A517 GrB steel plate Introduction
ASTM A517 Grade B 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 B need to be done the (Quenching + Tempering ) heat-treatment to meet the property requirement in the standard ASTM A517.
A517 GrB Steel plate Application
Alloy steel plate A517 Grade B is mainly used to manufacture pressure vessels and boilers and pressure tanks for liquid materials.
