Fluoride-basic type, agglomerated submerged arc welding flux with high basicity, it is designed for the welding of high strength fine grained structural steels, cryogenic steels and steels, resistant to ageing. Generally used for the welding of thick sections in the offshore, wind tower, nuclear and pressure vessel industries. Provides very high toughness values at low temperatures, in combination with approved wires. Due to it's high current carrying capacity and good operating characteristics both on alternative and direct currents, possible to use in one side welding and two side welding processes by single or multi-wires (tandem/twin). Owing to it's neutral behaviour, it is advisable to use wire electrodes having higher manganese and silicon content in tandem and multi wire applications. Has high penetration, smooth weld beads with high X-ray quality.
