The company extended its market to steam generators and started a rolling mill. During the 1930s, it produced armor for the army, torpedo tubes, cannon guns (Marine), propeller hubs (Aviation) and armor for tanks and armor plating for the Maginot line.

The 1980s were difficult. With the two oil shocks of 1973 and 1979, the group had financial difficulties. From 7,200 employees in 1975, its workforce dropped to 3,000 in 1985. The unit based at Denain will be sold in 1987
