(Specification)Standard Specification for Pressure Vessel Plates, Carbon-Manganese-Silicon Steel, for Moderate and Lower Temperature Service
Standard Specification for Pressure Vessel Plates, Carbon-Manganese-Silicon Steel, for Moderate and Lower Temperature Service
ABSTRACT
This specification covers three grades, Grades A, B, and C, of carbon-manganese-silicon steel plates intended primarily for service in welded pressure vessels where improved low temperature notch toughness is important. The maximum thickness of plates is limited only by the capacity of the composition to meet the specified mechanical property requirements. The steel shall be killed and the plates shall undergo heat treatment. Tensile properties such as tensile strength, yield strength and elongation shall be determined by subjecting the steel plates to a tension test.
SCOPE
1.1 This specification covers three grades of carbon-manganese-silicon steel plates intended primarily for service in welded pressure vessels where improved low temperature notch toughness is important.
1.2 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 to 2 in. [50 mm].
1.3 Grades A, B, and C comply substantially with the requirements of ISO Pressure Vessel Steels P9, P15, and P18, respectively.
1.4 For plates produced from coil and furnished without heat treatment or with stress relieving only, the additional requirements, including additional testing requirements and the reporting of additional test results, of Specification A 20/A 20M 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.

3.5Coiled product is excluded from qualification to this specification until it is decoiled, leveled, and cut to length. Plate
produced from coil means plate that has been cut to individual lengths from a coiled product and is furnished without heat
treatment. The processor decoils, levels, cuts to length, and marks the product. Except as allowed by Section 6 in Specification
A20/A20M, the processor is responsible for performing and certifying all tests, examinations, repairs, inspections, and operations
not intended to affect the properties of the material. For plate produced from coils, the results of the tests performed shall be
reported for each qualifying coil. See Note 1. General Requirements and Ordering Information
