Scope

1.1 This specification covers molybdenum-alloy steel plates, intended particularly for welded boilers and other pressure vessels.

1.2 Material under this specification is available in three grades having different strength levels as follows:

Tensile Strength, Grade ksi [MPa] A 65-85 [450-585] B 70-90 [485-620] C 75-95 [515-655]

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:

Maximum Thickness, Grade in. [mm] A 6 [150] B 6 [150] C 4 [100]

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 this specification.
