EN10111 DD12 Automotive Steel

EN10111 DD12 Automotive Steel -1

IBC Metal Group manufacturer EN10111 DD12 automotive steel and export it to all over the world. This material is from the specification EN10111. The specification named “Continuously hot rolled low carbon steel sheet and strip for cold forming — Technical delivery conditions”.

It is a low carbon, hot rolled steel for cold forming. It is suitable for deep drawing and forming operations where it is not necessary to have mechanical properties. In the automotive industry, this steel is commonly used for body panels, brackets and reinforcements.

Scope of Specification EN10111

This European Standard specifies the grades of continuously hot rolled low carbon steel sheet and strip (in coils) for cold forming. Depending on its actual width, strip is classified as: hot rolled wide strip if its width is greater than or equal to 600 mm; and hot rolled slit wide strip if its width is less than 600 mm. For each grade, it specifies the chemical composition and the mechanical properties.

The specification is applicable to products of thickness not less than 1,0 mm and not exceeding 11mm. It is not applicable to products covered by other standards, such as: hot rolled products of non-alloy structural steels for general use (see EN 10025 all parts). And steel sheet for pressure purposes (see EN 10028 all parts); The steel sheet for welded gas cylinders (see EN 10120); And quenched and tempered steels (see EN 10083-1 and EN 10083-2).

Surface Characteristics

The sheets shall be free of slivers, blow holes, seams, cracks or scratches which would adversely affect their use. Pores, small pits, small marks, small scratches, kinks from pay-off reels and a slight coloration are permitted. The defects shall not be of such an extent that they might run the risk of causing failure or damage to tooling or welding difficulties when in use. The surface quality of the unwound coil is assessed as for sheets. However, the percentage of surface defects is generally greater than when supplied in sheets. The maximum percentage of permissible rejections shall be fixed by special agreement at the time of enquiry and order.

Mechanical Properties

It has good elongation and bending properties, making it suitable for deep drawing and forming operations. This steel is also easy to weld and has good surface quality. EN10111 DD12 steel plate/sheet is stamping and cold forming steels,it is suitable for non-structural press work and forming.It’s yield strength is between 170 to 320 MPa (there is different min strength point at the different thickness.) DD12 tensile strength is from around 420 MPa. (different min strength point at the different thickness.)

Chemical Composition

The chemical composition of EN10111 DD12 automotive steel includes carbon, manganese, phosphorus, sulfur and aluminum. The carbon content is kept low to ensure good weldability and formability. This steel also incorporates small amounts of manganese and aluminum to improve its strength and formability. Main chemical composition in EN10111 DD12 steel: Carbon max 0.10, Manganese max 0.45, Phosphorus max 0.035, Sulphur max 0.035, More detailed information,please refer to the flowing table:
