HOT ROLLING OIL COMPOSITION FOR STAINLESS STEEL

摘要

PROBLEM TO BE SOLVED: To obtain a hot rolling oil composition having high baking resistance, capable of applying to hot rolling of stainless steel for which high baking resistance is required. SOLUTION: This composition is obtained by adding 40-90 wt.% sulfide ester having >=10 wt.% sulfur content or mixture of the sulfide ester with a polysulfide having >=20 wt.% sulfur content to one or more kinds of base oils among a mineral oil, oil and fat and a synthetic ester. The composition is used as a hot rolling oil for stainless steel.
