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:

GradeTensile Strength,
ksi [MPa]
Type
A7595 [515655] manganese-molybdenum
B80100 [550690]manganese-molybdenum
C80100 [550690]manganese-molybdenum-nickel
D80100 [550690]manganese-molybdenum-nickel

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.


This specification covers manganese-molybdenum and manganese-molybdenum-nickel alloy steel plates intended particularly for welded boilers and other pressure vessels. According to their strength levels, the plates are available in four grades: Grades A, B, C, and D. The maximum thickness of plates is limited only by the capacity of the chemical composition to meet the specified mechanical property requirements. The steel shall be killed and shall conform to fine grain size requirements. The plates shall be subjected to tension test to determine the tensile strength, yield strength, and elongation.
