Solid wire for welding creep resistant 0.5%Mo steels and fine grained steels.


Used in chemical plant construction operating at elevated temperatures up to 500°C, also suitable for applications in petrochemical process plant where some resistance to hot hydrogen attack is necessary or for welding of micro-alloyed stels where increased strength is required. 


  • Used for welding low alloy creep resistant ferritic steels and fine grained steels
  • Ideal for low temperature applications in the as welded condition with service temperatures in range -30°C to +500°C
  • Recommended for welding 0.5% Mo low-alloy steels and for high strength steels.

Typical Applications

  • Oil & Gas
  • Thermal Power
  • Petrochemical
  • Chemical

Shielding Gas

  • M21 : Mixed gas Ar+ >15-25% CO2, C1 : Active gas 100% CO2
