Unless otherwise stated, all the above values are typical at room temperature.

 A  Rotary Bend Test 5 x 108 Cycles

 B Rotating Beam Fatigue Test In Accordance With DIN50113. Stress quoted corresponds to 5 x 107 Cycles. Values are considered  conservative.

 C At 68 ° F (20 ° C)

 D At 100 ° - 300 ° C (212 °- 572 ° F)

 E Elastic modulus varies with stress level. Use values given as approximate only.

 F ASTM E23 0.25" Unnotched die cast test bar

 G 0.1% Offset

 H 0.5% Compressive Yield strength As-Cast cold chamber

 I Notched Charpy

 J 0.1% Offset

 K Compressive Strength

 L Maximum service temperatures are subject to creep limitations.

 M Dependent on application
