ASTM A231 / A231M Abstract
This specification covers round round chromium-vanadium chromium-vanadium alloy steel spring wires having properties and quality intended for the manufacture of springs used at moderately elevated temperatures. Wires shall either be in the annealed annea led and and cold-drawn or oil-tempered condition as specified by the purchaser. The steel may either be ingot cast or strand cast, and the finished wire shall be free from detrimental pipe and undue segregation. Specimens shall undergo cast or heat heat analysis, and shall conform to required chemical compositions for carbon, manganese, phosphor p hosphorus, us, sulfur, silicon, chromium, and vanadium. Wrap tests shall also be performed wherein mechan wherein mechanical ical properties shall be assessed for tensile strength requirements. Metallurgical properties, propertie s, such as the surface condition and decarburization, shall be inspected as well. For all test procedures, one specimen shall be taken for each ten coils, or fraction thereof, in a lot. Each cast or heat in a given lot shall be tested. 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. 1. Scope
1.1 This specification covers round and shaped chromium-vanadium alloy steel spring wire having properties and quality intended for the manufacture of springs used at moderately elevated temperatures. This wire shall be either in the annealed and cold-drawn or oil-tempered condition as specified by the purchaser. 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. 1.2.1 Within the text, the inch-pound units are shown in brackets. 2.
