Description

SCOPE

This standard is applicable to marine gearing made from steel forgings, bar stock and castings intended for main propulsion service over 1500 horsepower. Alloy steel specifications and quality assurance measures presented represent the state of the art and are not intended to assure the performance of subject assembled marine gear drive systems.

This standard pertains to through hardened gearing, as well as carburized, nitrided and induction contour surface hardened gear teeth of pinions and gears. This standard presents the properties of commonly available alloy steels used for marine gearing. It is recognized that modifications of these alloys and other suitable alloy steels are available which may be used in marine gearing. It does not address other forms of surface hardening, such as flame hardening and spin coil induction hardening.

Requirements for Quality Grades 1 and 2 are defined in this standard. Although reference is made to Grade 3 melting practice for carburized steels, the experience with the use of these steels is limited and therefore outside the scope of this standard.

This standard is intended for use by those experienced in gear design or manufacture. It is not intended for use by the engineering public at large.

FOREWORD

[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 6033-C08, Materials for Marine Propulsion Gearing.]

The purpose of ANSI/AGMA 6033-C08 is to provide alloy steel specifications and quality assurance measures for pinions and gears used in main propulsion marine applications.

This document consolidates and adapts the material specifications generally used for pinions and gears in the defined marine propulsion applications.

ANSI/AGMA 6033-A88 was proposed to the Technical Division Executive Committee in 1979 by the Chairman of the Marine Gearing Committee. Interest in, and the need for this standard was expressed at a committee meeting in February 1980. Work began on rolled ring forgings for rims of large fabricated gears. Metallurgists from several member companies attended that and subsequent meetings. The committee continued work on the standard, expanding the contents to include other forms of gearing, properties of commonly available alloy steels, heat treatment methods and inspection requirements.

The Marine Gearing Committee submitted the standard, and it was approved by the entire AGMA membership in its final edited version in March 1988. On May 31, 1988 it was approved as an American National Standard.

In late 1993 the AGMA Technical Division Executive Committee recommended that the Marine Gearing Committee review and update ANSI/AGMA 6033-A88, Standard for Marine Propulsion Gear Units, Part 1, Materials. This review and update was initiated in early 1994. ANSI/AGMA 6033-B98 was renamed Materials for Marine Propulsion Gearing.

ANSI/AGMA 6033-B98 was approved by the membership in July, 1997 and approved as an American National Standard on June 19, 1998.

ANSI/AGMA 6033-C08 is a revision of ANSI/AGMA 6033-B98 to reflect metallurgy and materials practices currently in use in marine applications, and to refer to other recent AGMA publications.

AGMA Standards are subject to constant improvement, revision, or withdrawal as dictated by experience. Any person who refers to an AGMA technical publications should be sure that the publication is the latest available from the Association on the subject matter.

The first draft of ANSI/AGMA 6033-C08 was made in January 2003. It was approved by the AGMA membership in July, 2008. It was approved as an American National Standard on September 29, 2008.
