Overview
EN 10111:2008 is a European Standard developed by CEN that specifies the technical delivery conditions for continuously hot rolled low carbon steel sheet and strip intended for cold forming. It covers grades of steel sheet and strip supplied in coils, classifying strips based on width-either as hot rolled wide strip (≥ 600 mm) or hot rolled slit wide strip (< 600 mm). Applicable to thicknesses from 1.0 mm up to 11 mm, this standard defines key requirements such as chemical composition, mechanical properties, surface conditions, and testing protocols to ensure consistent quality and performance tailored for cold forming processes.
This standard is essential for manufacturers, fabricators, and purchasers engaged in steel product supply chains for cold forming applications, providing clear guidelines for product classification, production methods, and quality criteria to ensure reliable and uniform steel products for industrial use.
Key Topics
Steel Grades and Classification
EN 10111:2008 classifies low carbon steel products into four grades (DD11, DD12, DD13, DD14), each grade defined by specific limits on chemical composition and mechanical properties. These grades offer increasing formability from DD11 to DD14, allowing users to select steel based on their cold forming requirements.Chemical Composition and Mechanical Properties
The standard sets maximum limits for elements including carbon, manganese, phosphorus, and sulfur. Mechanical properties such as tensile strength, yield strength, and elongation are specified to meet performance expectations for cold forming.Manufacturing Process and Deoxidation
Steelmaking and finishing processes are typically at the manufacturer's discretion; however, full killing (complete deoxidation) is mandatory for grades DD12 through DD14 to improve quality and consistency.Surface Characteristics and Delivery Conditions
Products are generally delivered as rolled with scale or descaled and oiled surfaces. Surface quality requirements address defects like cracks or slivers that could impair forming or welding. Oiling methods protect steel surfaces from corrosion during storage and transport.Weldability and Suitability for Coating
The steels covered are suitable for standard welding techniques. They can also be prepared for metallic coatings such as hot-dip galvanizing, making them versatile for various finishing processes.Testing and Inspection
Detailed testing methods including tensile testing, chemical analysis, and surface inspections ensure compliance with the standard. Inspection units and sampling procedures are clearly defined to maintain product integrity.
Applications
EN 10111:2008 steel products are widely used in cold forming processes such as:
- Automotive Industry: Manufacturing body panels, structural components, and chassis parts that require formability and surface quality suitable for painting or coating.
- Appliance Manufacturing: Production of enclosures and structural parts that demand consistent mechanical properties and surface finishes.
- Construction and Building: Fabrication of elements like metal cladding, roofing, and framing components requiring cold-formed steel sheets and strips.
- General Fabrication: Any application where low carbon steel strips or sheets are cold formed into intricate shapes, relying on precise mechanical and chemical requirements.
These steels support versatility in forming operations including bending, drawing, and stamping, beneficial for industries seeking high-quality, reproducible steel products.
Related Standards
EN 10111:2008 should be considered alongside several complementary standards to cover different steel products and purposes:
- EN 10025 (all parts) - Hot rolled non-alloy structural steel products for general use.
- EN 10028 (all parts) - Steel sheets for pressure purposes.
