Descripción y aplicaciones

• Seamless cored copper coated tubular wire for gas shielded flux cored arc welding

• 9Cr-1Mo deposit modified with niobium and vanadium additions

• Tightly controlled weld metal chemistry provides strength, toughness, fatigue life, oxidation resistance and corrosion resistance at elevated temperatures

• Enhanced productivity, improved weldability, better wetting properties compared to solid wires

• Excellent weld metal quality and X-ray soundness

• HDM < 4ml/100g deposited metal on the whole parameter box


FCW B P91 is designed to weld to weld 9CrMo modified creep resisting steels (P91/T91) with small additions of niobium, vanadium and nitrogen to give improved long term creep properties
