General Information

It is an alloy tool steel group that provides the shaping of ferrous and non-ferrous materials under high temperature conditions (300-600 ° C) by various methods such as injection, extrusion, forging, cutting. Hot work tool steels used in the process of shaping metal-based raw materials at high temperatures are the steel group that has a considerable usage area in today's manufacturing and mold industry. It has a wide range of applications from various household appliances to the construction industry, from machinery manufacturing to the automotive supplier industry. The main criteria to be considered in the optimal selection of BUDERUS Hot Work Tool Steels used for forging, extrusion and injection molds are; The mold usage conditions are the geometry of the product to be produced, the cross-section distribution depending on the part weight and the most important is the mold life depending on the number of parts to be produced. 1.2343 ISO-B mod, 1.2344 ISO-B, 1.2365 ISO-B, 1.2367 ISO-B and 1.2714ISO-B mod quality hot work tool steels are the prominent materials in terms of usage. The heat treatment of 1.2714 pre-hardened (40-44 HRc) hot work steels, which are widely used especially in hot steel forging processes, is carried out successfully by suitable controlled furnaces and other heat treatment facilities and equipment specific to block sizes. In line with the process to be applied in steel forging dies, the right steel selection (for example, if the presses are Hammer or Friction) and the availability of high quality steel alternatives are other important issues to increase the mold life and efficiency. In particular, the maintenance and treatment of the surface and engravings are important in terms of mold efficiency and process costs, which prevent deterioration or other possible damage during the process. Especially in aluminum extrusion dies, 1.2344, 1.2343 and 1.2714 grades can be used in the support parts of these mold systems.

In Mold Cores of Metal Injection Molding (Especially Aluminum); 1.2340-Esu, 1.2343-Esu and 1.2344-ESR Grades are recommended for mold life or high print quantities. Esu quality hot work steels; Due to its homogeneous structure with high purity in terms of impurity, its defects have been eliminated due to its internal structure, and it gives successful results for mold applications where high printing numbers are desired.

Uses of Hot Work Tool Steels

• In molds where forging, casting, injection and extrusion processes of metal materials are carried out,

• Mold Core, cores and thrusters of metal injection molds, especially aluminum.

• In pressure casting molds of light and heavy metals, mold and pipe presses, internal intermediate sleeves, piercing punches and mandrels,

•  In hot cutting and deburring tools,

• Under welded reels in welded pipe production,

•  It is used in Plastic Injection Mold applications where High Cycle Number, High surface quality and wear resistance are required.
