The hot-dip coated deep-drawing steels of the DX grade family according to EN 10346 offer excellent forming properties and good aging resistance. The mechanical properties of the individual deep-drawing steel grades are characterized by the level of yield strength and tensile strength as well as by assured minimum values of elongation at break.

Low-carbon steel for cold forming

Properties according to EN 10 346

 

DX51D | 1.0917

 

 

Grade DX51D is a machine folding grade and is suitable for simple craft forming work as well as for the production of simple profile shapes. DX51D is generally applicable in mechanical and structural engineering, e.g. for ventilation technology, air conditioning systems, switch cabinets, electrical industry, household appliances and steel furniture.
