Nickel Alloy Incoloy 825 Pipes And Fittings Process performance and requirements:
Thermal processing
1, the appropriate heat processing temperature of 1150-900 ℃, the cooling method can be water quenching or rapid air cooling;
2, hot processing, the workpiece can be directly into the furnace has been warm. After the furnace to warm, the material holding time for each 100mm thickness of 60 minutes. Insulated to the specified time immediately after the baked, in the specified temperature range processing. If the temperature of the metal falls below the minimum processing temperature, it should be heated again;
3, after hot processing should be timely annealing to ensure the best corrosion resistance and the appropriate crystal structure.
Cold working
1, cold processing should be carried out after the solution treatment, processing hardening rate and austenitic stainless steel close to
This equipment should be adjusted accordingly.
2, in the cold processing capacity should be a large intermediate annealing process. The final stabilization is required when the final cold deformation is greater than 15%.
