Heat Treatment
| HEAT TREATMENT | TEMPERATURE |
|---|---|
| Soft Annealing | 870°C / 2h, Cool slowly at a rate of 15 °C per hour up to 540°C. it can be continued to cool in open air. Result hardness: BHN 225-248. |
| Stress Relieving | 595-700°C / 2h |
| Hardening | Pre-heating: 620-650°C, 810-845°C, 930-955°C austenitizing 1010°C - 1120°C High pressure gas (at least 4 bar pressure) should be cooled up to 700°C. |
| Tempering | 540-595°C x 2 Tempering If EDM and PVD is to be done, at least 3 times tempering is needed. |
