Breakthrough In Stainless Steel In Germany
Iron’s main drawback and an industrial metal is its tendency to corrode. Many alloys, a mixture of two or more metals attempted to solve this problem. The corrosion resistance of iron-chromium alloys was first recognized in 1821 by French metallurgist Pierre Berthier. In the late 1890s a process for producing carbon-free chromium was developed in Germany and between 1904 and 1911 several researchers prepared alloys that would today be considered stainless steel.
