Product name：KM-55
 
Classification：ER80S-G
 
 

  1. KM-55 is suitable for welding 490, 520, 540N/mm2 grade steel at high current and interpass        temperature.
  2. Due to special alloy content, it will provide excellent weldability, stable arc, low spatters and        mechanical properties with higher heat input and interpass temperature.
  3. Ideal for welding pillars and beams at high current.
