Applications and Features

( 1 ) The alloy system provides high strength and good corrosion resistance, resists oxidation, and delivers creep-rupture strength at elevated temperatures.

( 2 ) Ideal for welding materials of similar composition, such as alloys 600, 601 and 800.

( 3 ) Suitable for applications ranging from cryogenic to high temperatures, such as pipeline, furnace equipment, petrochemical and power generation plant.

Welding Position

Welding Instruction
