Cold rolled microalloyed steel

Cold rolled microalloyed steel is among other things part of our product portfolio, which is suitable for cold forming. This product group is assigned with the grades HC180Y/B, HC220Y/I/B, HC260Y/I/B/LA, HC300I/B/LA, HC340LA, HC380LA, HC420LA, HC460LA and HC500LA. Microalloyed steel grades undergo grain refining and precipitation hardening. The careful use of the alloy materials ensures high mechanical strength and good weldability.

Carbon-manganese steel

The carbon manganese steel combines high strength with outstanding formability for almost all difficult cold forming applications.

High strength IF steels (Y)

High-strength IF steels, like the soft IF steels, have extremely low carbon contents and are stabilized by titanium and/or niobium.

Bake hardening steel

Bake-hardening steels reach their strength in a special painting furnace for the automotive industry. The product is therefore also easy to shape and allows firmer end products.

Phosphor-alloyed steel

These steels offer high mechanical resistance due to solid solution hardening by phosphorus and are ideal for cold forming. The phosphorus-alloyed steel grades are particularly used in the manufacture of body panels and structural components as they are shock-resistant and fatigue-resistant (have been deleted with the latest revision (2013)).

Surface type

Surface A

Mistakes such as pores, small grooves, small warts, slight scratches and a slight discoloration that does not affect the ability to reshape and adhere to surface coatings are permitted.

Surface B

The better side must be free from defects so that the homogeneous appearance of a quality finish or an electrolytically applied coating is not impaired. The other side must at least meet the requirements of surface type A.

Surface finish

The surface finish may be particularly smooth, dull or rough. If no details are given when ordering, the surface finish will be delivered in a matt finish. The four surface finishes listed correspond to the center roughness values in the following table and must be tested in accordance with EN 10049.
