Cogne Acciai Speciali

Cogne Acciai Speciali makes stainless steel long products and nickel alloys in Aosta, Italy. The company has produced steel for more than a century. It makes a wide range of special steels for high-technology sectors, and its products are certified to international standards.

Its work serves the oil and gas, power generation and automotive markets. The company has also gained new certifications for the aerospace and nickel-based product markets. It says its progress comes from research, innovation and in-depth training programmes for its staff, and it runs its own academy.

The Aosta plant covers 560,000 square metres. More than 1,100 people work there full time, and the number rises to about 1,500 with contract staff. Cogne is a major business in the Valle d'Aosta region. It has also built a network of production and sales companies in key areas around the world to support the plant.

In June 2022, Walsin Lihwa Corporation became the 70 percent shareholder. Since then the group has grown through a series of purchases. In August 2023 it took over the Degerfors and Storfors sites of a Swedish maker of stainless steel long products, which strengthened its large-sized bar business. It also completed the purchase of Special Melted Products, a British company, after a capital increase of 200 million euros.

In May 2024 Cogne bought 65 percent of Com.Steel Inox, a company near Bergamo that recovers and treats stainless steel and nickel alloy scrap. In October 2024 it finished buying Mannesmann Stainless Tubes, which has sites in Germany, France, Italy and the United States. After that deal the group reported revenue of 2 billion euros and about 3,000 employees.

Cogne says it works to reduce the environmental impact of its products and processes. It publishes an ESG data hub. It has also earned the UNI PdR 125 certification for gender equality. Customers can read its alloy surcharges and conditions of sale online, and investors have a dedicated section.
