Powder for additive manufacturing

Whether in aviation, medical technology, toolmaking or lightweight automotive construction. Additive manufacturing is on the rise and high-quality metal powders are essential. We offer a wide range of gas atomised metal powders based on Fe, Ni and Co.

Iron-based metal powder

Our iron-based metal powders for 3D printing can be categorised into austenitic, hardenable and martensitic grades. The austenitic grade Printdur 4404 has high corrosion resistance and good oxidation resistance. The grades Printdur 4545 and Printdur 4548 have the optimum combination of wear, corrosion and oxidation properties. The grades Printdur Powderfort, Printdur 2343 and Printdur 2344 are a good choice for increased wear stress.

Nickel-based metal powder

Our nickel-based metal powder is ideal for applications that require high corrosion resistance. Printdur Ni625 has good resistance to mineral acids such as nitric, phosphoric, sulphuric or hydrochloric acid. It is also corrosion-resistant to alkalis and organic acids. In the solution-annealed condition, the material also has good resistance to hot gas corrosion and a high creep rupture strength above 600°C.

Cobalt-based metal powder

Our cobalt-based metal powder (Printdur CoCrF75) can be used in two different areas: High temperature applications and medical technology. Printdur CoCrF75 has excellent resistance to thermal shock in the heat-treated state and is resistant to oxidising and reducing atmospheres up to approx. 1150 °C. Its properties also include very good biocompatibility and corrosion resistance.

Our Bainidur AM

Our Bainidur AM (= Additive Manufacturing) expands the portfolio of metal powders.

There are currently only a few low- and medium-alloy steels available on the market that can be processed using additive manufacturing. Bainidur AM, on the other hand, fulfils this need as it enables fast and efficient printing of initial samples that also exhibit the subsequent component properties. Heat treatment and thermochemical surface treatments can be tested and optimised using the same material as in series production.

Even spare parts, if the forging dies no longer exist, can be produced using additive manufacturing with the same properties as the original. This is supported by its good transformation behaviour in the bainite structure. This makes the material easy to handle during powder production and printing.

We would be happy to advise you on the optimum selection of the right metal powder.

Climate-neutral steel production

With our Green Steel, we are taking an important step towards climate-neutral steel production. Scrap steel is used as the main raw material and the steel is produced using the electric steel process with energy sources with a low CO2 content. This results in a CO2 footprint well below the industry average.

Medidur - The material for additive manufacturing in medical technology

Whether implants, dentures, orthoses or prostheses - additive manufacturing is essential for medical technology. The newly developed material Medidur is an austenitic, patent-pending steel powder for additive manufacturing. The use of manganese eliminates the need for nickel. The material is non-magnetic, corrosion-resistant and offers high strength, which is particularly advantageous for medical applications. In addition, employees and patients are not exposed to nickel.

The advantages of Medidur® at a glance

Good processability using LPBF. The typical processing parameters of 316L can be used.
Medidur® is manufactured without the alloying element nickel. This means that the safety requirements during processing of the powder are significantly reduced.
By dispensing with the nickel element, Medidur® can be used for medical purposes.
Significantly increased yield strength, tensile strength and hardness compared to typical austenitic steels (e.g. 316L).
A high PREN (Pitting Resistance Equivalent Number) of 36 (316L = 28) and therefore very good corrosion resistance.
High tendency to work hardening.

The properties of Medidur® in combination with our production in accordance with DIN EN ISO 13485 (quality management for medical products) make Medidur the first choice for applications in medical technology.

Swiss Steel Group consistently implements planned capacity adjustments

Lucerne, 15 November 2024 | Swiss Steel Group is adjusting its capacities due to the current eco-nomic conditions and the persistently weak demand. At the same time, the realignment of the en-tire sales organization will continue as planned. Specifically, capacities in Switzerland and abroad are to be reduced to the extent of around 800 full-time positions.
