A517 Grade H High strength steel plate,astm a517 grade h

Pressure vessel steel plate and sheet A517 Grade H is under the standard ASTM A517/A517M. A517 Grade H is a high strength quenched and tempered alloy steel plates intended for use in fusion welded boilers and other pressure vessels.

Specification we can supply:
Thickness: 8mm to 150mm
Width: 1500mm to 4200mm
Length: 4000mm to 18000mm

Chemical Composition and Mechanical Property:

A517 Grade H is a high strength steel plate with the minimum yield strength at 690Mpa for the thickness equal or belows 65mm,and 620 Mpa for the thickness above 65mm,the tensile strength shall be within 795-930 Mpa. The manufacturer may reheat-treat plates that fail to meet the mechanical property requirements of this specification when rolling of high tension steel plate A517GrH.All mechanical property tests shall be repeated whenmaterial is resubmitted for inspection.

we are specialized in super thick low alloy, high strength steel plate and cooperated with ABS, BV, DNV, CCS, GL, LR, KR, NK, and RINA Classification Society to approve the super thickness plate to 300mm now.If you have any inquiry in steel price or technical conditions, please contact us freely by email or chat with our liveperson!
