ASTM International - ASTM A225/A225M-03
Standard Specification for Pressure Vessel Plates, Alloy Steel, Manganese-Vanadium-Nickel
|Publication Date:||10 September 2003|
|ICS Code (Steels for pressure purposes):||77.140.30|
1.1 This specification covers manganese-vanadium-n
1.2 Plates under this specification are available in two grades having different strength levels as follows:
|Grade||Tensile Strength,ksi [MPa]|
|3 in. [75 mm] and under Over 3 in. [75 mm]||80-105 [550-725]75-100 [515-690]|
1.3 The maximum thickness of plates is limited only by the capacity of the chemical composition to meet the specified mechanical property requirements; however, current mill practice normally limits Grade C to 0.58 in. [15 mm] maximum and Grade D to 6 in. [150 mm] maximum.
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.
