The History of Steel - ThoughtCo

Aug 21, 2020 · Blister steel production advanced in the 1740s when English clockmaker Benjamin Huntsman while trying to develop high-quality steel for his clock springs, found that the metal could be melted in clay crucibles and refined with a special flux to remove slag that the cementation process left behind. The result was a crucible, or cast, steel. The Various Types of Structural Steel ShapesApr 18, 2017 · Structural steel pipes are important for a variety of construction applications, lending strength and stability. Pipes are hollow, cylindrical tubes that come in a variety of sizes. Engineers often use steel pipes to meet the needs of water, oil, and gas industry projects. Tee.
