Galvanised Mild Steel Properties

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.

Galvanised mild steel properties.

The key difference between mild steel and galvanized iron is that the mild steel undergoes rusting very easily if the steel has no proper coating whereas galvanized iron has corrosion protection. Unlike high carbon steel mild steel is easily welded. Mild steel is a form of carbon steel that is an alloy of iron and carbon along with some trace elements. The properties of galvanized steel are a unique combination that make it ideal for use in interior and exterior applications such as car bodies appliances nuts and bolts roofs and rebar.

In developed countries most larger cities have several galvanizing factories and many items of steel manufacture are galvanized for protection. 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 449 c 840 f. Typically with galvanized steels the zinc coating suppresses the potential of the mild steel at coating breaches and therefore prevents the steel substrate from corroding until a significant fraction of the zinc coating is consumed figure 1 13. Some types of high carbon steel such as stainless steel require special techniques in order to properly weld the material.

This is the most common use for galvanized metal and hundreds of thousands of tons of steel products are galvanized annually worldwide. The properties of the steel allow the electrical current to travel through the metal without distorting the makeup of the material.
