Thick basic-covered electrode for producing hard facing deposits of medium hardness, which can be machined by chip-forming. 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 pssible to use also in AC.

Basic covered, austenitic manganese steel electrode for wear resisting hardfacing deposits. 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 EIS 307 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.

Thick basic-covered electrode for producing highly wear resisting hard facing deposits. It is particularly resistant to metal-to-metal wear, impact and shock. Weld metal can be machined only by using sintered hard metal tipped tools. A tough buffer layer using ESB 40 or EI 307 electrodes is solely required in case of very crack sensitive base metal. Even a large number of layers can be deposited without the need of intermediate buffer layers. EH 340 can be welded in all positions, except vertical-down. 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. Preferred to use with DC, electrode in positive (+) pole and also possible to use with AC.

Thick rutile-covered electrode for depositing tough and wear resisting hardfacing overlays. The weld metal has sufficient red hardness up to 600°C. It is machinable only by grinding. In case of crack sensitive base metals, a tough buffer layer made by ESB 40 or EI 307 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. Suitable hardfacing applications where wear resistance at higher temperatures is a prime concern, as in hot cut offs, dies for pressure castings, rolls, crushers and others. Possible to use equally well both with AC and DC.

Thick basic-covered electrode for depositing tough and wear resisting overlays on structural members subjected to severe wear. The weld metal is free of cracks and pores and resistant to impact and shock. It can be machined only by grinding. Only in case of very crack sensitive base metals, a tough buffer layer, made with ESB 40 or EI 307 B electrodes, is required. Multi-layers deposits will be free of cracks, even without depositing intermediate buffer layers. Suitable for hardfacing excavator parts, bucket edges and bucket teeth, drilling bits, coal planes, conveyor screws, polygon edges, crusher jaws and cones. Preferred to use with DC, electrode in positive (+) pole and also possible to use with AC.

Hardfacing electrode for manufacturing and repair welding of turning and plaining chisels, reaming blades, special spiral drills. Also suitable for manufacturing tools from unalloyed and low alloy steels and hardfacing the edges of cutting tools made of tool steel. Unalloyed and low alloy steels shall be preheated to 250°C - 400°C before welding and postweld heat treatment at 400°C and then welded parts shall be cooled slowly. If buffer layer is needed, can be performed by EI 312 or EI 307 electrodes (max. 2.5 mm) and then hardfacing can be performed by EH 380 (max. 5 mm in heigth). Possible to use with DC, electrode in positive (+) pole and with AC.

Thick rutile-covered high-alloy electrode depositing hypereutectic chromium hard metal. It is suitable for producing highly wear resisting deposits subject to abrasion by mineral particles. The typical transverse cracks appearing in this hardfacing weld metal are not detrimental to abrasion resistance. However, the weld metal is not resistant to impact and shock, and is machinable only by grinding. On difficult-to-weld steels, a buffer layer made with EI 307 B electrodes is required. EH 515 produces very smooth weld beads with flat penetration. Metal recovery is approx. 160 %. Suitable for hardfacing wearing parts subject to mineral abrasion, such as, conveyor screws, mixer blades, concrete pump parts, slurry pumps, stirring and agitator parts, crusher parts, excavator bucket edges, coal planes subject to corrosion at elevated temperatures. Possible to use both with AC and DC.
