Selectarc FCW CO21

This is a cobalt-based tubular metal-cored wire specifically designed for gas-shielded hardfacing applications. It’s designated as Cobalt Grade 21 and offers exceptional resistance to wear and corrosion, particularly in sulphurous atmospheres up to 900°C. It’s suitable for a range of demanding applications, including scope and valve seats, hot forging dies, and large hardfacing areas, often employed in gas turbine applications. The wire conforms to AWS A5.21 and EN 14700 standards.

This wire is primarily used for hardfacing applications where high wear and corrosion resistance are critical. It is commonly found in applications such as protecting valve seats, hot forging dies, and large surface areas on gas turbines. Its suitability also extends to environments with sulphurous atmospheres where resistance to corrosion is paramount.
