Cold Work


Cold Work Tool Steels are used for cutting and pressing tools, for dies and knives, for stamping and drawing tools, hobs, thread rolling tools and in many other applications due to their typical properties – high hardness, good toughness and compressive strength and high wear resistance. Availability, cost efficiency and a long tool life are the most important factors in choosing a material.

ESR

Electro Slag Remelted In Electro Slag Remelting the ingot is built up in a water cooled mould by melting a consumable electrode immersed in a superheated process slag. An electrical current flowing through the liquid slag, which provides the electrical resistance, generates the heat. As the slag temperature rises above the liquids temperature of the steel, the tip of the electrode melts. The reaction between slag and steel droplets results in a significant reduction in sulphur and non-metallic inclusions. The directional solidification of the ingot from bottom to top results in an ingot with a high homogeneity and freedom from macro - segregations. This gives uniform mechanical properties in the longitudinal and transverse directions after hot working. By utilizing homogenisation annealing of ingots, a high ingot break down and special heat treatment methods for structure refinement and strategy is fulfilled in optimising steel properties for an extended tool life.

Powder Metallurgy Grades

Process for PM tool steel     High Alloy Steels will gain improved properties by increasing the solidification rate. This gives a fine microstructure and small, well-distributed carbides in the matrix.

During Powder Metallurgy (PM), the melt stream is atomised by nitrogen gas into small droplets with an average size of 50-100 µm. The powder is filled into capsules directly in order to avoid contamination. With hot isostatic pressing (HIP), the powder is consolidated to 100% density.

By using a special refining sequence, the cleanliness of the molten steel is improved prior to atomisation. This results in improved mechanical properties and an extremely low non-metallic inclusion level (Super Clean™).

The HIP'ed PM capsules are hot forged and rolled to smaller bar sizes followed by heat treatment and machining.

PM steels are used in very demanding applications within cold work, plastic and cutting tools.
