Description of ASTM-A229 2012

ASTM A229 / A229M - 12

Standard Specification for Steel Wire, Quenched and Tempered for Mechanical Springs

Active Standard ASTM A229 / A229M | Developed by Subcommittee: A01.03

Book of Standards Volume: 01.03




ASTM A229 / A229M

Abstract

This specification covers two classes of oil-tempered steel spring wire intended especially for the manufacture of mechanical springs and wire forms. The steel may be made by any commercially accepted steel-making process and shall either be ingot cast or strand cast. The finished wire shall be free of detrimental pipe and undue segregation. The wire shall be oil quenched and tempered to produce the desired mechanical properties such as tensile strength. Cast, heat, and product analysis shall conform to the chemical composition requirements prescribed for carbon, manganese, phosphorus, sulfur, and silicon. Tension, wrap, and surface tests shall be performed. The surface of the wire as-received shall be free of rust, excessive scale die marks, pits, and scratches detrimental to the end application. Other metallurgical requirements such as microstructure and decarburization are detailed.

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 two classes of round and shaped quenched and tempered steel spring wire intended especially for the manufacture of mechanical springs and wire forms.

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 are not necessarily exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems can result in non-conformance with the standard.


2. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard.
