Chromium is element number 24 on the Periodic Table and is represented by the symbol Cr.
It is commonly used in electroplating, primers, together with nickel for superalloys in jet engines and gas turbines, and more importantly, as we are all keenly interested in, to manufacture stainless steel.The use of Chromium in stainless steel is two fold: for its corrosion resistance properties and to increase strength in steel due to the formation of Chromium carbides, which are in fact, the hardest carbides so far. Who knows into the future?
What does this mean for the knife maker? We are able to craft a blade is that far less susceptible to rust, and although even stainless steel can rust, it is going to be far less pitted than an average high carbon steel. See also the Frequently Asked Question: Can stainless steel rust? It also means that the edge your knife takes is going to be superior and will not be as affected by acids, e.g. orange juice, when used to cut acidic foods. It will also stay sharper a little longer.
In fact, Chromium is what makes stainless steel stainless.
Precautions:
Chromium dust can be extremely harmful due to oxidational properties, resulting in damage to the kidneys, liver and blood cells. It is also carcinogenic.
