Best practice in heat treatment of large dies made of hot work tool steels
Tool steels are a widely used material for construction of tools designated for shaping and forming of metal, plastic and other elements in mass production. These elements include extruding dies, pressure casting dies, moulds, punches and various other elements for plastic shaping of other materials preheated to temperatures in the range of 250-700 °C (Fig. 1). Since shape stability constitutes...
متن کاملEVALUATION OF THE MECHANICAL PROPERTIES OF NIOBIUM MODIFIED CAST AISI H 13 HOT WORK TOOL STEEL
Abstract: mechanical properties of AISIH 13 hot-work tool steel have been studied. Cast samples made of the modified new steel were homogenized and austenitized at different conditions, followed by tempering at the specified temperature ranges. Hardness, red hardness, three point bending test and Charpy impact test were carried out to evaluate the mechanical properties together with characteriz...
متن کاملLaser Grooving of Surface Cracks on Hot Work Tool Steel
Repair welding (RW) with wire cladding is a common procedure to extend the in-service life of heavily loaded tool parts for die and mould industries 1-5 . The main advantages of repair welding are short downtime and cost efficiency compared to production of new tool part. Repair welding in general lowers the tool cost in the final part and enables higher added value to the die casting and injec...
متن کاملThe structure-property relationship in a desulfurised and degassing hot work W500 tool steel
The effect of secondary steelmaking processes such as desulphurization, removal of inclusions and vacuum degassing followed by hot forging and hardening heat treatment on the microstructure and mechanical properties of a hot-work w500 tool steel have been studied in details. In order to follow the progress of secondary steel making, the content of impurity elements such as S, P, O, H and N were...
متن کاملSolidification Phenomena and Properties of Some Cast Tool Steels
The freezing process. microstructures and phase relationships in some experimental cast tool steels have been investigated and developed under the various solidification conditions. Experimental steels were based on AISI M2 and M10 grades high speed steels. Addition of carbide forming elements such as niobium and titanium with and without extra carbon were made to the molten bath of the base st...
