Project description:


The production process for high-performance steel components for the automotive industry has a considerable impact on the environment and on human health that could be alleviated with more efficient use of raw materials and energy, and reductions in waste chemicals and greenhouse gas emissions. High-performance steel components, such as gears, are currently produced by a machining technology, mainly due to high requirements in terms of mechanical properties and dimensional stability. The Powder Metallurgy (PM) technology is a sustainable manufacturing process recognised as a green technology and the high mechanical and dimensional requirements above-mentioned could also be theoretically met by means of an innovative Die Wall Lubrication (DWL) compaction stage, in combination with high-temperature vacuum sintering and thermochemical treatment. The DWL compaction process is currently used only in a limited number of applications. It is currently not exploited at an industrial level due to the difficulties of planning, managing and monitoring the productive process.


The aim of the LIFE 4GreenSteel project is to demonstrate the feasibility of replacing the traditional energy-intensive and material-consuming machining of wrought metals with a new and innovative High Density Powder Metallurgy (HDPM) technology for the manufacturing of widely-used high-performance steel components, particularly gears for the automotive market.

Specific technical objectives are to:

  • Develop an effective pressing system, operating with the DWL technique, to produce sintered steel parts that have a density greater than 7.3 g/cc and high dimensional stability;
  • Tailoring the high-temperature vacuum sintering stage and development of a reliable case-hardened profile of PM steel by means of the thermochemical treatment Low Pressure Carburising (LPC);
  • Use a chemical composition for steel avoiding harmful alloying elements (nickel), such as nickel, or alloying elements that make the recycling process difficult and ineffective, such as copper;
  • Reduce by more than 70% the lubricant premixed with metal powder, so eliminating the burning stage, increasing energy efficiency and solving related emission problems; and
  • Achieve energy and material saving through the innovative HDPM technology, which has a very high coefficient of material use (95%) and therefore minimises energy input; and
  • The project actions will contribute to the implementation of the Circular Economy Action Plan, the Roadmap to a Resource Efficient Europe, the Directive on Energy end-use efficiency and energy services, and Decision (406/2009/CE) on Energy Efficiency. Furthermore, LIFE 4GreenSteel is relevant to EU policy on sustainable growth and will also provide European enterprises with tools to enhance their competitiveness.

    Expected environmental results: The LIFE 4GreenSteel project expects to achieve the following results:

  • Reduction in use of raw materials by 47.4% compared to the machining baseline;
  • Energy savings of 50% compared to the machining baseline;
  • Strong reduction of cutting fluids lubricants avoiding machining operations;
  • Reduction of metal powder admixed lubricant by 70% compared to the standard PM baseline;
  • CO2 reduction of 49.3 % compared to the machining baseline;
  • Development of an innovative HDPM process to produce a high-performance steel component from 1 200 to 7 500 pieces/day;
  • Development of at least 300 innovative HDPM steel demonstration components that are able to sustain effective surface treatments;
  • Development of at least 300 PM steel demonstration components without copper and nickel as alloying elements;
  • Elimination of dewaxing/burning process for admixed powder lubricant; and
  • Reduction in production cost in respect to the machining baseline.
