History of Stainless Steel

Background

The stainless steel was invented in the year 1900-1915. The collective hard work of many individuals, they begin to make stainless steel in 1821. Berthier who was a Frenchman found that the iron can be combined with chromium and is resistant to several acids. Other people studied the properties of chromium in an iron template and used a low proportion of chromium. About 10.5 percent chromium substance is used in order to make stainless steel.

M/s Woods and Clark found a British copyright which was recognized as a weather resistant alloy and an acid which contains about 1.5-2 percent of tungsten and about 30-35 percent chromium. Another Frenchman, Brustlein acknowledged the significance of carbon levels along with chromium in the year 1875. Stainless steel requires low level of carbon of about 0.15 percent. Other people examined the composition of iron or chromium and difficulty in acquiring the low carbon levels for several years and low carbon ferrochrome became less available.

Discovery

Leon Guillet printed research on alloys with masterpiece in the year 1904 which are called as 420, 442, 440-C. He also published a comprehensive revision of a nickel, iron and chromium alloy in 1906 which is considered as the main metallurgical constitution for the 300 sequence of stainless steel.

Giesen also published an extensive description on the nickel and chromium stainless steels in the year 1909. Portevin published various descriptions on an alloy in France and England . Borchers and Monnartz in 1908 also found facts of the connection between a low level of chromium, part of molybdenum in raising the corrosion resistance to chlorides and the low level of carbon content.

Industrial Development

Harry Brearley considered as a leader of the research department who runs a lab along with Thomas Firth and Sons and John Brown And Company and is usually recognized as the inventor of the manufacturing period of stainless steel. The first product made by him was table cutlery which is used till now for various applications.

Some of the industrial developments took place at the Krupp Iron Works situated in Germany . In this workshop, Frederick Becket and Dantsizen manufactured ferritic stainless and Benno Strauss and Eduard Maurer manufactured austenitic alloy. In 1908, Krupp developed a popular chrome and nickel steel hull which was examined by the Department of Archaeological Research of Florida.

Stainless steel manufacturers carry on their research on element composition, new progressing technologies, improvement in stainless steel making tools and lower costs and quality control.
