I recently received several plates of ASTM A709, Gr.50, Normalized Rolled steel. The material certs were provided with the steel and Charpy V Notch values were provided from the steel mill on the material certs. The CVN test were performed at -40c, at the mill. The results listed on the material cert were extremely high from what I have ever seen (ranging around 270ft/lbs). Are the results "typical"? What would "typical" CVN results be for ASTM A709, Gr.50, non-normalized plate be?
And yes, I realize all of the above varies from plate to plate and even from mill to mill, this is why I stress "typical" CVN results.
