Deep-drawing Quality DC03 According to DIN EN 10152
The DIN EN 10152 standard specifies electrolytically galvanized, cold-rolled flat steel products for cold forming, including the deep-drawing grade DC03. This standard defines the requirements for the zinc coating and the basic mechanical properties of the base material.
DC03, when electrolytically galvanized in accordance with DIN EN 10152, is given an additional corrosion protection layer of zinc. This layer protects the material from oxidative influences and significantly increases the service life of the components made from it. The zinc coating can be applied in various thicknesses, depending on the specific requirements of the application. Typical coating thicknesses range from 5 to 20 µm.
The chemical composition and mechanical properties of the base material DC03 remain unchanged after galvanizing and meet the requirements of DIN EN 10130. DC03 therefore retains its excellent cold formability and mechanical performance. The yield strength, tensile strength and elongation at break also remain in the same range as for ungalvanized DC03.
The deep drawing grade DC03 is specified according to the standard DIN EN 10130, which focuses on cold-rolled flat products made of soft steels for cold forming. This standard defines the technical requirements and test methods for cold-rolled products used in various industrial applications, particularly where high demands are placed on surface quality and mechanical properties.
