Galvanneal Steel Sheet

As a result some amount of powdering can appear when the metal is formed.

Galvanneal steel sheet.

Applications of galvanneal vary widely because many different types of steel can be galvannealed. Galvannealed sheet is carbon steel coated with zinc on both sides applied to the metal through a continuous hot dip process. For instance a thin low carbon steel may be galvannealed and made into a bracket on an automobile frame while a thick high strength low alloy steel may be galvannealed and used in the structure of a. However the zinc alloy coating on galvannealed sheet is more brittle than the zinc coating of galvanized sheet.

The steel is then annealed which converts the zinc into a zinc alloy coating that offers increased corrosion and scratch resistance. Galvannealed or galvanneal galvannealed steel is the result from the processes of galvanizing followed by annealing of sheet steel. Hot rolled galvannealed steel is derived from the temperature of the alloy when it is rolled into a sheet. Galvannealed steel is a matte uniform grey color which can be easily painted.

Hot rolled steel is steel that has been heated above its recrystalization point and is pushed between two rollers to meet a certain length and thickness. In comparison to galvanized steel the coating is harder and more brittle. Galvannealed sheet can be formed much in the same way and by the same variety of processes as galvanized sheet. Galvannealed steel is carbon steel coated with zinc using a hot dipped process.

This allows for the galvannealed steel to be more ductile and flexible. Common applications of galvannealed steel.
