Stainless steelIn 1820, as the steel industry was making huge technological advances, chemists tried to create a rust-proof, or stainless steel. A French metallurgist observed that when carbon steel was combined with an alloy like chrome, it did yield a rust-resistant metal. A century would pass before two British scientists continued his work and, in 1913, Europe was introduced to stainless steel. Its smooth, hard surface doesn't trap dirt, bacteria or molds - and today, stainless steel is used in everything from silverware and jewelry to spacecraft. |
