A 514 changes at what temperature

RE: A 514 changes at what temperature
For ASTM A 514 Grade H steel (high yield, Q&T), above 400 deg F to 1100 deg F you will see a reduction in mechanical properties while at elevated temperature; cool to RT and properties are back to near original.
Exposure to temperatures above 1150 deg F (original minimum tempering temperature by specification) will have a step change to lower mechanical properties and upon cooling to RT will be a permanent change (lowered) to these properties unless this material is reheat treated.
RE: A 514 changes at what temperature
Also, does anyone have any experience requenching and tempering A514 or working with green material prior to Q&T (not sure if this is even possible to get)?
Thanks
RE: A 514 changes at what temperature
You can easily reheat treat this material to achieve the desired mechanical properties after hot forming.
