Other low-alloy steels are also available. Contact us to discuss Sandvik's full range of metal powder alloys.

The thermal spray powder is also suited for flame spraying or metallizing, without subsequent fusion of the coating. Good surface preparation is fundamental to the success of this process and the application of a bond coat (SB 80) is recommended.
