Which document addresses grease in relation to NSTM?

The reference to grease in relation to the Naval Ships' Technical Manual (NSTM) is specifically covered in NSTM 262. This document focuses on the procedures and guidelines for the use of grease in various applications on naval vessels, including recommendations for appropriate types of grease, application methods, and maintenance practices. Using the correct grease is crucial for ensuring the longevity and reliability of mechanical systems aboard ships, as it impacts friction, wear, and overall system performance.

In contrast, other NSTMs mentioned focus on different topics: NSTM 208 pertains to valves and their maintenance, NSTM 150 covers the use of antifouling coatings, and NSTM 345 deals with machinery maintenance in general, none of which address grease directly. Thus, NSTM 262 is the relevant document pertaining to grease.
