PSA steel standards – Tailor-made materials for modern vehicle construction applications
The Peugeot Société Anonyme (PSA) Group, which includes renowned car brands such as Peugeot, Citroën, DS and Opel, includes tailor-made steel standards that are specially adapted to the requirements of the automotive industry. The PSA Group has developed its own standards to ensure optimum material properties in terms of formability, weldability and strength. All PSA steel standards listed below are available for your specific project. If you have any questions, please do not hesitate to contact us.
B53 3106 – Steel Flat Products Weldable Cold Rolled
The B53 3106 standard covers cold-rolled flat products that are characterized by excellent weldability and precisely finished surfaces.
These steels provide a reliable basis for applications in car body construction and other areas where uniform material properties and high process stability are required.
B53 3108 – Steel Flat Products Weldable Extra Mild
The B53 3108 standard describes extra mild, cold-rolled flat products, which are particularly impressive due to their excellent formability and weldability.
These mild steels are ideal for complex forming processes and are often used in applications where outstanding material softness is required without compromising on weldability.
B53 3312 – Steel Weldable Flat Products High Yield Strength LAF
The B53 3312 standard focuses on high-strength flat products that remain weldable at the same time.
These steel grades offer a high yield strength and are ideal for safety-relevant components that have to withstand high loads without impairing weldability.
B53 3316 – Hot Rolled Micro-Alloyed Steel Flat Products
The B53 3316 standard defines hot-rolled, micro-alloyed flat products that impress with their finely tuned alloy composition and outstanding mechanical properties.
These materials combine high strength with optimum processability and are particularly suitable for structurally stressed components in vehicle construction.
B53 3325 – Hot Rolled Ferrite Bainite Steel Flat Products
The B53 3325 standard covers hot-rolled flat products based on ferrite-bainite technology, offering an excellent balance between strength and toughness.
These steel grades are ideal for applications that require high strength combined with good formability and energy absorption.
With these extensive PSA steel standards, the PSA Group offers a wide range of high-quality materials that are individually tailored to the special requirements of modern vehicle construction projects. Our company provides you with these materials tailored to your project – we will be happy to provide you with further information and personal advice at any time.
