ANSI/AGMA 6033-C08 pdf free download.American National Standard Materials for Marine Propulsion Gearing.
ANSI/AGMA 6033 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 carbunzed, 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.

4 TestIng and certification
4.1 CertIficate of test
The general tests required by AGMA 923-B05 plus the specific tests required by this standard shall be reported on a certificate of test. Each certificate of test shall report sufficient data to clearly identify the components, associated control test coupons, process and other pertinent data necessary to provide quality traceability.
4.2 Mechanical test methods
Test methods for tension, impact and hardness testing shall be in accordance with ASTM A370.
The number, location and orientation of test specimens shall be according to figure 1 and ASTM A290 or ASTM A291 as appropriate. Test bars for forged rings shall be in the tangential direction at mid-wall of the prolongation on the ring, as close as practical to the end face of the rough machined forging. Test bars for forged rings are thus actually in the longitudinal direction with respect to the direction of metal working or flow during forging or rolling. Test bars for forgings and bar stock shall be in the longitudinal or tangential direction with respect to the direction of metalworking or flow during forging unless otherwise specified.ANSI/AGMA 6033 pdf free download.
