Cold-rolled micro-alloyed steel is part of our product portfolio and is suitable for cold forming. This product group includes the grades HC180Y/B, HC220Y/I/B, HC260Y/I/B/LA, HC300I/B/LA, HC340LA, HC380LA, HC420LA, HC460LA, and HC500LA. Micro-alloyed steel grades undergo grain refinement and precipitation hardening. The careful use of alloying elements ensures high mechanical strength and good weldability.

Carbon-Manganese Steel
Carbon-manganese steel combines high strength with exceptional formability, making it suitable for almost all demanding cold-forming applications.

High-Strength IF Steels (Y)
High-strength IF steels, like soft IF steels, have extremely low carbon content and are stabilized with titanium and/or niobium.

Bake-Hardening Steel
Bake-hardening steels achieve their strength in a special paint-baking oven used in the automotive industry. This process ensures good formability and enables the production of stronger final products.

Phosphorus-Alloyed Steel
These steels offer high mechanical resistance due to solid solution strengthening by phosphorus and are well-suited for cold forming. Phosphorus-alloyed steels are particularly used in the manufacturing of body panels and structural components due to their impact resistance and fatigue strength (removed in the latest revision of 2013).

Surface Type A:
Minor defects such as pores, small grooves, pimples, slight scratches, and slight discoloration (annealing stains, pickling marks) are permitted as long as they do not affect formability or the adhesion of surface coatings.

Surface Type B:
The prime surface must be nearly defect-free to ensure a uniform appearance after painting or electrolytic coating. The reverse side must meet at least the requirements of Surface Type A. The prime surface (Surface B) is agreed upon with the supplier at the time of ordering.

Surface Finishes
Upon request, the following surface finishes can be agreed upon:: „b“ – Extr Smooth; „g“ – Smooth; „m“ – matte ; „r“- rough
If no specific surface finish is indicated in the order, the matte finish will be supplied. These four finishes correspond to the mean roughness values in the following table and must be tested according to EN 10049.

Surface finish	Identification	Average surface finish (Limit length: 0,80mm)
Extra smooth	b	Ra ≤ 0,4 µm
Smooth	g	Ra ≤ 0,9 µm
Matt	m	0,60 µm ˂ Ra ≤ 1,9 µm
Rough	r	Ra ≤ 1,6 µm

These standards contain important additional information and specifications relevant to the correct application of DIN EN 10268. DIN ISO 10113 defines general delivery conditions for cold-rolled flat steel products. This standard includes provisions on dimensions, tolerances, surface quality, and marking. DIN ISO 10275 specifies testing procedures for cold-rolled flat steel products, including requirements for tensile strength, elongation, hardness, and weldability.
Familiarity with these standards is essential for all users of DIN EN 10268 to ensure that the steel products meet the required specifications.

Cold-rolled micro-alloyed steel according to DIN EN 10268 stands out due to its exceptional properties and offers numerous advantages for a wide range of applications. Whether in high-rise construction, civil engineering, mechanical engineering, vehicle manufacturing, or agricultural technology, this versatile steel impresses with its high strength, good formability, and excellent weldability.

Cold-rolled micro-alloyed steel according to DIN EN 10268 can also be electrolytically galvanized according to DIN EN 10152. This galvanization method provides additional corrosion protection, improving the durability and resistance of the steel. Electrolytic galvanization ensures a uniform zinc coating with excellent adhesion and even distribution on the steel surface. As a result, micro-alloyed steel becomes particularly resistant to environmental influences and is ideal for applications requiring high corrosion protection.
