DIN 1614 (EN10111) StW22 (DD11) Steel Sheet Coil

DIN 1614 is a German standard for flat products made of steel for cold forming. It has been replaced by the European standard EN 10111, which specifies the technical delivery conditions for hot-rolled products in the normalized or normalized rolled condition. StW22 (also known as DD11 in EN10111) is one of the grades covered by this standard. Here are some key features of DIN 1614 (EN10111) StW22 (DD11) steel sheet coil:

Chemical Composition

StW22 (DD11) steel has a specific chemical composition that includes elements such as carbon, manganese, phosphorus, and sulfur. The exact composition is defined in the EN10111 standard to ensure consistency and performance.

Mechanical Properties

StW22 (DD11) steel should meet specific mechanical properties, including yield strength, tensile strength, elongation, and other characteristics. These properties are essential for determining the material’s suitability for cold forming and other applications.

Hot-Rolled Process

StW22 (DD11) steel is typically produced through a hot-rolling process, where the steel slab is heated and then passed through rollers to achieve the desired thickness. This process imparts certain mechanical and structural properties to the steel.

Applications

StW22 (DD11) steel sheets and coils are commonly used in applications where cold forming is required. They find use in manufacturing various components, including automotive parts, appliances, and general structural components.

Surface Finish

StW22 (DD11) steel sheets and coils may have different surface finishes based on customer requirements. Common finishes include pickled and oiled or mill scale.

Standards and Certification

StW22 (DD11) conforms to the European standard EN 10111, which replaced the older DIN 1614 standard. It is essential to ensure compliance with the specified standard when procuring StW22 (DD11) steel to guarantee the material’s quality and suitability for the intended application.

Equivalent Grades

StW22 (DD11) may have equivalent grades in other international standards, such as ASTM or JIS. Identifying equivalent grades helps ensure that the material meets similar specifications across different standards.

When working with StW22 (DD11) steel sheets and coils, it is important to follow recommended processing and handling guidelines to maintain the material’s integrity and performance. Users should also consult the relevant standards and specifications to ensure proper application and compatibility with their specific requirements.
