Pressure vessel steel plate-A517 Grade E
Products Description
ASTM A517 Grade E Pressure vessel steel plate needs to be done with the (Quenching + Tempering ) heat treatment to meet the property requirement in the standard ASTM A517. ASTM A517 has six grades or levels. They are Grade A, Grade B, grade E, grade F, grade J , grade P. ASTM A517 Grade E in the standard A517/A517M is a kind of high-tensile alloy steel plate material used to fabricate high-temperature pressure vessels.
