1.1 This specification covers manganese-molybdenum and manganese-molybdenum-nickel alloy steel plates intended particularly for welded boilers and other pressure vessels.
1.2 Plates under this specification are available in four grades having different strength levels as follows:
| Grade | Tensile Strength, ksi [MPa] | Type |
| A | 75-95 [515-655] | Mn-Mo |
| B | 80-100 [550-690] | Mn-Mo |
| C | 80-100 [550-690] | Mn-Mo-Ni |
| D | 80-100 [550-690] | Mn-Mo-Ni |
1.3 The maximum thickness of plates is limited only by the capacity of the chemical composition to meet the specified mechanical property requirements. The minimum thickness is limited to 0.25 in. [6.5 mm].
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. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Combining values from the two systems may result in nonconformance with the specification.
