Iso 17cr2ni2mo Structural Alloy Steel Round Bar Used For Gear Wheel
The 17CrNiMo6 is the standard steel number of DIN 17210 - (86) in
Germany, and the European standard is 18crnimo7-6, which
corresponds to the 17Cr2Ni2Mo of GB 17Cr2Ni2Mo is not a GB
material, but a JB material.The specific standard number is: JB/T
6395-2010 large gear, tooth ring forging Differences between
17CrNiMo6 and 20CrMnTi.
17Cr2Ni2Mo Steel Mechanical:
| Yield Rp0.2 (MPa) | Tensile Rm (MPa) | Impact KV/Ku (J) | Elongation A (%) | Reduction in cross section on fracture Z (%) | As-Heat-Treated Condition | Brinell hardness (HBW) |
|---|---|---|---|---|---|---|
| 819 (≥) | 951 (≥) | 31 | 14 | 22 | Solution and Aging, Annealing, Ausaging, Q+T,etc | 413 |
17Cr2Ni2Mo Steel Physical:
| Temperature (°C) | Modulus of elasticity (GPa) | Mean coefficient of thermal expansion 10-6/(°C) between 20(°C) and | Thermal conductivity (W/m·°C) | Specific thermal capacity (J/kg·°C) | Specific electrical resistivity (Ω mm²/m) | Density (kg/dm³) | Poisson’s coefficient, ν |
|---|---|---|---|---|---|---|---|
| 32 | - | - | 0.31 | - | |||
| 296 | 927 | - | 34.3 | 124 | - | ||
| 582 | - | 13 | 32.2 | 314 | 222 |
17CrNiMo6 is much more resilient.The carbon content is different,
the alloy element is different, the mechanical property is
different.The thermal process is also different.The previous
performance is superior, and the latter gearbox gear and
differential gear are widely used.
