Materials for Marine Propulsion Gearing
|Publication Date:||29 September 2008|
This standard identifies commonly used alloy steels, heat treatments and inspection requirements for through hardened and surface hardened gearing for main propulsion marine service over 1500 hp. Forged and hot rolled alloy steel bar stock are specified to two metallurgical quality grades (1 and 2) according to cleanliness and test requirements. Cast steel gearing is specified to a single metallurgical quality level. Mechanical, metallurgical and nondestructive test requirements are provided for various heat treatment processes and metallurgical quality grades of gearing. Revision of ANSI/AGMA 6033-B98.
