PROPRIETARY AM350 Heat Treatments

  • To develop the high precipitation hardened strength of the alloy by heat treatment, starting from Condition H, heat treatments are done to accomplish two necessary steps. The first is a heat treatment which allows the relatively stable austenite of Condition H to transform to martensite (Austenite Conditioning and Transformation). The second is a precipitation hardening heat treatment to further strengthen the material. The austenite is easier to transform to martensite using a lower temperature heat treatment. For this reason, Condition DA uses a 760°C (1400°F) heat treatment to produce a martensite transformation around room temperature, and this is followed by a precipitation hardening heat treatment at 565°C (1050°F). If Condition SCT 850 is desired, the austenite conditioning heat treatment is conducted at ~925°C (~1700°F). In this case, the martensite transformation is not complete until the material is held for some time at -73°C (-100°F). When the transformation is complete, the material is precipitation hardened at 455°C (850°F) to Condition SCT 850.
