This technology relates to Fe-based alloy powders for powder metallurgy components used as anti-abrasives, and to applications in the manufacture of rolling rolls and press rollers. In particular, it is a technology designed to enhance performance, durability, stability, and applicability based on key materials, structures, processes, or device configurations related to Fe-based alloy powders for wear-resistant parts.
This invention aims to resolve the limitations of alloy component content in solidification carbides and component separation in tool steel materials while maintaining excellent wear resistance and toughness. Accordingly, this technology proposes a technical concept that implements the control of micro-structures having controlled volume percentages of MC carbides and M2C carbides by applying impurities containing 5.0–5.5 wt% chromium (Cr), 0.5–1.0 wt% manganese (Mn), 0.5–1.0 wt% silicon (Si), 3–6 wt% molybdenum (Mo), 6–8 wt% vanadium (V), and 1.5–1.9 wt% carbon (C) as a core means.
Accordingly, this invention is expected to improve the wear resistance and toughness of tool steel materials in warm environments below 500°C while maintaining competitive production costs, and can simultaneously enhance reproducibility, scalability, and process suitability in actual usage environments. Furthermore, it can be utilized as a high-performance material, component, battery, sensor, device, or manufacturing process in related industries, making it advantageous in terms of subsequent commercialization and demonstration development.
