Description of Self-Flowing/Melting Alloy Powder HRFe30
Self-flowing/Melting alloy powder based on iron, HRFe30, is recommended for applications where the component may deform as a result of melting following coating, or where the substrate does not tolerate the heat generated during the melt process. Self-flowing/Melting materials partially melt during the spraying process, thereby eliminating the need for subsequent remelting.

Applications for Self-Flowing/Melting Alloy Powder HRFe30
- Flame spraying/Melting
- HVOF
- Fatigue resistance
These self-melting alloy powders based on iron are designed for use in a two-step spraying/melting process on metal surfaces applied to iron components, where corrosion resistance and wear resistance are required to be increased. They may be applied to parts and components manufactured from carbon steel, alloyed and stainless steels, cast iron, Monel, nickel and cobalt alloys. They must not be applied to brass, bronze or aluminium and may require special precautionary measures when used with certain other alloys. Given that the selected type influences performance, the process yields a coating hardness ranging from HRC 33 to 65.
