EOS expands its metal AM materials portfolio with four new materials

1 min read

EOS, a leading supplier for responsible manufacturing solutions via industrial 3D printing technology, has today 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 states: “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.”

For extreme conditions: EOS StainlessSteel 254

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 material is particularly suited for applications such as chlorinated seawater handling equipment, pulp, and paper manufacturing devices as well as chemical handling equipment.

For difficult environments: EOS StainlessSteel SuperDuplex

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. Its high chromium, molybdenum and nitrogen alloying give excellent corrosion resistance in many difficult environments.

For use at elevated temperatures: EOS ToolSteel CM55

EOS 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. Its alloying elements and moderate carbon content form a strong and stable structure for demanding applications and for the use in elevated temperatures.

For use at elevated temperatures:  EOS NickelAlloy HAYNES 282

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.

It was developed for high temperature structural applications and is manufactured under license from Haynes International Inc. Typical applications range from aerospace and rocket engine components to turbomachinery and gas turbine parts, and to energy industry components.

TRL 3 Core materials: the EOS Quality Triangle

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.
