Heat Treatments

  • <b>Annealing:</b> 750 to 800°C / Controlled slow cooling in furnace (10 to 20°C/h) to approx. 600°C air cooling. <br><b>Stress relieving:</b> 600 to 650°C, slow cooling in furnace. Slow cooling in furnace; intended to relieve stresses set up by extensive machining, or in complex shapes. After through heating, hold in neutral atmosphere for 1 to 2 hours. <br> <b>Hardening:</b> 1070 to 1150°C, oil, salt bath (500 to 550°C), air. Holding time af temperature equalization: 15 to 30 minutes.<br> <b>Tempering:</b> Slow heating to tempering temperature immediately after hardening/time in furnace: 1 hour for every 20 mm of work piece thickness, but not less than 2 hours/ air cooling (minimum holding time: 1 hour):;<br>1<sup>st</sup> tempering tempering approx. 30°C above maximum secondary hardness<br>2<sup>nd</sup> tempering to desired working hardness<br>3<sup>rd</sup> tempering for stress relieving. 30 - 50°C below highest tempering temperature
