EOS Expands Metal AM Materials Portfolio with Four New Materials

Krailling/Munich, Germany, July 14, 2022 – EOS announced the introduction of four new metal materials for additive manufacturing (AM) on the EOS M 290 metal system, including two stainless steels, one tool steel and one nickel alloy.

Sascha Rudolph, SVP BU Metal Materials at EOS said, “Material development is always driven by customer demand and very often is the result of a close customer cooperation. These four new metal materials were designed and optimized specifically to the needs of additive manufacturing. We are increasing application opportunities for demanding industries by bringing AM tailored alloys to our customers.”

• EOS StainlessSteel 254 is an austenitic stainless steel that comes with a 40/60 µm process for the EOS M 290 system. The high chromium, molybdenum and nitrogen alloying give excellent corrosion resistance in many difficult environments.
• The EOS StainlessSteel SuperDuplex comes with a 40/80 µm process for the EOS M 290 system. This is an austenitic-ferritic duplex stainless steel optimized for additive manufacturing while maintaining super duplex properties.
• OS ToolSteel CM55 comes with a 40/80 µm process for the EOS M 290 system. It is a cobalt-free, ultra-high strength, and high hardness steel for tooling and engineering solutions.
• EOS NickelAlloy HAYNES® 282® is a nickel alloy powder intended for manufacturing parts on EOS metal systems. It is a precipitation strengthened nickel-base superalloy with a unique combination of high temperature strength, thermal stability, good corrosion, and oxidation resistance, easy fabricability and excellent weldability. 

EOS uses an approach that is unique in the AM industry, taking each of the three central technical elements of the production process into account: the system, the material, and the process. The data resulting from each combination is assigned a Technology Readiness Level (TRL) which makes the expected performance and production capability of the solution transparent. EOS incorporates these TRLs into two categories: premium products (TRL 7-9) offer highly validated data, proven capability, and reproducible part properties. Core products (TRL 3 and 5) enable early customer access to newest technology still under development and are therefore less mature with less data. All of the above materials have a TRL 3 Core classification.
