Docol Roll 800
Cold-rolled, high-strength steel for roll forming
Docol Roll 800 is characterized by both a high yield strength and an improved cleanliness, which allows for a tight radius.
In deep drawing, the material should have a low yield strength to tensile strength ratio. In roll forming, however, you benefit from using a material with a high yield strength in order to avoid unwanted longitudinal plastic strains in the product.
