Passivation (chemistry)
Videos
Passivation, in physical chemistry and engineering, refers to coating a material so it becomes "passive", that is, less readily affected or corroded by the environment. Passivation involves creation o
Tempering colors are produced when steel is heated and a thin film of iron oxide forms on the surface. The color indicates the temperature the steel reached, which made this one of the earliest practical uses of thin-film interference.

Stainless steel

Stainless steel is an iron-based alloy that contains chromium, making it resistant to rust and corrosion. Alternatively, it is known as inox, corrosion-resistant steel, Nirosta or rustless steel. Stai
Passivation (chemistry)
…oxidizing, historically known as bluing or browning. Ordinary steel forms a passivating layer in alkali environments, as reinforcing bar does in concrete. Stainless steels are corrosion-resistant, but they are not completely impervious to rusting. One common mode of corrosion in corrosion-resistant steels is when small…

Stainless steel is used for industrial equipment when it is important that the equipment is durable and easy to clean.
