Industries such as automotive, mechanical engineering, and hydraulics rely heavily on the quality and versatility of these steels. Traditionally, lead was added to improve the machinability of these steels. However, the Swiss Steel Group is now taking a new approach by replacing lead with the more environmentally friendly element boron.
The Swiss Steel Group leads the way in innovation by relying on the electric arc furnace (EAF) process, one of the lowest CO?-emission steel production methods available. Unlike conventional blast furnaces that depend on carbon-intensive raw materials like coal and iron ore, the electric arc furnace primarily uses recycled scrap metal as its raw material.
This process significantly reduces CO? emissions and offers the possibility of almost entirely eliminating the use of fossil fuels. By utilizing renewable energy sources, the EAF process can further optimize the CO2 footprint, making it one of the most climate-friendly steel production methods available.
The decision to prioritize the electric arc furnace process and the ongoing development of lead-free alternatives like 11SMn30+BX highlights how the Swiss Steel Group proactively contributes to the transformation of the steel industry. "We are proud to further strengthen our leadership in sustainable steel production," states Frank Koch, CEO of the Swiss Steel Group.
The “11SMn30+BX” machinable steel delivers the usual high performance and superior machining quality – essential for producing small, precise components. Customers benefit from the product’s consistent quality, which reduces maintenance intervals and increases uptime. These advantages help lower production costs and enhance the competitiveness of customers.
Applications of “11SMn30+BX”:
– Automotive Industry: Ideal for small, precise components that require high machinability and environmental sustainability, such as engine and chassis parts.
– Mechanical Engineering: Perfect for machines and tools that demand a long lifespan and high durability.
– Hydraulics: Suitable for demanding applications that require accuracy and surface quality.
As a global leader and winner of the German Sustainability Award 2024, the Swiss Steel Group also offers all its products in CO2-reduced Green Steel quality. The “11SMn30+BX” represents another step toward a low-carbon steel industry and showcases the company’s forward-thinking, sustainable approach.
