Abstract
Abstract Metal working lubricating compositions useful as a precoating oil and as a coating and rolling operation, comprising mineral or synthetic oil and a sulfur containing carboxylic acid such as n-dodecylthioacetic acid and n-butylthioacetic acid. The composition can also contain vegetable oil or animal fat. The lubricant composition provided is particularly useful in the cold rolling of steel and other metals.

Claim 1
Independent Claim
74 words
A lubricant composition for metal fabrication comprising a major proportion of a mineral or synthetic oil having incorporated therein (1) from 0.1 to about 10 percent by weight of the finished composition of at least one alkylthiohydrocarbylcarboxylic acid and (2) from 1-6 weight percent of a vegetable oil or animal fat sufficient to improve extreme pressure properties of the oil and to reduce wear and improve surface appearance of parts in highly loaded contact.
Claim 2
Dependent Claim
74 words
A lubricant composition for metal fabrication comprising a major proportion of a mineral or synthetic oil having incorporated therein (1) from 0.1 to about 10 percent by weight of the finished composition of at least one alkylthiohydrocarbylcarboxylic acid and (2) from 1-6 weight percent of a vegetable oil or animal fat sufficient to improve extreme pressure properties of the oil and to reduce wear and improve surface appearance of parts in highly loaded contact.
