hot-dip galvanized steel DX52D
The hot-dip galvanized steel DX52D in accordance with standard 10346 is an essential material in modern manufacturing processes. With the material number 1.0918 (formerly 1.0350), this steel offers an excellent combination of optimum cold forming properties and increased resistance to corrosion. The classification as a drawing grade underlines its particular suitability for demanding cold forming processes where a precise balance between formability and mechanical strength is required.
As part of the galvanizing process, a protective zinc coating is applied to the steel surface to provide the material with lasting protection against environmental influences. In addition to the standard +Z coating, users can choose from other specific coatings such as +ZF, +ZA, +ZM, +AZ and +AS. These variations allow the steel to be precisely matched to the respective application conditions. Depending on the coating variant selected, the surface roughness can be optimized or additional protection against chemical attack can be guaranteed, for example, making DX52D steel an extremely flexible material for industrial applications.

The appearance of the coating is bright, meticulous, without sagging or wrinkles. Thickness inspection can use coating thickness gauge, the method is relatively simple. The thickness of the coating can also be obtained by converting the amount of zinc adhesion. For the bonding strength, a bending press can be used to bend the sample at 90-180°, and there should be no cracks or peeling of the coating. A heavy hammer can also be used to test, and the salt spray test and copper sulfate corrosion test can be done in batches.
