Gas atomized powder for additive manufacturing
Additive manufacturing is the revolution in manufacturing technology! Especially in this promising segment, we as voestalpine BÖHLER Edelstahl can build on our extensive materials experience and expertise in the field of powder metallurgy.
Why to buy at voestalpine BÖHLER Edelstahl?
Customized alloys depending on your requirements. We atomize BÖHLER standard grades, theoretical selection of 250 grades.
voestalpine BÖHLER Edelstahl leverages the metallurgical knowledge and manufacturing options of a special steel producer for this new technology.
Powder is produced on latest atomization techniques and tested in-house. Vacuum induction melting and atomization under inert gas ensure highest product quality.
Depending on the steel grade and customer requirements, raw materials molten under vacuum or remolten can be used. This ensures the highest quality standards and minimizes undesired impurities.
Depending on the requirements of the specific AM process used, we can provide the appropriate particle fraction in a range from 15-150μm.
M789 AMPO Development
Additive Manufacturing offers a multitude of advantages over conventional manufacturing methods like design freedom, shorter lead times or zero tooling costs. However, up to now there has been only a limited number of commercial alloys available for additive manufacturing.
We as voestalpine BÖHLER Edelstahl use our extensive materials experience for the development of customer-specific powder variants. Like our newly developed BÖHLER M789 AMPO.
This patent pending alloy combines the easy printability of a maraging steel with the corrosion resistance of a 17-4PH. The M789AMPO requires no preheating during the printing process and reaches 52 HRC by applying a simple heat treatment.
