Stainless steel needs to be protected to prevent damaging effects due to impurities. One of the most common ways to do this is with a process called passivation.
Steel is one of the most highly used metals in the modern world. Sky scrapers, tunnels, and bridges all use massive amounts of steel. Unfortunately, like many large industries, manufacturing creates high amounts of carbon dioxide, which contributes to air pollution and climate change.
In the 1800s, the United States began a revolution on the framework of the country. Bridges, buildings, piping, and transportation all became privy to the innovations of steel.
Stainless steel has been used in many forms over the last 150 years, but no industry can hold a candle to the impact it has had on the food and beverage industries.
