Elevated Temp Tensile Props for A242 T21 cast Al
Elevated Temp Tensile Props for A242 T21 cast Al
(OP)
Can anyone provide typical tensile yield and ultimate tensile properties for A242-T21 aluminum sand castings? Temperature range of interest is up to 400 deg. F. I have only found room temperature properties for that particular heat treatment. Application is a 1940s vintage aircracft engine head. Original spec was AMS 4222E
