This specification covers a group of common requirements that apply to rolled steel plates for pressure vessels. The steel shall be made in an open-hearth, basic-oxygen, or electric-arc furnace process. Sampling and methods for chemical analysis are discussed. Yield strength tests, tension tests, and notch-toughness tests shall be made in accordance to the product specification to conform to the specified requirements.

1.1.1 This general requirements specification alsocovers a group of supplementary requirements that are applicable toseveral of the above product specifications as indicated therein.Such requirements are provided for use if additional testing oradditional restrictions are required by the purchaser, and applyonly if specified individually in the purchase order.

1.2 Appendix X1 provides information on coil as asource of plates for pressure vessels.

1.3 Appendix X2 provides information on thevariability of tensile properties in plates for pressurevessels.

1.4 Appendix X3 provides information on thevariability of Charpy-V-Notch impact test properties in plates forpressure vessels.

1.5 Appendix X4 provides information on cold bendingof plates, including suggested minimum inside radii for coldbending.

1.6 These materials are intended to be suitable forfusion welding. When the steel is to be welded, it is presupposedthat a welding procedure suitable for the grade of steel andintended use or service will be utilized.

1.7 In case of any conflict in requirements, therequirements of the applicable product specification prevail overthose of this general requirements specification.

1.8 Additional requirements that are specified inthe purchase order and accepted by the supplier are permitted,provided that such requirements do not negate any of therequirements of this general requirements specification or theapplicable product specification.

1.9 For purposes of determining conformance withthis general requirements specification and the applicable productspecification, values are to be rounded to the nearest unit in theright-hand place of figures used in expressing the limiting valuesin accordance with the rounding method of Practice E29.

1.10 The values stated in either SI units orinch-pound units are to be regarded separately as standard. Thevalues stated in each system may not be exact equivalents;therefore, each system shall be used independently of the other.Combining values from the two systems may result in non-conformancewith the standard.

1.11 This general requirements specification and theapplicable product specification are expressed in both inch-poundunits and SI units; unless the order specifies the applicable “M”specification designation (SI units), the plates are to befurnished to inch-pound units.
