ASTM A517 Grade H quenched and tempered alloy steel plate is a kind of high strength steel material. A517 Grade H is used for pressure vessel.A517 Gr.H delivery condition is Q+T (Quenched + Tempered ) heat-treatment. A517 Grade H steel plate is also can be called alloy steel plates for high temperature boiler and pressure vessel, because it has the property of high temperature resistance.
