Description

Tubular wire containing Cr, Ni, Mo alloys for welding high strength low alloyed steels.

Preheating temperature required based on equivalent carbon content and work piece thickness

Suitable for Welding S690 and HSLA steels

Good Impact resistance (even at -30°c)

Suitable for road construction equipment, cranes equipment and structures under high tensile stress

Probable occurrence of lower strength and tenacity in HSLA steels if inter-passing temp exceeds 200°c
