Stainless steel is an alloy of various metals such as steel, chromium, nickel, copper, and others. The quality and features of a stainless steel pot or pan is dependent on the degree of other metals used in its making process.
The exact composition of steel and other metals can determine temperature resistance, quality, durability, and more. For example, higher concentrations of aluminum or copper may improve heat conductivity. Chromium helps in enhancing the durability, whereas nickel provides it with corrosion protection. Ultimately, each element serves a general purpose but stainless steel is mostly popular for its anti-corrosive properties and high strength.
