3D Printing Stainless Steel GP1

3D Printing Technical Parameters

1. The maximum printing size of metal 3D printer: 250x250x325mm;
2. Metal 3D printing printing layer thickness: 0.02mm~0.04mm;
3. Metal 3D printing 3D printing can achieve accuracy: Typical accuracy: ± 0.02-0.05 mm (Accuracy is related to geometry. It varies according to product size, printing direction, materials and post-processing methods.);
4. Post-processing: high temperature annealing, polishing, welding and other processing;

3D Printing Material Characteristics

Stainless steel GP1 is a form of pre-alloyed stainless steel metal powder, and its composition is classified as 17-4 in the United States and 1.4542 in Europe. This type of steel is characterized by good corrosion resistance and mechanical properties, particularly excellent in the state of laser extension treatment, and is widely used in various engineering applications.

*Remarks:

1、1、According to ISO 6892:1998 Mechanical Test (E) Annex C proportional sample, neck diameter area 5mm, original gauge length 25mm.

2, Vickers hardness measurement (HV) is based on DIN EN ISO 6507-1. Please note that depending on the method used for this measurement, the measured hardness value can depend on the surface roughness and can be lower than the true hardness. To avoid inaccurate results, the hardness should be measured on the polished surface.
