Introduction: Why Maraging Steel Powder Matters in Advanced Manufacturing
Maraging steel powder is rapidly becoming a vital material for industries that demand high strength, excellent toughness, and dimensional stability in their components. Known for its outstanding mechanical properties and minimal distortion upon heat treatment, maraging steel is a preferred choice in aerospace, defense, automotive, and tooling sectors—especially in the domain of additive manufacturing (AM).
Unlike traditional alloy steels, maraging steels are low-carbon iron-nickel alloys that derive their strength not from carbon hardening but through age-hardening (precipitation hardening). This makes them particularly suitable for 3Dプリンティング technologies like Selective Laser Melting (SLM), Electron Beam Melting (EBM), and Direct Metal Laser Sintering (DMLS).
For B2B buyers, such as OEMs, part manufacturers, and powder distributors, sourcing high-quality maraging steel powder ensures not just product performance but also reliability and long-term cost efficiency. With increasing demand for metal additive manufacturing, especially in high-performance sectors, the global maraging steel powder market is expected to witness substantial growth over the next decade.
At the forefront of this innovation is 上海Truer科技有限公司, a leading supplier of metal 3D printing powders and powder-making equipment. Established in 2009 and entering the additive manufacturing industry in 2019, Truer provides advanced solutions for maraging steel powder production using Plasma Rotating Electrode Process (PREP) and Selective Electron Beam Melting (SEBM) technologies.
