"Perhaps the idea of producing on a commercial scale a steel which would not corrode sounds ridiculous, at least my directors failed to grasp the significance of it." -Harry Brearly

In 1912 Brearley encountered two problems common of many small arms manufacturers in which the internal diameter of the rifle barrels were dissolving away too quickly due to the heating and discharge of the bullet. Brearly then decided to find a steel that better resisted to erosion. In his experiments, he combined steel with chromium because chromium was known to have a higher melting point than ordinary metals. The first true stainless steel was melted on August 19th, 1913. Initially, Brearly called his invention "rustless steel," composed of 12.8% chromium and 0.24% carbon. He noted its resistance to corrosion and acid decay.
In Brearley's time, sharp cutting utensils were silver or nickel plated and would usually be susceptible to rust. Brearley was able to conclude that his new steel would help the kitchen cutlery industry, but he had trouble convincing the heads of the cutlery industry that his invention was truly effective.
