StW22 steel, also known by the abbreviation DD11, is a type of steel with a well-defined chemical composition that includes elements such as carbon, manganese, phosphorus and sulphur. These components are regulated by the EN 10111 standard, which sets limits to ensure uniformity in the quality and performance of the material.
In terms of mechanical properties, this steel must meet certain requirements, such as yield strength, tensile strength and elongation before breaking. These properties are essential for assessing whether the material is suitable for cold working or other manufacturing processes.
Production generally involves hot rolling. In this process, the semi-finished steel, called slab, is heated to high temperatures and then compressed through a series of rollers until it reaches the desired thickness. This treatment gives the steel specific structural and mechanical characteristics.
Thanks to its versatility, this steel is widely used in various industries: it is used to manufacture components in the automotive sector, parts for household appliances and other structural elements for general use.
