Additives in Steel Mill Lubricants. M. S. Clark. Iron and Steel Engineer, v. 33, Oct. 1956, p. 87-93. Additives can improve many of the lubri- cants’ properties and also g&e much longer life to the lubricant. Many factors must be considered, and the use -of additive con- centrates should always be under laboratory control.
