Watch the test of Docol HE

Watch the test of Docol HE

We decided to compare a conventional steel and Docol HE, both with the same strength. The difference between the two types of steel lies in the size and amount of perlite. Docol HE has a finer microstructure because the perlite is more finely distributed throughout the material. 

The test involves piercing the material 50% and 75% of the way through, followed by cutting 100% of the way through. When analyzing the samples in a microscope, we can see how the material flows and what the material can withstand. The results show that the conventional steel cracks, while Docol HE withstands even the most challenging tooth with a radius of 0.3 mm.

To summarize, the test confirms that Docol HE, with its outstanding edge ductility properties, is very well suited for fine blanking.
