heat treatment

Normalizing 18CrNiMo7-6/1.6587
1. Nominal normalizing temperature: 840-890°C
2. Keep warm for several hours
3. Cool in air

18CrNiMo7-6/1.6587 annealed
1. Nominal annealing temperature: 630-650°C
2. Slowly cool in the furnace
3. The maximum Brinell hardness is 229

18CrNiMo7-6/1.6587 quenched and tempered (QT)
1. Nominal hardening temperature: 830-865°C
2. Keep at this temperature and then quench in oil
3. Temper as soon as possible when the temperature is as low as the ambient temperature
4. Carefully heat the steel to the appropriate temperature selected with reference to the tempering chart or table
5. Usually the tempering temperature is 600°C, depending on actual requirements
6. Put the material out of the furnace and let it cool in the air
