ASTM A285/A285M-90(2001)
(Specification)Standard Specification for Pressure Vessel Plates, Carbon Steel, Low- and Intermediate-Tensile Strength
Standard Specification for Pressure Vessel Plates, Carbon Steel, Low- and Intermediate-Tensile Strength
SCOPE
1.1 This specification covers carbon steel plates of low- and intermediate-tensile strengths which may be made by killed, semi-killed, capped, or rimmed steel practices at the producer's option. These plates are intended for fusion-welded pressure vessels.
1.2 Plates under this specification are available in three grades having different strength levels as follows:Tensile Strength,Gradeksi [MPa]A45-65 [310-450]B50-70 [345-485]C55-75 [380-515]
1.3 The maximum thickness of plates under this specification, for reasons of internal soundness, is limited to a maximum thickness of 2 in. [50 mm] for all grades.
Note 1—For killed carbon steels only refer to the following ASTM specifications:A299/A299M Pressure Vessel Plates, Carbon Steel, Manganese-Silicon.
A515/A515M Pressure Vessel Plates, Carbon Steel, for Intermediate- and Higher-Temperature Service.
A516/A 516M Pressure Vessel Plates, Carbon Steel, for Moderate- and Lower-Temperature Service.
1.4 For plates produced from coil, the additional requirements, including additional testing requirements and the reporting of additional test results, of Specification A20/A20M apply.
1.5 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.
