What Is Stainless Steel?

You’ve definitely heard about stainless steel, and you likely know that it is one of the best types of steel available, whether you are considering stainless steel kitchen appliances or stainless steel sheets, but what exactly is this coating? What makes it so special?

Stainless steel, also known as inox steel, is a steel alloy that has a minimum of 10.5% chromium content by mass. This content prevents the steel from corroding, rusting, or decaying in any other ways for many years. This steel is similar to carbon steel, but has a much higher chromium content, which prevents the rusting that is common when carbon steel is exposed to air.

Stainless steel has been in use for many years, with artifacts being found in India as early as 400 AD. These primitive stainless objects got their corrosion resistance from phosphorus content instead of chromium.

The first true iron-chromium alloys were found in France in 1821, and were created by the metallurgist Pierre Berthier. After some experimenting, Berthier noted high resistance to attacks by acids and air. A German metallurgist created a quicker process for creating stainless steel in the 1890s, and it was used more widely, starting in the first few decades of the 1900s.

Since then, stainless steel has been prevalent in many different industries and has been integral in strengthening products, including kitchen appliances, utensils, cabinets, backsplashes, BBQs, and much more.

For a coated iron alloy that won’t corrode, rust, or decay, stainless steel is the only option.
