热处理
- Heat treated at 350-400°C; Duration: 30 min to 1h; Air cooling; The optimum heat treatment conditions may be very different. The spring manufacturer shall choose those conditions answering the purpose; The heat treatment data refer to compression springs, torsion and tension (springs without initial tension).
- Hot working (air cooling): 1150-850°C; +AT - Solution annealing (air or water cooling): 1000-1100°C.<br><br>Hot formed conditions:<br>1U - Hot formed, not heat treated, not descaled.<br>1C - Hot formed, heat treated, not descaled. <br>1E - Hot formed, heat treated, mechanically descaled. <br>1D - Hot formed, heat treated, pickled, coated (optional).<br>1X - Hot formed, heat treated, rough machined.<br>1G - Hot formed, heat treated, descaled, rough machined or shaved in the case of rod. <br>Cold processed conditions:<br>2H - Finishes 1E, 1D or 1X, cold processed, coated (optional).<br>2D - Finish 2H, heat treated, pickled and skin- passed (optional), coated (optional). <br>2B - Finishes 1E, 1D or 1X, cold processed, mechanically smoothed. <br>2G - Finishes 2H, 2D or 2B, centreless ground, mechanically smoothed (optional). <br>P - Finishes 2H, 2D, 2B or 2G, specular polishing.
