Understanding DIN 1624: The Standard for Cold Reduced Mild Unalloyed Steel Strip
DIN 1624 is a retired German quality standard developed by the Deutsches Institut für Normung (DIN) that specifies technical delivery conditions for cold reduced mild unalloyed steel strip
. It primarily covers steel strips in widths not exceeding 650 mm. Scope and Technical Specifications
The standard outlines the requirements for steel grades intended for forming and surface refinement. Key technical highlights include: Steel Grades : A prominent grade mentioned under this standard is
, which represents a deep-drawing quality steel suitable for producing thin sheets in strips up to 3 mm thick. Surface Types
: DIN 1624 categorizes surface finishes into several grades, such as: : Darkly annealed. : Glossy annealed. : Surface without fissures and pores. : Glossy overglazed. Dimensions
: Dimensional tolerances and limits for products under this standard are typically governed by Mechanical Properties : It details properties like tensile strength ( cap R sub m ) and elongation ( ), often comparing grades like (skin passed) and (annealed).

It is important for engineers and procurement specialists to note that DIN 1624 has been withdrawn
. While it was once the go-to German standard, it has been superseded by European standards to unify technical specifications across the EU. The primary modern equivalent is DIN EN 10139 Applications and Characteristics
Cold rolled strips conforming to this standard are favored for applications requiring close dimensional tolerances and specific surface finishes. Chesterfield Steel DIN 1624 - 1977-07
The DIN 1624 standard specifies requirements for mild unalloyed steel strip that is cold rolled. This steel is typically used for applications requiring good forming properties, such as drawing or bending, and is often supplied in coils or cut lengths. Key details regarding the standard: Mild unalloyed steel strip (cold rolled). Application: din 1624 standard pdf
General engineering, automotive parts, and deep-drawing components. Key Properties:
Defined chemical composition, mechanical properties (yield strength, tensile strength), and surface finish quality. To obtain the DIN 1624 standard PDF

Note: Searching for free PDFs often leads to outdated documents or illegal copies. Always use official sources to ensure compliance with the current standard revision.
If you need an authentic copy of the DIN 1624 standard PDF, you must be careful. While free PDFs may circulate on some engineering file-sharing sites, these are often low-quality scans of outdated, non-binding copies. For professional use, you need a verified document.
DIN 1624 remains an important historical reference for cold-rolled mild steel strips. While it has been superseded by DIN EN 10139, the document is still essential for reverse engineering and maintaining legacy equipment. Professionals seeking the PDF should prioritize obtaining it from official sources like Beuth Verlag to ensure accuracy and legal compliance.
The DIN 1624 standard primarily defines the specifications for four-prong tee nuts used extensively in woodworking and furniture assembly. While it originally covered cold-rolled mild steel strip technical delivery conditions, it is now most commonly associated with these specialized fasteners. Overview of DIN 1624 Tee Nuts
These nuts feature a flat flange with four integrated prongs (claws) that bite into wood or composite materials to prevent the nut from spinning during bolt installation.
Materials: Typically manufactured from galvanized carbon steel for corrosion resistance or stainless steel (A2/A4) for high-moisture environments.
Applications: Ideal for furniture (sofas, chairs, cabinetry), rock climbing holds, and any timber frame construction requiring a flush-mounted internal thread. Understanding DIN 1624: The Standard for Cold Reduced
Installation: Involves drilling a pilot hole and hammering or pressing the nut into the material until the flange is flush with the surface. Common Dimensions & Specifications

The DIN 1624 standard, titled "Steel flat products; cold reduced mild unalloyed steel strip in widths not exceeding 650 mm; technical delivery conditions," is a technical specification for unalloyed steel strip. While the original DIN 1624 standard has been withdrawn and replaced by DIN EN 10139, it remains a frequent reference in engineering and fastener manufacturing. Overview of DIN 1624
This standard defines the quality requirements and delivery conditions for cold-rolled steel strips. These products are typically used for mechanical treatment and surface refinement, such as electroplating or painting.
Scope: Applies to cold-reduced flat products (strip and cut lengths) in widths up to 650 mm and thicknesses up to 6 mm. Material: Specifically covers soft, mild unalloyed steels.
Suitability: These steels are suitable for forming and surface refinement but are not intended for quench hardening or tempering. Common Applications
The keyword "DIN 1624 standard pdf" is often searched for in two distinct contexts:
Fastener Specifications (Tee Nuts): In the hardware industry, DIN 1624 refers to pronged tee nuts used in furniture. These nuts are designed to be driven into wood, with prongs providing a strong grip to prevent rotation. Specifications often include diameters from M4 to M12 and varying heights from 6 mm to 15 mm.
Steel Manufacturing: As a quality standard, it guides the production of cold-rolled strip used in automotive components, industrial machinery, and stamped parts. Technical Specifications for Steel Strip How to Find and Download a Legitimate DIN

First, a critical clarification:
DIN 1624 is a withdrawn German standard. It was titled “Steel grades with specific magnetic properties – Technical delivery conditions for flat products made of magnetic steel” (roughly: Magnetic steel strip for electrical and electromechanical devices).
It has been superseded by European (EN) and international standards, primarily DIN EN 10106 and DIN EN 10107 (grain-oriented electrical steels) and DIN EN 10165 for magnetic properties measurement.
If your paper is historical or technical, you should note that the PDF you seek is no longer maintained by Beuth Verlag (German standards body), but copies may exist in old technical libraries.
Historically, the DIN 1624 PDF document was concise and technical. A typical PDF contains:
Companies that have been in operation for several decades often maintain internal "Standards Libraries." If you work in manufacturing, checking the engineering department's shared drive or physical archives is often the fastest way to locate a PDF of DIN 1624.
The standard mandated that the wire be free from scale, cracks, and seams. It required torsion tests (minimum number of twists before fracture) and bend tests for smaller diameters.
In the world of mechanical engineering and precision manufacturing, standards are the silent guardians of quality. Among the dozens of materials standards used daily in German and European industry, DIN 1624 holds a specific, vital niche. If you have searched for the term "DIN 1624 standard PDF" , you are likely involved in the production of springs, wire forms, or tension-loaded components. You need the technical specifications, chemical compositions, and mechanical properties of unalloyed steel wire.
However, there is a critical piece of information that many online searches fail to reveal: DIN 1624 is a withdrawn standard. This article serves two purposes. First, it provides the core technical data you would have found in the original DIN 1624. Second, it guides you to legitimate sources for historical PDF documentation and explains which active standards have replaced it.
A: Yes, if your contract or product specification explicitly references it. However, for new designs, you should always use the current EN or ISO replacement. If you use a withdrawn standard, you assume all liability for safety and performance.
