FCW B CrMo1
Description & applications
• Seamless cored copper coated tubular wire for gas shielded flux cored arc welding
• Single and multiple pass welding of creep resisting steels alloyed with 1.25Cr-0.5Mo
• Optimal productivity by combining advantages of both seamless and seamed tubular wires
• HDM guaranteed < 4 ml/ 100g deposited metal on the whole parameter box
• No moisture pick up, excellent wire feeding properties, good weldability and low spatter
• Designed for service temperatures up to 550°C
APPLICATIONS
Welding creep-resisting steels of similar composition. Preheat 150-250°C and stress relieving 660 -700°C must be carried out.
