IMT 316L stainless steel powder 15–53 µm, 5 kg

IMT 316L 15–53 µm: Stainless Steel Powder for Printing Corrosion-Resistant Parts

IMT 316L is a low-carbon austenitic stainless steel alloyed with molybdenum, making it significantly more resistant to corrosion compared to standard steel grades. Due to its biocompatibility and ability to withstand aggressive environments (saltwater, acids), this powder is an ideal material for SLM/LPBF 3D printing in medicine, shipbuilding, and the chemical industry.

The 15–53 µm fraction powder ensures high precision in reproducing fine elements and excellent surface quality of finished products.

Material Technical Profile

Chemical Composition

The alloy composition is strictly controlled to achieve maximum resistance to pitting corrosion:

• Iron (Fe): base (Bal.) — the basic component of the alloy.
• Chromium (Cr): 17.0% — provides high oxidation resistance.
• Nickel (Ni): 12.0% — stabilizes the austenitic structure and increases ductility.
• Molybdenum (Mo): 2.5% — a key element that gives 316L steel exceptional resistance to aggressive chloride environments and seawater.
• Manganese (Mn): ≤ 2.0%.
• Silicon (Si): ≤ 1.0%.
• Carbon (C): ≤ 0.03% — low content prevents intergranular corrosion.
• Oxygen (O): ≤ 0.06%.
• Phosphorus (P): ≤ 0.045%.
• Sulfur (S): ≤ 0.03%.

Physical Characteristics of the Powder

Morphology indicators ensure the stability of the printing process:

• Size distribution: 15–53 µm.
• Hall flow: ≤ 18 s/50g.
• Apparent density: ≥ 4.0 g/cm³.
• Tap density: ≥ 4.5 g/cm³.
• Oxygen content: ≤ 600 ppm.
• Sphericity: ≥ 85% — ensures uniform layer application of metal.

Mechanical Properties

Data confirms exceptional toughness and the material's ability to deform without breaking:

• Tensile strength: 550–600 MPa.
• Yield strength: 230–280 MPa.
• Reduction of area: 60–70%.
• Elongation: ≥ 50%. Such a high indicator demonstrates the material's extraordinary ductility, allowing parts to withstand significant deformation loads.

Application Areas and Examples of Parts

Thanks to the combination of mechanical strength and chemical inertness, IMT 316L is used for creating:

• Medicine: manufacturing surgical instruments, orthopedic implants, and custom medical devices requiring biocompatibility.
• Marine Industry: ship equipment components, heat exchangers, and fasteners constantly in contact with saltwater.
• Chemical and Oil & Gas Industries: pump parts, fittings, valves, and reactors where resistance to aggressive substances is crucial.
• Jewelry and Watch Industry: watch cases, complex bracelets, and jewelry (the material does not cause allergic reactions on the skin).

Packaging: airtight container 5 kg.
