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 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 کاملEffect of Cryogenic Treatment on Mechanical Properties of Cold Work Tool Steels
In this paper effect of cryogenic treatment on mechanical properties of cold work tool steels at various combination of heat treatment cycle (process sequence) are studied. The material selected for these processes are AISI D2 and D3.Cryogenic treatment is commonly referred as cryotreatment, is an add-on process to the conventional heat treatment of tool steel. Cryogenic treatment improves hard...
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 کاملExperimental Investigations on Heat Treatment of Cold Work Tool Steels: Part 1, Air-hardening Grade (d2)
The present experimental investigations deal with the improvement of mechanical properties of cold work tool steels through different heat treatment processes. An attempt was made to get optimal combination of hardness and toughness through changes of microstructure by heat treatment. The toughness of D2 tool steel increases with tempering temperature. The hardness of D2 tool steel decreases wi...
