Self-flowing/Melting Alloy Powder HRFe55 Description
Self-flowing/Melting Alloy Powder on an iron base HRFe55 is used in cases where the component might deform due to melting after coating or where the substrate cannot tolerate the heat generated during the melting process. Self-flowing/melting materials partially melt during the spraying process, thereby eliminating the need for a separate remelting stage.

Self-flowing/Melting Alloy Powder HRFe55 Applications
- Flame spraying/melting
- HVOF
- Eggen components
- Hook-tooth elements
- Petroleum drill pipe
- Scraper shaft
These self-flowing alloy powders on an iron base are designated for two-stage spraying/melting of metal surfaces on iron components, where corrosion and/or wear resistance is quantitatively required. They can be applied on parts and components constructed from carbon steel, alloyed and stainless steel, cast iron, Monel, nickel and cobalt-based alloys. They cannot be applied to brass, bronze or aluminium and may require special precautions when used on some other alloys. Given that the selected grade is appropriate, a coating hardness ranging from HRC 33 to 65 is achieved.
