High-grade Steel

High-grade Steel is a product manufactured in a Steelworks. Precious Metals is the material required to make it. It can be used as material for other products.
==History==
Stainless steel was first developed in 1913. As early as 1820, the French metallurgist L. Berthier discovered that fluoric steel grew non-corroding if he mixed it with alloy additives like chromium. In 1913 British scientists alloyed pure chromium with a variation on Berthier´s carbon steel. This resulted in a metal which did not lose its shine and which genuinely deserved to be called 'stainless'. A year later, Krupp released a new type of 'high-grade steel' containing chromium and nickel on the market. In 1921, the Meridan Silver Company produced the first cutlery made from high-grade steel.
==Did You Know That?==
Stainless rustproof steel has been one of mankind´s dreams for ages. It is simply amazing what you can make with it! Scientists first succeeded in creating stainless steel at the start of the 20th century. Since then, the metal has revolutionised homes, hotels, restaurants and, last but not least, the music industry. Traditional metals, such as iron and silver, no longer serve the common need. The current generation buys cutlery made of high-grade steel.
