Creusot-Loire was a French engineering conglomerate, formed from factories in Le Creusot and Châteauneuf, Loire.[1] The Creusot-Loire subsidiary of ArcelorMittal also includes an Innovation, Research and Development centre for the group.[2]
The enterprise developed what has become known as the Creusot-Loire Uddeholm (CLU) converter process, which was developed to minimize the need of argon, and which was first erected on an industrial scale in the 1970s at Degerfors.[5]
In 1984 the organisation became bankrupt with debts of $633 million;[7] the company's owner Empain-Schneider rejected state aid as the conditions included giving away control of another subsidiary Jeumont Industrie.[6]
At some point near 2000, Imphy SA owned the Invar trademark.[8]
At some point, the organization may have been part of Usinor, which became in the 2001/2 restructuring the company known as Arcelor.
Before September 2003, the organisation had been renamed Industeel and absorbed by Arcelor.[9][10]
In September 2015, Industeel was touting its homogeneous armour products and its ballistic protection steel plates. It boasted that 5mm of its MARS 600 product could stop a NATO 7.62mm round at a distance of 10m.[11]
