Standard Specification for Pressure Vessel Plates, Heat-Treated, Carbon-Manganese-Silicon Steel
1.1 This specification2 covers heat-treated carbon-manganese-silicon steel plates intended for fusion welded pressure vessels and structures.
1.2 Plates furnished under this specification are available in the following three classes:
1.3 The maximum thickness of plates is limited only by the capacity of the material to meet the specified mechanical property requirements.
1.4 The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets.
