Dual Shield CrMo2

Dual Shield CrMo2 is an all‑position rutile, low‑hydrogen flux‑cored wire for welding 2.25%Cr/1%Mo creep‑resisting steels. Designed for use with Ar/CO₂ shielding gas, it delivers flat beads, good wetting and impact toughness down to -20 °C after stress relieving.

Key Features

• Gas‑shielded flux‑cored wire (FCAW/MCAW) for low‑alloy steels
• Excellent weldability with flat, smooth beads
• High impact toughness (-20 °C) after PWHT
• Compatible with M21 shielding gas (Ar/CO₂)
