The ultimate ironclad armor was case hardened nickel-steel. In 1890, the U.S. Navy tested steel armor hardened by the Harvey process and found it superior to compound armor. For several years 'Harvey steel' was the state of the art, produced in the U.S., France, Germany, Britain, Austria and Italy.
Redoutable was a central battery and barbette ship of the French Navy. She was the first warship in the world to use steel as the principal building material.

On February 28, 1890, BIW won its first contract for complete vessels: two iron gunboats for the Navy. One of these 190-foot (58 m) ships was the Machias, the first ship launched by the company. In 1892, the yard won its first commercial contract for the 2,500-ton steel passenger steamer City of Lowell. In the 1890s, the company built several ...
The shipyard was to consist of everything needed to fully complete a ship from a facility power plant to a wood joining shop. A steel plate mill and boiler shop were to be built as well. $10 million ($238 million today) was allocated for construction. The American Bridge Company was contracted to provide 10,000 tons of steel for the structures.
The materials that make up naval armour have evolved over time, beginning with simply wood, then softer metals like lead or bronze, to harder metals such as iron, and finally steel and composites. Iron armour saw wide use in the 1860s and 1870s, but steel armor began to take over because it was stronger, and thus less could be used.
