There are detailed differences between DX51D galvanized steel sheet and DX56D galvanized steel sheet in many aspects. The following are their main differences:
Steel grade serial number:
DX51D galvanized steel sheet is a bending and forming grade galvanized steel sheet with a steel grade serial number of 51.
DX56D galvanized steel sheet has a higher steel grade serial number of 56, which generally indicates that it has higher hardness and strength.
Thickness and hardness:
DX51D galvanized steel plate generally has a thickness of 0.2-1.5 mm and a hardness of mild steel.
DX56D galvanized steel plate generally has a thickness of 0.3-3.0 mm and a hardness of semi-hard steel or hard steel.
Use and performance:
DX51D galvanized steel sheet is mainly used for cold forming and deep forming, such as the production of home appliances and automotive parts, because it has excellent machinability, mechanical properties and appearance properties, as well as excellent corrosion resistance.
DX56D galvanized steel sheet is commonly used in the automotive, construction, shipbuilding and other industries due to its higher hardness and thicker thickness. It is suitable for the production of cold-rolled profiles, deep-formed parts and containers.
Galvanized layer:
Both are galvanized steel sheets, but the galvanized layer may vary depending on the application scenario and needs. For example, DX56D galvanized steel sheet can have a variety of different galvanized layer types and weights, such as 60g, 80g, 100g, etc.
