Bohler Fox 20 MVW (Creep Resistant) Low Alloy Steel Stick Electrodes
Used in high-temperature environments, specifically for turbine and boiler construction in power plants, as well as applications across the chemical industry. The electrode is optimised for long-term use under severe creep conditions at design temperatures up to 650 °C. It provides exceptional creep rupture strength and excellent material toughness under prolonged stress. It is preferred for welding similar alloyed creep-resistant steel grades, forgings, and castings.
