IMT 17-4PH Stainless Steel Powder 15–53 µm, 5 kg

IMT 17-4PH 15–53 µm: Stainless Steel Powder for Printing Ultra-Strong and Wear-Resistant Parts

IMT 17-4PH — is a martensitic stainless steel with precipitation hardening, combining exceptional mechanical strength, high hardness, and reliable corrosion resistance. Thanks to its ability for thermal strengthening, this powder is an ideal choice for SLM/LPBF 3D printing of parts that operate under extreme loads in aviation, energy, and tool manufacturing.

The powder fraction 15–53 µm ensures high precision in constructing complex geometric shapes and excellent density of finished products.

Material Technical Profile

Chemical composition

The alloy composition includes copper and niobium, allowing for heat treatment to achieve maximum mechanical performance:

• Iron (Fe): base (Bal.) — basic component.
• Chromium (Cr): 16.5% — provides high corrosion resistance.
• Nickel (Ni): 4.5% — increases the toughness and strength of the alloy.
• Copper (Cu): 4.0% — key element for precipitation strengthening.
• Manganese (Mn): ≤ 1.0%.
• Silicon (Si): ≤ 1.0%.
• Niobium (Nb): 0.3% — contributes to structure stabilization and increased hardness.
• Carbon (C): ≤ 0.07%.
• Oxygen (O): ≤ 0.06%.
• Phosphorus (P): ≤ 0.04%.
• Sulfur (S): ≤ 0.03%.

Physical Characteristics of the Powder

Indicators of morphology and flowability are optimized for stable layer application:

• 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 material feeding and melting.

Mechanical Properties

The material demonstrates exceptionally high strength indicators:

• Tensile strength: 1390–1450 MPa. This is one of the highest indicators among steels, allowing parts to operate under intense stress.
• Yield strength: 1170–1220 MPa.
• Reduction of area: 35–50%.
• Elongation: ≥ 11%. Even with ultra-high strength, the alloy maintains a sufficient level of plasticity, ensuring structural reliability.

Application Areas and Examples of Parts
