Ovako 225 is a steel specially designed for nitriding but is also suitable for carburizing or applications requiring quenched and tempered steels.
- High nitriding rate
- Suitable for nitriding, case carburizing or quench and tempering
- Also suitable for applications require quenched and tempered steel in bars with diameter 25-160 mm.
- Weldable under certain conditions
Variant 225A - Standard quality
Variant 225C - With a reduced sulphur content for a reduced number of sulphide inclusions
