ASTM A203/A203M-97(2003)

Standard Specification for Pressure Vessel Plates, Alloy Steel, Nickel

SCOPE
1.1 This specification covers nickel-alloy steel plates intended primarily for welded pressure vessels.
1.2 Plates under this specification are available with four strength levels and two nickel compositions as follows: NominalYieldTensile NickelStrength,Strength, Contentmin, ksimin, ksiGrade%[MPa][MPa] A2.2537 [255]65 [450] B2.2540 [275]70 [485] D3.5037 [255]65 [450] E3.5040 [275]70 [485] F3.502 in. [50 mm] and under 55 [380]80 [550] Over 2 in. [50 mm] 50 [345]75 [515]
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:  GradeMaximum Thickness,in. [mm]A6 [150]B6 [150]D4 [100]E4 [100]F4 [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.
