Steel of best qualityMeusburger stands for products of fi nest quality. Steel is delivered from the most famous European steel mills and is being stress-relieved in house with great care. This unique procedure garantees our customers a low warping subsequent machining. Thanks to the temperature being maintained for a long time and slow cooling of the oven at the rate of 35°C/h we obtain the best results in terms of stress-relieved material.

In the two furnaces (Capacity 40 and 60 tons per day) the steel is being stress-relieved.

Cold-work steelCold-work steel is used for tools that are generally operated at a temperature lower than 200°C. The high alloy cold-work steel grades offer a high wear resistance combined to a good compressive strength. The low alloy grades and those having a low carbon content offer a higher toughness and suffi cient compressive strength with a reduced wear resistance.Other noteworthy features are: Economic machinability, cold formability, well polishable and suffi ciently resistant against agressive plastics.

Hot-work steelThe permanent operation temperature of hot-work steel is above 200°C. The hot-work steel thus offers best properties for tools designed to process high performance plastics. Further applications are in the fi eld of die casting, extrusion and die forging. The following properties are expected of hot-work steel: high thermal resistance and toughness, high hot-wear resistance and high thermal shock resistance.
