Stainless steel has been around for many years. Harry Brearley of England is credited as being the inventor of stainless steel in 1912 when he was working on an erosion-resistant alloy for gun barrels. Today, stainless steel is a vital part of our modern world.
Stainless steel is a metal composed of iron alloy and a minimum of 10.5% of chromium. The chromium makes the metal resistant to staining, corroding, and oxidation. Stainless steel comes in many grades that determine the application of the metal. This is a relatively hard, durable, and affordable metal, which typically comes in light gray.
