OCAS/ArcelorMittal Global R&D Gent
Within ArcelorMittal, OCAS is known as ArcelorMittal Global R&D Gent and is as such in charge of all ArcelorMittal R&D projects within the market of general industry for flat carbon steel. 90% of OCAS’ R&D activities are linked to 3 key themes: energy, environment and the durability of materials. OCAS develops new steel grades and coatings for the following markets: energy pipes and tubular products, heavy plates, white, brown, yellow and green goods, appliances, metal processing and construction.
OCAS is equipped with state-of-the-art R&D tools and facilities in its laboratories in Zelzate and Gent-Zwijnaarde (Belgium), for example to test sour properties and H-embrittlement of steels, which will be used in this project. As a research centre for ArcelorMittal steel product development, OCAS possesses pilot scale facilities for casting (from a few grams up to 100 kg), rolling and several heat treatments as well as a broad range of characterisation tools, both for mechanical properties as for standard microstructural characterisation. In particular, OCAS has developed methodologies for accelerated screening, processing and characterization of metal alloys, which will be used in this project for screening a large number of generic alloys, in order to get a better understanding of the intermetallic precipitation strengthening.

Aubert & Duval
Aubert & Duval’s scope of activity is wide, covering both the raw materials melting processes, i.e. alloy making, and the full array of processes that can be applied to thermo-mechanical transformation and heat treatment of alloys. Aubert & Duval’s profile fits perfectly for the project as it is an experienced special steels producer and particularly for stainless maraging steels. Regular productions of 15-5PH, PH13-8Mo steels and derivatives for the aerospace industry are performed in a large variety of items, from long products to closed die parts. Its R&D is continuously developing new steels with improved mechanical resistance such as MLX17® and ML340® and gained experience on past projects on manufacturing routes for these new alloys.In addition, A&D has the availability of a significant infrastructure and technical equipment relevant to the proposed work (steel shop, special vacuum melting shop, vacuum remelting furnaces, hydraulic presses for open die forging, close die forging press and multiple facilities for heat treatment, machining & mechanical testing).

Liebherr-Aerospace
Through its experience in the design and production of landing gear systems for modern aircraft, Liebherr has reached a high level of product knowledge and production competences in high quality landing gears (EMBRAER ERJ170/190, COMAC ARJ21, C919 BOMBARDIER C-SERIES, AIRBUS A350 Nose Landing Gear). Liebherr will support the project through its aerospace expertise as end user. Thanks to its own serial production facilities, Liebherr has real scale production equipment available such as furnaces, milling, turning and drilling machines and required tooling to assess the major steps of the production process of a future stainless landing gear.
