Swiss Steel supplies Green Steel Climate +

The Metal 3D Printer technology demonstrator has been developed by an industrial team led by Airbus Defence and Space SAS under contract to ESA ’ s Directorate of Human and Robotic Exploration . The printer will be printing using a type of stainless-steel commonly used in medical implants and water treatment due to its good resistance to corrosion .

Tenova LOI Thermprocess decarbonizes modern HPH ® -BAF

Swiss Steel will supply its proprietary Green Steel Climate + products to Schwäbische Formdrehteile ( SFB Group ). Swiss Steel and SFB previously conducted a joint workshop with a focus on production using Swiss Steel ’ s XTP , Xtreme Performance technology . This technology enables the thermomechanical rolling of almost any conventionally produced standard steel , according to Swiss Steel . An ultra-fine microstructure (< 5 µ m ) can be created through the targeted application of heat and force . This production technique emphasises property characteristics in the material that can otherwise only be achieved by using higher alloy contents or complex , cost-intensive additional operations . SFB and Swiss Steel have agreed to exclusively source Green Steel Climate + from the plants in Switzerland ( Steeltec ) and Germany ( Deutsche Edelstahlwerke Speciality Steel ) from January 2024 .

ESA launches first metal 3D printer on ISS

Metal 3D printing will soon take place in orbit for the first time . A pioneering European-made metal 3D printer is on its way to the International Space Station on the Cygnus NG-20 resupply mission which launched recently . Once arrived at the International Space Station , European Space Agency ( ESA ) astronaut Andreas Mogensen will prepare and install the approximately 180 kg Metal 3D printer in the European Draw Rack Mark II in ESA ’ s Columbus module . After installation , the printer will be controlled and monitored from Earth , so the printing can take place without Andreas ’ s oversight .

Tenova LOI Thermprocess has proven that CO2-neutral heat treatment can go together with low nitrogen oxide ( NOx ) emissions in a cooperation project with thyssenkrupp Hohenlimburg GmbH . At thyssenkrupp ’ s Hagen-Hohenlimburg site , Tenova LOI Thermprocess ’ s latest generation heating hoods with LOI ’ s patented Ultra low NOx HPH ® -flameless concept has been proving its worth for around 12 years . By significantly increasing air preheating temperatures to 600 ° C , this innovative technology has led to energy and therefore CO2 savings of up to 12 %. For the first time in the world , 70 t of steel strip were heat-treated in a bell-type annealing plant with Tenova LOI ’ s HPH ® -flameless technology in a locally CO2-neutral process . The flameless concept results in remarkably low NOx emissions . It has been proven that the particularly efficient Ultra low NOx HPH ® -flameless bell-type annealing plant from LOI Thermprocess is ideally suited for use with hydrogen . Up to 2600 kg of CO2 can be saved per annealing cycle by using regenerative produced hydrogen , while maintaining productivity and product properties .
