SUPRAMANGAN is a basic coated austenitic manganese steel MMA electrode for wear resisting hard facing deposits. The weld metal will increase in hardness by cold-working, ~400-500 HB, therefore it is particularly suitable for components which are subjected mainly to wear, caused by heavy impact and shock.
During welding, the workpieces should not become too hot and if necessary should be allowed to cool down. When welding large workpieces of austenitic manganese steel, such as crusher jaw plates, it is advisable to weld in a water bath. High welding currents and wide-weave beads must be avoided. When building up several layers, it is recommended that a buffer layer is deposited with SUPERCHROMAX N. When welding austenitic manganese steel joints, e.g. 1.3401, it is preferable to use SUPERCHROMAX N. Applications include the hardfacing of wear resisting components such as crusher jaw plates, crusher cones, pulverising hammers and beating arms. One package contains approximately 135 pieces. The weight of the package is 6.5 kg.
