Medium alloyed tool steel for cold work, great robustness and heat resistance, high strength in hot environments, high robustness inhot environments and low dimensional during heat processing. Steel has for use due to decreased sulphur level.

Devices for forming and cutting of metals under heat.
Casts for pessure casting of non-ferrous metals.

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%
