Stainless Steel 3D Printing: most popular and strong

Stainless steel powder is one of the most popular metals used in 3D printing . It provides a series of excellent characteristics to ensure the molding of metal parts: corrosion resistance, wear resistance, conductivity, etc. The market price of stainless steel powder is relatively low, making it the main material basis for parts and components in various industries.

What stainless steels are available for additive manufacturing?

In 3D printing, the affordability of stainless steel powder enables the creation of high-strength metal parts and spare parts. At LUSHI, we provide customers with two types of stainless steel with different properties, namely 316L and 17-4PH. Stainless steel alloy 316L (1.4404) is relatively resistant to corrosion, and alloy 17-4PH (1.4542) is characterized by high strength and hardness.
High corrosion resistance
High impact resistance and strength
High thermal conductivity
Excellent sustainable development
Good for Aesthetic appearance
Very good hygiene

316L(1.4404)
Particularly corrosion-resistant for 3D printing parts

The corrosion resistance of stainless steel powder generally increases as the chromium content increases. Since there is enough chromium in the steel, a very thin and dense oxide film is formed on the surface of the steel, which can prevent further oxidation or corrosion. 3D printing 316L steel has added molybdenum element, so its resistance to pitting corrosion in marine and chemical industrial environments is much better than ordinary stainless steel. Even in the metal 3D printing process at temperatures up to more than 300 degrees, 316L stainless steel can still resist intergranular corrosion.

Industrial applications: Automobile, tooling, Aerospace, Energy, Jewelry.
Max. building volume: 425*425*525mm

17-4PH(1.4542)
High Strength for 3D printed parts

17-4PH is a martensitic precipitation hardening stainless steel with high strength, hardness and moderate corrosion resistance up to 600°F. It has good manufacturing characteristics and can be age hardened using a single heat treatment in the temperature range of 900-1150°F. In the field of metal additive manufacturing , parts made of 17-4PH stainless steel have high strength and ductility, and can be subjected to post-processing such as welding, heat treatment, sandblasting, polishing or coating.
