E 7-UM-200-KP

Basic covered, austenitic manganese steel electrode for wear resisting hardfacing deposits on high manganese (12-14%) steels. Weld metal will adopt high hardness by cold-working, it is therefore particularly suited for parts which are subjected mainly to wear caused by heavy impact and shock. During welding, the workpieces should not become too hot and if necessary, be allowed to cool down. When welding large workpieces made of austenitic manganese steel, such as crusher jaw plates, it is advisable to weld them in a water bath. High welding currents and wide-weave beads must be avoided. When building up various layers, it is good practice depositing a buffer layer with EI 307 weld metal. When making joint welds on austenitic manganese steel, it is preferable to use EI 307B electrodes. Suitable for hardfacing and repair welding of wear resisting parts made of austenitic manganese steel, such as crusher jaw plates, crusher cones, rolls, pulverizing hammers, beating arms and others. Preferably used with DC, electrode in positive (+) pole and also possible to use with AC.

Particularly suited for wear resisting parts subjected to metal-to-metal wear, heavy impact and shock. EH 330 can be easily welded in all positions, except vertical-down. Weld metal is crack resistant and free of pores. suitable for reconditioning of rails, rail crossings, switch points, sprockets and wearing parts, such as rope pulleys, tumblers, rollers, caterpillar track rollers and links, wheel flanges, stud links and others. DC, electrode in positive (+) is preferred and possible to use also in AC.

E 1-UM-400

Thick basic-covered electrode for producing highly wear resisting hardfacing deposits. It is particularly resistant to metal-to-metal wear, impact and shock. Suitable for reconditioning of rails, rail crossings and switch points, wearing parts such as dredger parts, polygon edges, bearing surfaces, striking tools, die tyres, wheel flanges, slide surfaces subject to heavy wear, reconditioning of lower dies, punches and others.Weld metal can be machined only by using sintered hard metal tipped tools. Even a large number of layers can be deposited without the need of intermediate buffer layers. A tough buffer layer using ESB 40 or EI 307B electrodes is solely required in case of very crack sensitive base metal. EH 340 can be welded in all positions, except vertical-down. Preferred to use with DC, electrode in positive (+) pole and also possible to use with AC.

E 6 UM 60 T

Thick rutile-covered electrode for depositing tough and wear resisting hardfacing overlays. It is particularly resistant to high meta-to-metal wear, moderate impact and abrasion. The weld metal has sufficient red hardness up to +600°C. It is machinable only by grinding. Suitable hardfacing applications where wear resistance at higher temperatures is a prime concern, as in hot cut offs, dies for pressure castings, rolls, crushers excavator parts, bucket edges and bucket teeth, drilling bits, coal planes, conveyor screws. In case of crack sensitive base metals, a tough buffer layer made by ESB 40 or EI 307B electrodes, is required and a further one after every third hardfacing layer. The as-welded hardness of 59 HRc can be increased to 60-65 HRc by single or double tempering. Possible to use equally well both with AC and DC.

E 6 UM 60 T

Thick basic-covered electrode for depositing tough and wear resisting overlays on structural members subjected to severe wear. It is particularly resistant to high meta-to-metal wear, moderate impact and abrasion. The weld metal has sufficient red hardness up to +600°C. It can be machined only by grinding. Suitable hardfacing applications where wear resistance at higher temperatures is a prime concern, as in hot cut offs, dies for pressure castings, rolls, crushers excavator parts, bucket edges and bucket teeth, drilling bits, coal planes, conveyor screws. Multi-layers deposits will be free of cracks, even without depositing intermediate buffer layers. Only in case of very crack sensitive base metals, a tough buffer layer, made with ESB 40 or EI 307B electrodes, is required. Preferred to use with DC, electrode in positive (+) pole and also possible to use with AC.
