Cold rolled steel
Cold-rolled steel with high yield strength for cold forming
Standard of reference UNI-EN 10268
Non-alloy cold-rolled steels with a thickness of less than 3 mm, intended for forming or drawing, suitable for surface coatings (phosphating, painting, electrolytic coating, dip galvanising).
Materials used in applications that require resistance, stiffness and ductility and improved superficial aspects due to the treatments described above. Fields of application: automotive industry, furniture, white goods, heating and ventilation, pipes and section bars, etc.

STEELS FOR TRADITIONAL ENAMELLING
- DC01EK – DC04EK – DC06EK
- DC03ED – DC04ED – DC06ED titanium-alloyed decarbonised
STEELS FOR DIRECT ENAMELLING
- UNISMALT – SOLFER – SOLFER PLUS decarbonised open coil
- DC03ED – DC04ED – DC06ED decarbonised open coil
Before using the titanium alloyed decarbonised steels, it is essential to know the enamelling process in order to identify the most appropriate grade.
Cold-rolled steel for drawing and cold forming
Standard of reference UNI-EN 10268
High tensile steels with guaranteed minimum yield strength, which are excellent for welding and cold forming. Within this steel range, there are different grades depending on the final use, identified by the number that determines the minimum guaranteed yield strength.
The high mechanical characteristics and the good drawing grades allow to create cost-effective solutions for several parts or components requiring reduction in weight, thickness and overall dimensions, while leaving unchanged the resistance of parts or components.
Some examples of application can be: highway trailer trucks, buckets, large trucks, cranes, farm equipment, beams, welded tubes, profiles in general for scaffolds or shelves, containers, guide bars, street lamps. The regularity of spring back makes this steel suitable for all automated mass productions and also facilitates assembly.
