SS17-4PH

MBJ · Gray-Black

The strength and hardness of 17-4PH precipitation hardened stainless steel can be significantly improved through heat treatment after sintering. The color of its printed parts is dark gray to black gray in the sintered state. It has good mechanical properties and moderate corrosion resistance, and is suitable for structural parts that require both strength and precision.

17-4PH Stainless Steel

SLM · Silvery-gray

17-4 PH stainless steel is a martensitic precipitation hardening stainless steel. The material is known for its excellent corrosion resistance and extremely high strength and hardness, especially after heat treatment. 17-4 PH can be adjusted to different hardness and toughness levels through heat treatment, allowing users to tailor the properties of the alloy after sintering to suit a wide range of application scenarios, including: mechanical equipment, chemical processing, food processing, pump components, valves, fasteners, jigs and fixtures.

316L Stainless Steel

SLM · Silvery-gray

316L stainless steel is one of the most commonly used stainless steel grades in 3D printing. Thanks to the extremely high temperature gradient and extremely fast solidification rate during the printing process, the material's mechanical properties after molding are better than traditional castings (although some printers also support printing in 17-4 PH stainless steel). 316L is a metal with strong mechanical properties. The printed surface is usually rough and has pitting (melt pool marks). The material can provide a variety of polished or matte post-processing effects and is widely used in jewelry, functional parts, small sculptures and other fields.
