S355K2C+N steel sheets are normalized structural steels manufactured in accordance with EN 10025-2. Combining a minimum yield strength of 355 MPa with enhanced impact toughness, they are designed for demanding structural applications requiring strength, reliability and long-term durability. In addition, the K2 impact requirement ensures excellent performance at low temperatures, while the C designation provides consistent material quality for industrial processing.
Sidastico supplies cut-to-size S355K2C+N steel sheets in a wide range of thicknesses and dimensions. Precision cutting improves dimensional accuracy, reduces material waste and simplifies fabrication. Every order is supplied with EN 10204 3.1 certification, guaranteeing full material traceability and compliance with European quality standards.
S355K2C+N steel sheets combine high mechanical strength with excellent weldability and good processing characteristics. They are suitable for laser cutting, plasma cutting, bending and conventional fabrication processes. When appropriate welding procedures are applied, this steel grade provides reliable performance even in demanding operating conditions. As a result, manufacturers can manufacture robust structures while maintaining efficient production processes.
Thanks to their combination of strength and toughness, this material is widely used for bridges, steel structures, industrial buildings, offshore components, heavy machinery and equipment operating under dynamic or low-temperature conditions. Furthermore, the excellent balance between mechanical properties and fabrication performance makes it a dependable choice for projects where safety and durability are essential.
With extensive stock availability and advanced steel processing capabilities, Sidastico delivers cut-to-size S355K2C+N steel sheets with short lead times, consistent quality and reliable service for demanding industrial applications.
