Iron-based alloy powders are self-fluxing powders, mainly composed of iron, chromium, boron, silicon, etc. These powders are mainly used for “wear-resistant mechanical parts” working at temperatures as high as 500°C. Compared to nickel- and chromium-based alloy powders, iron-based powders are more advantageous in terms of costs, and have more application fields.
