(％) | 1.40～1.65 |
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 20CrMnTi bearing/Gearing steel will get Hardness MAX 248 HB (Brinell hardness).
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.
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 bearing/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
GB 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 shaft sleeve, etc. 20crmnti steel properties as below:
