PROPRIETARY Permodur 4724 Heat Treatments
- Optimal material properties are realised after annealing by holding in the temperature range 800-860°C, followed by rapid cooling in air or water; A slight tendency for grain growth and embrittlement exists at above temperatures of 950°C. It must be noted that any properties that are adversely affected by grain coarsening occurs cannot be recovered by simple thermal treatments. The moderate chromium content and fully ferritic microstructure of this steel makes it susceptible to 475 embrittlement when held at temperatures within the range 400-550°C. Slow heating or cooling through this temperature range should thus be avoided. The effects of 475 embrittlement can be reversed by briefly heating to within the temperature range 700-800°C. This steel is also susceptible to embrittlement by sigma phase formation within the temperature range 600-800°C over long periods of time. The effects of sigma phase formation may be reversed by heating to above 1050°C to take all of the sigma phase into solution again.
