Hot Work Tool Steels

Hot work tool steels are specialized alloys designed to withstand extreme conditions during the hot-forming of metallic workpieces. These steels facilitate manufacturing processes such as pressure die casting, extrusion, and drop forging at elevated temperatures. Distinguished by their ability to maintain hardness and structural integrity despite thermal cycling, hot work tool steels require specific properties including high tempering resistance, thermal shock resistance, and wear resistance.

Iron Spark Plasma Sintering (SPS): Part One

Spark Plasma Sintering (SPS) is a sintering technique which is well matched to mechanically milled materials such as tool steels due to its low temperature and short cycle time.
Tool steels have been specifically manufactured to exhibit exceptionally high strain hardening, a characteristic which can be undone by high temperature sintering processes such as hot isostatic pressing.

Iron Spark Plasma Sintering (SPS): Part Two

Spark Plasma Sintering (SPS) is a sintering technique which is well matched to mechanically milled materials such as tool steels due to its low temperature and short cycle time.
One of the key objectives using SPS is to increase the density of the sinter in order to attain better overall property profiles of the finished part.

Maraging Tool Steels

Superior properties, such as high ductility, high yield stress, good hardenability, good weldability, simple heat treatment without deformations, have led to a widespread application of maraging steels, not only in the manufacturing of diverse construction components, but also in the manufacturing of molds, i.e. for processing of polymers, for pressure casting, etc.

Plastic Mold Steels

Continuously growing activity in the area of the engineering plastics led to the necessity of developing new low-cost, high-performance plastic mold steels.
Precipitation hardening tool steels are being proposed for such an application, yielding improved mechanical properties and lower overall costs and lead-times.

Polish (PN/H) Standards for Steel Materials

This group of PN standard specifications covers carbon and alloy steels, plates and forgings used in boilers and pressure vessels, high-strength low-alloy steels, heat-treatable steels, sheets and strips. This article contains standards for various types of steel pipes which specify requirements for high-temperature service, and special applications such as fire protection use. Steel casting and high temperature cast steel specifications call out the standard properties for pressure purposes. The group of standards for tool steels, stainless and heat resisting steels is also presented.
