Characteristics and application

MIG/GMAW wire for welding high strength low alloy steels. Used for welding high strength steels in many high stress, critical applications; also exhibiting excellent toughness down to -60°C. Typical applications can be found in crane construction, mining, shipbuilding, automotive and pressure vessel industries.

Base materials

For high strength fine-grained structural steels up to yield strength 770 MPa (100ksi).
