Hunedoara Steel Works Industrial Heritage and Impact

Hunedoara Steel Works has a rich industrial heritage that spans over a century. Established in 1873, it was one of the first steelworks in the Austro-Hungarian Empire.

The steelworks played a crucial role in the region's economy, providing employment opportunities for thousands of people.

During its peak, Hunedoara Steel Works produced over 1 million tons of steel per year.

The steelworks was a major contributor to Romania's industrialization efforts in the early 20th century.

Transylvania united with Romania in 1918, and the works became the Hunedoara Ironworks, a mining and steel-making center with considerable holdings of raw materials and output capacity.

The plant had five tall furnaces producing 119,000 tons of steel per year, and a workshop for moulding cast iron pieces with a 1500 ton-a-year capacity.

Starting in 1926, engineers and economists pushed for increased output, aiming to use the plant to its fullest capacity and refine cast iron to a higher degree.

Between 1937 and 1940, a modern steel production and rolling section was built, with machinery imported from Nazi Germany, covering 8500 square meters and featuring four special components.

The plant employed workers from surrounding villages and peasants from Moldavia and Muntenia, spurring the city's growth from 4800 residents in 1930 to almost 90,000 in 1990.

Hunedoara was the leading Romanian producer of long steel profiles, made in two electric arc furnaces with a combined capacity of up to 550,000 tons per year.

The ArcelorMittal Hunedoara steel plant, located in Hunedoara, Romania, operates under ArcelorMittal ownership with an annual production capacity of 800,000 tons of crude steel.

In 1926, engineers and economists proposed increasing output to the maximum level, which was achieved by using the plant to its fullest capacity and refining cast iron to a higher degree. This led to the production of steel and laminated products.

The Hunedoara Ironworks had a number of facilities, including a workshop for moulding cast iron pieces with a 1500-ton-a-year capacity, a forge equipped with two steam hammers, and a machine workshop for preparing 500-600 tons per year of moulded or forged pieces. These facilities were crucial for producing the necessary components for steel production.

Between 1937 and 1940, a modern steel production and rolling section was built, with machinery imported from Nazi Germany. The new section covered 8500 square meters and was fitted with four special components.

The four Siemens-Martin open-hearth furnaces, heated by six gas generators, could each fit 25 loads of tons, with a total capacity of 90,000 tons of steel ingots per year.

Hunedoara's population grew rapidly during the Communist era, increasing from 4800 residents in 1930 to almost 90,000 in 1990.

The city's growth was fueled by the forced industrialization drive of the decade-old Communist regime, which brought in workers from surrounding villages and peasants from Moldavia and Muntenia.

By 1957, Hunedoara had more than 36,000 residents and was becoming a factory town.

The plant, known as the Hunedoara Steel Works (Combinatul Siderurgic Hunedoara; CSH), was the main driver of this growth, employing a large workforce.

The city's dependence on a single industry made it the country's largest city reliant on a single industry by the 1980s.

Production at the steel works reached its peak in 1982-84, before stalling during the regime's last years.

Hunedoara was the leading Romanian producer of long steel profiles, with two electric arc furnaces producing a combined total of up to 550,000 tons per year.

The first furnace had a capacity of 150,000 tons per year, while the second had a capacity of 400,000 tons per year.

There were also two open hearth furnace steel mills, with the first producing up to 300,000 tons of light profiles per year and the second producing a staggering 3.2 million tons per year.

The Hunedoara Steel Works has a rich history that spans over a century. Transylvania united with Romania in 1918, and the works were renamed the Hunedoara Ironworks (UFH) the following year.

The Hunedoara Ironworks was a significant mining and steel-making center, with a vast array of resources and output capacity. After 1920, it included iron ore mines at Ghelari, Arănieş, and Vadu Dobrii, as well as mining concessions at several other locations.

In the 1920s, engineers and economists pushed for increased output, with one plan calling for high growth by using the plant to its fullest capacity and refining cast iron to a higher degree. This led to the installation of upgraded equipment.

Between 1937 and 1940, a modern steel production and rolling section was built, featuring machinery imported from Nazi Germany. This new section covered 8500 square meters and included four special components.

The steel production and rolling section was equipped with four Siemens-Martin open-hearth furnaces, which could each fit 25 loads of tons, with a total capacity of 90,000 tons of steel ingots per year.

Hunedoara steel works have faced significant challenges over the years. Pollution was a major issue, especially before 1990, causing substantial air, water, and soil contamination.

The contamination is still evident today, with close to 140 ha of industrial land remaining contaminated. This is a stark reminder of the need for stricter environmental regulations.

High electricity prices have also taken a toll on the steel mill, with ArcelorMittal Hunedoara temporarily suspending its activities in 2025. This was a difficult decision made to reduce losses and protect employees.

The company has been working to mitigate the effects of pollution, taking steps to filter exhaust and treat wastewater since 2004.

The plant's thermal activity has been on the rise, with a significant increase in the Electric Arc Furnace (EAF_0) over recent months.

From November 2024 to April 2025, activity levels in EAF_0 rose steadily from 44.0% to 55.0%, reflecting increased operational efficiency and output.

This growth is a notable trend, with the overall change of +8.25% placing the plant within the orange alert range, highlighting a significant transition in operational dynamics.

The consistent growth in EAF_0 activity levels indicates a ramp-up in production capabilities, which is a positive development for the plant's overall performance.

Pollution has had a significant impact on Hunedoara, with metallurgical activity causing substantial air, water, and soil pollution before 1990.

Close to 140 hectares of industrial land that is now city property remains contaminated.

Fortunately, steps have been taken to mitigate this issue, with Mittal starting to filter exhaust and treat wastewater since 2004.

In 1991, the steel works became a state-owned joint-stock company, Siderurgica Hunedoara.

The following year, steel plant #1 was shut down, with a capacity of 330,000 tons of steel a year.

Steel plant #2 was gradually shut down in mid-1999, starting with the halt of sintering.

This was followed by the shutdown of coking and finally, on June 12, the cast iron-producing furnaces.

A further shutdown occurred in the spring of 2003, resulting in the layoff of 5300 workers.

The company was privatized in September 2003, becoming Mittal Steel Hunedoara.

It was later acquired by a subsidiary of the Mittal Steel Company in April 2004.

In 2006, the company took on the name of ArcelorMittal Hunedoara after the takeover of Arcelor by Mittal.

The administrative headquarters of the Hunedoara steel works, which once served as a school for workers, is a historic building in disrepair. It's a shame to see such a building fall into neglect.

The building's interior is a mess, with stray dogs roaming free and furniture wrecked by people searching for valuables. Documents and remaining furniture are scattered everywhere.

The stairs, cables, floors, and furniture were all stolen and sold by local Roma, highlighting the need for better security measures. This is a common problem in many abandoned buildings.

The attic is ravaged and home to a colony of bats, while the basement is cluttered with crates and hundreds of gas masks used by the Patriotic Guards to protect themselves from pollution. It's a testament to the plant's troubled past.

Here's a brief overview of the key issues with the administrative headquarters:

It's clear that the administrative headquarters requires significant restoration work to return it to its former glory.
