Are there any specific heat treatment requirements for ASTM A285 grade A

ASTM A285 grade A steel does not have specific heat treatment requirements outlined in the standard specification. A285 grade A is a low to intermediate tensile strength carbon steel plate primarily used for moderate to low-pressure vessel applications.

The standard ASTM A285/A285M specifies that the plates are to be supplied in a normalized or stress relieved condition. Normalizing involves heating the steel plate to a temperature above the critical range and then cooling it in still air. Stress relieving, on the other hand, involves heating the material to decrease residual stresses and improve dimensional stability.

However, these heat treatments are typically carried out by the manufacturer or as per customer requirements. The specifics of the heat treatment process (e.g., temperatures, holding times) may be determined based on factors such as plate thickness, desired mechanical properties, and fabrication considerations.

It is essential to consult the material's manufacturer or follow the applicable codes, standards, and project specifications for any specific heat treatment requirements for ASTM A285 grade A plates.
