This micro-alloyed steel wire (ER 70S‑2 / W2Ti) is a triple de-oxidised electrode with Ti, Al, and Zr, designed for welding C-Mn and low-alloy steels. It performs exceptionally well on greasy, oxidised, or coated surfaces — including galvanised steel — making it ideal for challenging fabrication conditions.
Engineered for versatility, this wire maintains weld quality even at low temperatures and is widely used in industries such as automotive, structural fabrication, household appliances, pipelines, boilers, naval, and petrochemical sectors. Green wire production uses virgin raw materials from specialised steel mills, ensuring consistent reliability, high quality, and excellent mechanical properties.
