Naftochem OH-M70 quenching oil 200 L for steel and cast iron

Naftochem OH-M70 quenching oil 200 L for heat treatment of steel and cast iron

Naftochem OH-M70 200 L is a specialist quenching oil for hardening steel and cast iron components. The product is intended for heat treatment processes where appropriate cooling speed is required while allowing small geometrical deformation of the treated parts.

OH-M70 belongs to the Naftochem OH-M series of quenching oils. The 70 variant is designed for a lower operating temperature range than OH-M120 and OH-M160, making it suitable for processes where the recommended oil bath temperature is 40–80°C.

Application of Naftochem OH-M70 quenching oil

Naftochem OH-M70 is used for heat treatment of cast iron and steel components. The product is intended for processes requiring controlled cooling in an oil medium and repeatable hardening conditions.

It can be used in production plants, toolrooms, hardening shops, heat treatment companies and in the metalworking and machinery industries. In practice, it is suitable for steel and cast iron parts where the process allows minor geometrical deformation.

What makes Naftochem OH-M70 different

Naftochem OH-M70 quenching oil is produced from deeply refined mineral oils. It contains antioxidant and surface-active additives that increase cooling speed and help prevent deposits on the surfaces of hardened components.

For technologists and process owners, the defined viscosity range at 40°C and the recommended oil bath temperature range are important. These parameters make it easier to match the product to the process, control working conditions and avoid accidental selection of an unsuitable quenching medium.

When to choose Naftochem OH-M70 quenching oil

Choose Naftochem OH-M70 if you need an oil for hardening steel or cast iron in a process carried out at an oil bath temperature of 40–80°C. This variant is intended for applications where cooling speed, process stability and reduced deposit formation on hardened parts are important.

The 200 L packaging is suitable for companies that use larger quantities of process medium and need a capacity matched to regular industrial operation, not only to single technological trials.

What to check before use

Before use, the oil should be matched to the material type, part geometry, required cooling speed and operating temperature of the quenching bath. For Naftochem OH-M70, the recommended working temperature is 40–80°C.

If the process requires a higher operating temperature, the selection should be verified against the technological documentation and another OH-M series variant, such as OH-M120 or OH-M160, should be considered.
