| ASTM A517 |
ASTM A517 Grade E in the standardA517/A517M is a kind of high tensile alloy steel plates material used to fabric high temperature pressure vessels. ASTM A517 have six grades or levels. They are : Grade A, Grade B, grade E, grade F, grade J , grade P. ASTM A517 Grade E need to be done the (Quenching + Tempering ) heat-treatment to meet the property requirement in the standard ASTM A517.
Key words: A517 Grade E, ASTM A517 Grade E, A517 Grade E steel plate, ASTM A517 Grade E high tensile alloy steel plates, ASTM A517 Grade E for fabric high temperature pressure vessels
