Key Characteristics of Metal raw material iron base alloy stainless steel 304L 316L powder
-
Particle Size and Distribution: The size and uniformity of particles significantly influence flowability, packing density, and the final product’s mechanical and physical properties. Finer powders generally offer a larger surface area, which is beneficial for reactions and sintering but may also increase aggregation.
-
Composition: Metal powders can be elemental (pure metal) or alloyed, combining two or more metals to achieve desired properties such as enhanced strength, corrosion resistance, or electrical conductivity.
-
Shape: Particle shapes range from spherical to irregular or flake-like. Spherical powders provide better flowability and packing, while flake-shaped powders are suited for coatings and electronic applications due to their unique orientation and surface area.
-
Purity: Depending on the application, metal powders can be highly purified to remove impurities, critical for uses in electronics, aerospace, and medical devices where contamination could compromise performance.

– Sulfur (S): Max 0.035%
– Other elements: Copper (Cu), Silicon (Si), and other trace elements.
2. Properties:
– Both 304L and 316L have excellent corrosion resistance due to the presence of chromium and nickel, which form a passive oxide layer on the surface.
– 316L is more resistant to pitting and crevice corrosion than 304L because of the addition of molybdenum.
– They are also highly resistant to chloride ion-induced corrosion, making them suitable for marine environments and harsh chemical applications.
– They have good mechanical properties like tensile strength, yield strength, and ductility.
3. Particle Size Distribution:
– Stainless steel powders are typically available in various particle sizes, usually ranging from 40 mesh (75 microns) to 200 mesh (45 microns) or even finer, depending on the application and manufacturing process.
4. Processing Parameters:
– Depending on the intended use, these powders may require specific processing techniques such as gas atomization, mechanical milling, or electrode arc melting.
– The particle size and shape can affect flowability, packing density, and sintering behavior.
– Sintering temperatures and time will vary based on the specific powder and the desired end product.
5. Environmental Impact:
– Stainless steel powders are recyclable and environmentally friendly, contributing to sustainability efforts in industries that use them.
Please note that actual specifications may vary slightly between manufacturers, so it’s essential to consult the supplier’s datasheet for precise details.
