S757 ESpecial Electrodes for Alloy Steel
NiCr15Fe6Mn Crack-Resistant Alloy Steel Electrode
Covered Electrode
A crack-resistant NiCr15Fe6Mn alloy steel electrode used for the maintenance and repair of various metals such as nickel alloys (Inconel and Incoloy), alloy steel, and stainless steel. Also used to repair cracks and join thick steel sections. This electrode's mechanical properties are unaffected by heat treatment. Resistant to extreme temperatures (200°C-1000°C), heat, oxidation, and corrosion. Suitable for the cement, chemical, and oil & gas industries.
S737 ESpecial Electrodes for Alloy Steel
Ferritic-Austenitic CrNi Special Steel Electrode
Covered Electrode
A special ferritic-austenitic CrNi alloy steel electrode with added value for repairing and maintaining a wide range of different steels, such as carbon steel, tool steel, high speed steel, low- and high-alloy steels, manganese steel, cast steel, rail steel, cast iron, and all types of stainless steel. Used to repair gears, casings, shafts, and steel of unknown chemical composition. Heat resistant to 1000°C.
S727 ESpecial Electrodes for Alloy Steel
CrNi Special Steel Electrode for Thick & High-Alloy Steel
Covered Electrode
A special CrNi alloy steel electrode resistant to cracking and impact. Used for joining and building up thick steel, high-alloy steel, and cast steel — such as extruder screws, roller presses, and coupling boxes. Widely used to repair metals that are difficult to weld.
S717 E A/B/CSpecial Electrodes for Alloy Steel
High-Manganese Steel Electrode for Pre-Hardfacing Rebuild
Covered Electrode
An electrode for repairing and rebuilding components before hardsurfacing, such as railway track, mill hammers, rollers, and crushers, thanks to its high manganese steel content. Can also be used to weld between cast iron and steel. Resists cracking, abrasion, impact, corrosion, pressure, cavitation, and extreme shock — the weld deposit work-hardens further in service. AISI grades: 420, 430, 430T, 431, 440, 502, 405, 410.
