Plastic Mould 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 (SuperClean™).

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.

Bohler steel

For the manufacture of plastic parts, steels are required which have a high wear resistance and good polishability, which can be easily machined, grained have adequate corrosion resistance. Depending on the properties required, case-hardening steels, heat treatable steels, corrosion resistant steels, nitriding steels and martensite hardening steels or high performance powder metallurgical materials are used. The quality of Bohler steels is second to none and fills all of the above requirements.

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.
