Hardox 500 Plattenware 1000mmx2000mm

hot forming The steel is up to no additional heat treatment 250 ° C hot forming. Machining Drilling with high speed steels HSSCO. Milling with HM tools with negative rake angle. Lubrication with emulsion. The cutting parameters should be adapted to the material properties. Separate Water jet, plasma and laser cutting are recommended due to the low heat input at the cutting edges, flame cutting is also possible. For thermal separation processes, a material temperature should be of 15 ° C are not fallen below. For sheet thicknesses greater than 15 mm should be preheated to at least 100 ° C. welding The steel is basically suitable for all known welding processes. The material temperature should be at least 15 ° C during welding. In addition, it is recommended to observe As the welding process, the combined sheet thickness, the residual stress state of the structure, the energy per unit length and the hydrogen content of the weld metal, preheat. The necessary preheating and interpass temperatures arise in accordance with the corresponding Rules such. SEW 088 and EN 1011-2. The preheating and interpass temperatures should not exceed 250 ° C, the above parameters should be adjusted accordingly. The residual stress state of the construction should be optimized by a suitable welding sequence. Special care is necessary regarding hydrogen uptake. The environment of the weld should therefore be free from dirt and moisture. To reduce the danger of cold cracking, a direct subsequent reheating from the welding heat over 2 h at 250 ° C is recommended. Welding consumables There are generally welding consumables of the desired strength class, which form a deformable, tough weld metal, z. B. basic coated electrodes to choose. The materials should have the lowest possible hydrogen content, the drying and processing instructions of the respective manufacturer must be observed. When the wear of the seam is wear-resistant, the appropriate area must be built up with suitable additives. additional This grade was developed with the aim of reducing CO2 emissions during production. The goal is achieved by saving heat treatment steps while increasing application performan
