PROPRIETARY ExELL 15-5 PH Heat Treatments

  • Stress relieving:After aging is generally not performed because of the risk of undesired aging. Stress relieving will simultaneously age harden the material. Thusit is very useful to perform major machining in the solution annealed condition, then age the part asrequired. The aging treatment in this context will both precipitation harden and stress relieve the material.
    Solution annealing: Should not be necessary. If aged material requires to be re-solution annealed treat as follows: Heat to 1900°F (1038°C), equalize, hold 30 minutes at temperature and air quench. Movement and distortion are likely. Resulting hardness will be ~30-33 HRC. Age hardening: If was not supplied in a specific aged condition (prehardened), the material can be age hard-ened with an aging temperature generally between 925°F (496°C) and 1150°F (621°C). The aging temperature is typically selected to attain a desired hardness level.
    Condition H925, aging temperature: 925°F (496°C), Hardness (HRC) ~42-44;
    Condition H975, aging temperature: 975°F (524°C), Hardness (HRC) ~39-41;
    Condition H1025, aging temperature: 1025°F (552°C), Hardness (HRC) ~38-40;
    Condition H1150, aging temperature: 1150°F (621°C), Hardness (HRC) ~33-35.
    Age hardening: Aging is performed by uniformly heating to the aging temperature, equalizing temperature from surface to center, holding 4 hours at temperature and air cooling. Slight shrinkage will occur after aging on the order of about 0.0005 (0.0127 mm) to 0.0010 (0.0254 mm) inches per inch. Most aging is accomplished by using a 975°F (524°C) age or higher. A 975°F (524°C) aging treatment is used for a certain balance of hardness and toughness while higher temperature aging treatments will improve toughness and minimize over-aging if higher service temperatures are encountered.
