TU 0258-002-76665089-05
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.
