Description
M300 maraging steel powder is an age-hardenable martensitic tool steel specifically engineered for additive manufacturing using LPBF, EBM, and DED processes. Known as 1.2709 tool steel, this alloy delivers exceptional tensile strength and hardness after a simple age-hardening heat treatment.
Unlike high-carbon tool steels such as H13 or M2, which are difficult to process in Laser Powder Bed Fusion due to cracking and instability, M300 maraging steel powder provides comparable mechanical performance with significantly improved additive manufacturing processability.
Strict control of residual alloying elements ensures optimized layer fusion, predictable mechanical properties, and reliable repeatability. After age hardening, M300 maraging steel powder achieves outstanding strength, wear resistance, and heat resistance up to 900°F (482°C).
This combination of strength, hardness, and additive manufacturing compatibility makes M300 maraging steel powder an ideal solution for tooling inserts, molds, and high-load functional components.
