Hot-dip galvanization is a form of galvanization.It is the process of coating iron and steel with zinc, which alloys with the surface of the base metal when immersing the metal in a bath of molten zinc at a temperature of around 450 °C (842 °F). When exposed to the atmosphere, the pure zinc (Zn) reacts with oxygen (O 2) to form zinc oxide (), which further reacts with carbon dioxide (CO 2 ...

The initial steel shapes—blooms, billets, slabs, etc.—are hot rolled into bar, wire, sheet, strip, and plate. Depending on the form, the steel then undergoes further rolling steps (both hot and cold rolling), heat treatment (annealing), descaling Ito remove buildup), and polishing to produce the finished stainless steel.

Stainless Steel - Lenntech. Stainless steel is a group of iron-based metal containing at least 10% chromium (alloy metals). The chromium oxide "CrO" creates an invisible barrier ("passive film") to oxygen and moisture. Therefore the Chromium protects the iron against most corrosion or red-colored rust; thus the term "stainless" steel.
