PEDROTTI MECCANICA www.pedrotti.it 8 Tool steel with high workability and micro structural consistency Features: Good machinability Good weldability Good dimensional stability and wear resistance Ideal for polishing and texturing Uniform hardness less than 207HB Stress relieving Prior to processing, all 1.1730 steel plates are stress relieved in order to reduce internal stresses and to create the best con- ditions for processing with limited deformation. All materials are heat treated in a bell furnace (capacity 50 t). The heat treated part is kept at temperature (580°c) for at least 5 hours and is slowly cooled, with a ramp of 35°c/h, to room temperature (see the graph shown in figure 1).
