SOZh MR-1U is made from a scavenge oil base blended with antiwear, extreme-pressure and anticorrosive additives.

SOZh MR-1U is used in the process of machine and automated cutting, including some thread cutting operations (with a screw-cutter, threading die or a milling cutter), drawing, gear shaping and drilling of carbon and alloy-treated structural stainless steels.

It is mostly used in machine building.
