Market Overview

According to Novatrends Market Intelligence, the Global Stainless Steel Powder Market was valued at USD 3.12 billion in 2025 and is anticipated to propel at a growth rate of 8.4% from 2026-2036.

The stainless steel powder market provides gas atomized stainless steel powder, water atomized stainless steel powder, and plasma atomized stainless steel powder products for metal additive manufacturing (3D printing), metal injection molding (MIM), powder metallurgy (PM) press and sinter, thermal spray coating, and surface coating applications. Stainless steel powder for 3D printing (SLM, SLS, DED, binder jetting) is the fastest-growing segment, requiring gas atomized stainless steel powder or plasma atomized stainless steel powder with tight particle size distribution (PSD), high sphericity, low oxygen content, and good flowability for consistent layer deposition in powder bed fusion processes. 316L stainless steel powder (austenitic, 2.5% Mo for corrosion resistance) is the most widely used grade for medical device, marine, chemical processing, and food equipment additive manufacturing and MIM applications. 304 stainless steel powder (austenitic, standard grade) is used in structural, consumer, and industrial PM applications where cost is more important than high corrosion resistance. 17-4 PH stainless steel powder (precipitation hardening) provides high strength and hardness for aerospace and oil and gas stainless steel SLM powder components. 15-5 PH powder and 420 stainless steel powder are used in specialty aerospace, cutlery, and tooling PM and stainless steel SLM powder applications. Stainless steel powder for MIM provides fine (-22 µm) water atomized stainless steel powder for injection molding of complex small stainless steel parts at high volume and low per-part cost. Medical grade stainless steel powder uses 316L stainless steel powder with certified traceability and biocompatibility documentation for surgical instruments, implants, and medical device applications. Fine stainless steel powder for thermal spray and surface coating applications restores worn or corrosion-damaged stainless steel surfaces. Aerospace stainless steel powder (17-4 PH, 15-5 PH) is produced to AMS specifications for structural aerospace AM components. SS powder for sintering (water atomized stainless steel powder) is used in high-volume PM press-and-sinter parts for automotive, appliance, and hardware applications. Stainless steel powder supplier competition includes Höganäs, Sandvik (Osprey), Carpenter Additive, and AP&C (GE Additive). Stainless steel powder market size is driven by metal AM growth and MIM industry expansion globally.

Market Dynamics

The market is driven by metal additive manufacturing growth across aerospace, medical, and industrial sectors creating expanding stainless steel powder for 3D printing and stainless steel SLM powder demand, metal injection molding (MIM) industry growth in consumer electronics, automotive, and medical segments requiring fine stainless steel powder for MIM, and growing PM press-and-sinter application base requiring SS powder for sintering. Gas atomized stainless steel powder production capacity expansion is ongoing at Höganäs, Sandvik Osprey, and AP&C to meet growing stainless steel SLM powder and aerospace stainless steel powder demand. 316L stainless steel powder demand is growing with medical device additive manufacturing and dental implant applications. Stainless steel powder market growth is supported by medical grade stainless steel powder demand from surgical robotics and orthopedic implant AM. Stainless steel powder market trends show growing plasma atomized stainless steel powder premium quality demand for LPBF (laser powder bed fusion) aerospace and medical applications. Water atomized stainless steel powder cost-competitiveness continues to make it dominant for SS powder for sintering and MIM. Stainless steel powder supplier diversification is ongoing globally with new entrants from China and South Korea expanding production. In January 2024, Höganäs expanded 316L stainless steel powder and gas atomized stainless steel powder with new stainless steel SLM powder grades, while Sandvik Osprey advanced 17-4 PH stainless steel powder and aerospace stainless steel powder for metal additive manufacturing powder and stainless steel powder for 3D printing programs. Stainless steel powder market trends show accelerating adoption in aerospace, medical, and oil and gas additive manufacturing applications globally.
