Böhler Union S 2 NiMo 1 – UV 420 TTR-C

Böhler Union S 2 Si – UV 418 TT Specifications and Typical Applications

Union S 2 Si – UV 418 TTIt is an agglomerated fluoride-based powder with high basicity and neutral metallurgical behavior.

• Suitable for single (AC and DC) and tandem (DC and AC or AC and AC) power sources.
• It provides excellent slag separation even in tightly spaced welds.
• It is particularly suitable for multi-pass butt welding of medium and high-strength steels.
• It provides very good notch impact toughness in the weld metal at low temperatures.
