What Is Stainless Steel? And How Do They Grad It?
Steel is an iron-carbon alloy with a maximum carbon concentration of 2.1 percent. Stainless steels are a type of steel that has had some alloying added to make them resistant to corrosion. The term stainless steel is a grouping of about 200 steel alloys that are extremely resistant to corrosion and heat. The carbon content could vary between 0.03 percent and 1.2 percent. Its unique feature is the high chromium level. Stainless-steel cookware contains a minimum of 10.5 percent chromium, which enhances resistance to corrosion. Exposure to the air creates an inactive layer that prevents oxidation. This inactive coating protects the alloy from further corrosion and renders it rustproof. This allowed the alloy to maintain its flawless appearance for extended periods of time, while still meeting all requirements. Stainless steel has been used successfully across many industries for more than 70 years. As stainless ...
