DIN 17102 WStE255 automobile structure steel plate

DIN 17102 WStE255 automobile structure steel

DIN 17102 WStE255 is a high-strength low-alloy structural steel used in applications such as automotive, heavy machinery, and building structures. It is produced by hot-rolled or cold-rolled processes and has good strength, toughness, and corrosion resistance.

Strength: DIN 17102 WStE255 has a tensile strength of 255 MPa and a yield strength of 225 MPa. This makes it an ideal choice for structural applications because it can withstand high loads.
Toughness: DIN 17102 WStE255 has an impact toughness of 30 J/cm2. This means that it can absorb a large amount of energy without breaking. This is important for structural applications because it helps to protect the structure from damage.
Corrosion resistance: DIN 17102 WStE255 has good corrosion resistance. This is due to its microalloying elements, such as vanadium and molybdenum. This is important for structural applications because it helps to extend the service life of the structure.

DIN 17102 WStE255 is primarily used in the following applications:

Automotive structures: Used for body structures, chassis structures, engine structures, suspension structures, and transmission system structures.
Heavy machinery: Used for frames, booms, and tracks.
Building structures: Used for beams, columns, and plates.
