Product Description:
1.2 Plates under this specification are available in four
grades having different strength levels as
follows:
Tensile Strength, ksi [MPa]
55 [380] 55–75 [380–515]
60 [415] 60–80 [415–550]
65 [450] 65–85 [450–585]
70 [485] 70–90 [485–620]
1.3 The maximum thickness of plates is limited only by the
capacity of the composition to meet the specified mechanical
property requirements; however, current practice normally
limits the maximum thickness of plates furnished under this
specification as follows:
Grade U.S. [SI]
Maximum Thickness, in. [mm]
55 [380] 12 [305]
60 [415] 8 [205]
65 [450] 8 [205]
70 [485] 8 [205]
5. Heat Treatment
5.1 Plates 1.50 in. [40 mm] and under in thickness are
normally supplied in the as-rolled condition. The plates may be
ordered normalized or stress relieved, or both.
5.2 Plates over 1.50 in. [40 mm] in thickness shall be
normalized.
in. [40 mm] and under in thickness, the plates shall be
normalized unless otherwise specified by the purchaser.
Supplementary requirements
Supplementary requirements shall not apply unless specified in the purchase order.
