A517 Grade H steel plate is used for pressure vessel. ASTM A517 Gr.H is a kind of high strength steel material. A517 Gr.H delivery condition is Q+T (Quenched + Tempered ) heat-treatment. A517 Grade H is also can be called alloy steel plates for high temperature boiler and pressure vessel, because it has the property of high temperature resistance.
A517 Grade H is a high strength steel plate with the minimum yield strength at 690Mpa for the thickness equal or below 65mm,and 620 Mpa for the thickness above 65mm,the tensile strength shall be within 795-930 Mpa.
ASTM A517 Grade H application :
A517 Grade H pressure vessel steel is widely used in petroleum, chemical industry, power station, boiler, etc, used to make the reactor, heat exchanger, separator, liquefied gas, nuclear reactor pressure vessel and etc.
