MIL AM350 Heat Treatments


  • Annealed: Heating to 1065°C+/-4°C and holding at temperature for 45 minutes per 25.4mm of thickness, followed by water quenching; Heat treated: Heating to 932°+/-4°C, held at heat for not less than 45 min. per 25.4 mm of thickness, quenched in water or otherwise quenched very rapidly to room temperature, cooled to -73°C or lower, held at this temperature for not less than 3 hours, warmed to room temperature, heated to either 538°C or 454°+/-12°C, held at temperature for not less than 3 hours nor more than 4 hours, and air cooled to room temperature.
  • Solution treatment at 1925°F. For Sheet and Strip, hold 3 minutes plus 1 minute for each 0.01 Inch thickness. Quench in water, oil or polymer; Austenitized (SCT) at 1710°C, hold 10 min. plus 1 min. for each 0.01 inch in thickness (+15min/-0 min) and quenched in water; Transformation treatment at -100°F, min. immediately after water quenching, after austenite conditioning. Minimum hold 180 min.
