This manual was developed to provide basic information and recommend sources of additional information pertaining to metallic gear materials, their treatments, and other considerations related to the manufacture and use of gearing.
The gearing application conditions, including allowable stresses, environment, component geometry, and component weight limitations, must be understood to select the proper gear material.
Metallurgical aspects of gearing as related to rating (allowable contact stress number and allowable bending stress number) are not included, but are covered in AGMA rating standards.
[The foreword, footnotes and annexes, if any, in this document are provided for informational purposes only and are not to be construed as a part of AGMA Standard 2004-C08, Gear Materials, Heat Treatment and Processing Manual.]
ANSI/AGMA 2004-C08 provides a broad range of information on gear materials, gear heat treatment, and associated processing. This information is intended to assist the designer, the process and manufacturing engineer, and the heat treater to effectively produce the gearing required for the application. Data contained herein represents a consensus from metallurgical representatives of member companies of AGMA.
The goal of ANSI/AGMA 2004-C08 is to present information in a sequence that can be used to make the necessary technical decisions when producing gearing. ANSI/AGMA 2004-C08 includes updated and extensively revised information from ANSI/AGMA 2004-B89 along with additional information needed to achieve this goal.
ANSI/AGMA 2004-B89 superseded AGMA 240.01, Gear Materials Manual, October 1972, because of a Metallurgy and Materials Committee decision to revise the document format. On January 23, 1989, ANSI/AGMA 2004-B89 was approved as an American National Standard.
This standard has been updated to reflect current technology in the area of steel making and heat treatment, and edited to include cross references to relevant AGMA standards and information sheets.
The first draft of AGMA 2004-C08 was completed in May 2001. It was approved by the AGMA membership in October, 2007. It was approved as an American National Standard on January 8, 2008.
Suggestions for improvement of this standard will be welcome. They should be sent to the American Gear Manufacturers Association, 500 Montgomery Street, Suite 350, Alexandria, Virginia 22314.
