SIJ Acroni is one of the leading producers of stainless steel and special steels in Europe. We are part of Slovenia's largest vertically integrated metallurgy group. We are committed to global and European climate goals and operate in line with circular economy principles. With our steel, we are the right partner for facilitating the green transition in Europe. We are a modern recycling mini mill. Our steel is recycled.

We are one of the largest employers in the Gorenjska region, with over 1,300 employees. SIJ Group, with more than 3,800 employees, is also one of the biggest employers in Slovenia and a pillar of the Slovenian steel sector. We are among the leading Slovenian exporters, generating approximately 85 per cent of our revenue in foreign markets.

SIJ Acroni consists of five plants:

  • steel mill, where steel scrap is remelted in the electric arc furnace, refined in converters AOD, VOD or VD and cast on the continuous casting machine;
  • hot rolling mill, where we roll quarto plates and hot-rolled strips;
  • cold rolling mill, where we roll cold-rolled strips and process electrical steel;
  • quarto plate processing, where we process stainless, high-strength, wear-resistant and tool steel quarto plates;
  • raw materials department, where we purify steel scrap through magnetic separation and process black and white slag. Extracted steel is returned into the process, and slag is turned into new products.

Core production programmes include high-quality steel products, such as:

  • stainless steel quarto plates,
  • special steels (high-strength and wear-resistant steels),
  • non-oriented electrical plates,
  • alloyed tool steels (rolled and forged products).

Steel is an important cornerstone of a sustainable world. It is the world's most recycled material. At SIJ Acroni, we process it over and over into new forms of steel. Without loss of value.
