I was sitting around and wondering today what makes stainless steel stainless. So I thought I would look up the topic and write a quick article on it. Turns out, the big part of stainless steel is adding chromium to the outside of it. When you look at stainless stell, what you are really looking at is a coat of chromium with steel behind it. Because chromium is more precious and valuable than steel, the coating of chromium is only hundredths of an inch thick.
Many products today use stainless steel, including grills on the front of semi trucks, surgical instruments, handguns and valves, like this NBT stainless steel ball valve. Other famous things that have stainless steel on/in them are the Chrysler Building and the Gateway Arch in St. Louis.
