LIFE 4 Green Steel – HDPM (High Density Powder Metallurgy) yields outstanding results!

On Thursday 7th October 2021 a webinar will be held to present the outcome of the four-year European LIFE program, brought to a successful conclusion in August with results that go beyond expectations. Key results included a component density of up to 7.5-7.7 g/cc and an improvement in environmental performance of over 50%

The production of ultra-high performance steel components that perform better, consuming fewer energy, environmental and process resources: this, in short, was the goal of the LIFE 4 Green Steel project, co-funded by the European Union’s LIFE program and developed by a partnership between SACMI, University of Trento, TFM Automotive Industries (project leader) and K4Sint.

The project - which lasted four years and ended in August 2021 - will be presented as part of an on-line meeting on Thursday 7th October 2021 at 3 p.m. The aim of the webinar is to present the results in detail: these include the ability to make - using wall lubrication pressing (DWL) systems - sintered steel components with a density of between 7.5 and 7.7 g/cc (well beyond the target of 7.3 g/cc).

LIFE 4 Green Steel was set up to demonstrate the industrial feasibility of producing these component types via an HDPM (High Density Powder Metallurgy) process instead of the traditional "chip removal" techniques. This was done by developing a press prototype, in this case the SACMI MPH 200, capable of working in an actual industrial line.
This project was developed against a backdrop of extensive, ever-greater use of such components and the parallel need to develop innovative solutions that limit the use of pre-mixed lubricants, thus reducing consumption and emissions.

From this perspective, LIFE 4 Green Steel has shown that it’s possible to make "nearly finished" components (in this case, steel cogs) via a series of "compaction" steps. This technique increases the utilization coefficient of the raw materials by up to 95% and reduces waste by at least 50%. There’s also a 70% reduction in lubricant use, with a general increase in energy efficiency of 50% compared to a traditional process.

The LIFE 4 Green Steel project is co-funded by the European LIFE program, the European Union’s financial tool for the development of projects for the environment, nature conservation and climate change containment. During the 2014-2020 plan (to which the LIFE 4 Green Steel project belongs) the LIFE program financed over 5,500 projects throughout the EU, delivering resources valued at over €4 billion and driving investments worth over €9 billion.
