(Specification)Standard Specification for Pressure Vessel Plates, Carbon Steel, High-Strength Manganese
Standard Specification for Pressure Vessel Plates, Carbon Steel, High-Strength Manganese
ABSTRACT
This specification covers high-tensile strength carbon-manganese steel plates intended for welded pressure vessels. Plates are normally supplied in the as-rolled condition. The plates may be ordered normalized or stress relieved, or both. The steel shall conform to the chemical composition requirements. The plates, as represented by the tension test specimens, shall conform to the mechanical property requirements.
SCOPE
1.1 This specification covers high-tensile strength carbon-manganese steel plates intended for welded pressure vessels.
1.2 This steel is usually made to a semi-killed or capped deoxidation practice; however, at the purchaser's or the steel producer's option, the steel may be made silicon-killed or aluminum-killed.
1.3 The maximum thickness of plates furnished under this specification shall be ¾in. [20 mm].
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.
