Low-viscosity cold rolling oil for ferrous and non-ferrous metals
Business customers only. We sell wholesale, invoiced to registered companies.

Somentor AH 45 is the lowest-viscosity grade of the ExxonMobil Somentor A Series of premium, fully compounded cold rolling oils, with a kinematic viscosity of 4.2 mm²/s at 40°C, a flash point of 140°C and a pour point of -6°C. It is formulated with high quality base stocks and specially selected roll oil additives for the cold rolling of ferrous and non-ferrous metals, including high carbon, austenitic and ferritic stainless steel as well as copper and copper alloys. Like the rest of the series, it suits all mill configurations, from 4-hi through to 20-hi multi-roll mills, can lubricate back-up bearings in multi-hi mills, and is compatible with filter systems using active and/or inactive earth filter media. It can also be used in rolling mill hydraulic systems, depending on pump suitability for low-viscosity oils. Its low viscosity improves cooling efficiency, and it can be blended with AH 70 and AL 70 to cost-effectively adjust their viscosity. Key benefits include a bright surface finish on rolled metal, clean evaporation during annealing that avoids residues and deposits, and easy filtration for extended oil life.
