Tool steel working with heat. Recognized for great wear resistance, heat conductivity, hardness and robustness at increased temperatures, resistant to temperature changes. The steel is easy to work in annealed sate. Steel has better features for use due to decreased sulphur level.

Devices for preeing, cutting and forging under heat, casts for pressure casting of metals, tools for light alloy suppressing. Tools for plastic meterials processing.

Soft annealed steel, max.229 HB. For more demanding use, it is prefered to use EFS steel with guaranteed structure and sulphur content=max.0,005%
