Grade Comparison: 420 / 420J1 / 420J2
| Grades | Углерод | Hardness After Heat Treat | Key Feature |
| 420 | 0.15 – 0.40% | ~45–55 HRC | Balanced overall, general engineering |
| 420J1 | 0.16 – 0.25% | ~40–50 HRC | Better corrosion & ductility |
| 420J2 | 0.26 – 0.40% | ~50–55 HRC+ | Higher hardness & wear resistance |
Carbon content is the main differentiator—higher carbon gives higher hardness and wear resistance, while lower carbon improves corrosion resistance and workability.
