| ASTM A517 |
ASTM A517 Grade P in the standard A517/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 P need to be done the (Quenching + Tempering ) heat-treatment to meet the property requirement in the standard ASTM A517.
