What Does S355K2W Stand For?
S- symbols for structural steel.
355- indicates the minimum specified yield strength for thickness ≤ 16mm expressed in MPa.
The steel grades may be supplied in qualities J0, J2 and K2. the qualities differ in specified impact energy requirements.
W - indicates the steel has an improved atmospheric corrosion resistance.
Grade S355 is subdivided into the class W and WP, which differ mainly in their carbon and Phosphorus contents.
The material number of S355K2W steel is
1.8967. EN 10025-5 S355K2W steel products are supplied in plates, sheets, steel flats, bars, H beams. The ultrasonic testing of EN 10025-5 S355K2W steel plates shall be carried out in accordance with EN 10025-1.
S355K2W steel under EN 10025-5 standard is a kind of structural steel with improved atmospheric corrosion resistance steel. It is also called weathering steel or atmosphere corrosion resistance steel. Grade S355 is subdivided into the class W and WP: S355K2W and S355K2WP, which differ mainly in their carbon and Phosphorus contents.
This EN 10025-5 European Standard specifies requirements for flat and long products of hot rolled steels with improved atmospheric corrosion resistance in the grades and qualities given in chemical composition tables and mechanical properties tables in the usual delivery conditions.
