I think the Linz-Donawitz steelmaking process does not get enough credit sometimes for how much it changed steelmaking > It reduced capital cost of the plants and smelting time, and increased labor productivity. Between 1920 and 2000, labor requirements in the industry decreased by a factor of 1,000, from more than three man-hours per metric ton to just 0.003.
