ASTM A877/A877M-16

Standard Specification for Steel Wire, Chromium-Silicon Alloys, Chrome-Silicon-Vanadium Alloy Valve Spring Quality

ABSTRACT
This specification covers the highest quality of round chromium-silicon alloy steel valve spring wires, uniform in quality and temper, intended for the manufacture of valve springs and other springs requiring high-fatigue properties when used at moderately elevated temperatures. This wire shall be either in the annealed and cold-drawn or oil-tempered condition. The steel may be made by any commercially accepted steel making process, shall be continuously cast, and shall be free from detrimental pipe and undue segregation and surface imperfections. Heat analysis, tensile testing, wrap testing, and surface inspection by magnetic or eddy current defect analysis shall be done. Both heat and product analysis shall conform to the chemical composition requirements specified for carbon, manganese, phosphorus, sulfur, silicon, and chromium. The mechanical requirements for the steel wire including cooling, heat treatment, and tensile strength, and the metallurgical requirements including etched surface testing, decarburization, and inclusion content are detailed.
SCOPE
1.1 This specification covers the highest quality of round and shaped chromium-silicon and chromium-silicon-vanadium alloys of steel valve spring wire, uniform in quality and temper, intended for the manufacture of valve springs and other springs requiring high-fatigue properties when used at moderately elevated temperatures. It is similar to the grade VD (referenced in EN 10270-2) intended for high fatigue levels. This wire shall be either in the annealed and cold-drawn or quenched and tempered condition as specified by 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.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
