    Abstract

    This specification deals with carbon and alloy steel forgings (including gas bottles) for use in thin-walled pressure vessels. Covered here are the following grades of steel forgings: Grade A; Grade B; Grade C; Grade D; Grade E, Classes 55, 65, and 70; Grade F, Classes 55, 65, and 70; Grade G, Classes 55, 65, and 70; Grade H, Classes 55, 65, and 70; Grade J, Classes 55, 65, and 70; Grade K; Grade L; Grade J, Class 110; and Grade M, Classes 85 and 100. Materials shall be manufactured by melting procedures, and optionally heat treated by normalization, normalization and tempering, or liquid-quenching and tempering. Heat and product analyses shall be performed wherein steel specimens shall conform to required chemical compositions of carbon, manganese, phosphorus, sulfur, silicon, nickel, chromium, molybdenum, and vanadium. Steel materials shall also undergo bending, flattening and hardness tests and shall conform to required values of tensile strength, yield strength, elongation, and hardness. Forgings shall be subjected to magnetic particle examination as well.

    This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

    Significance and Use

    1. Scope

    1.1 This specification covers homogeneous wrought hardened alloy steel rolls for use in cold or hot reduction of flat rolled ferrous and nonferrous products.

    1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values 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-conformance with the standard.

    1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
