EN S355J0WP Weathering Corten Steel Sheet

S355J0WP is a designation for a structural steel grade according to the European standard EN 10025-5. The "S" in the designation stands for structural steel, while "355" indicates its minimum yield strength in megapascals (MPa). In this case, S355J0WP has a minimum yield strength of 355 MPa.

The letter "J" indicates that the steel has been impact-tested at 0 degrees Celsius. This property makes it suitable for use in low-temperature environments or applications where impact resistance is important.

The "0" in the designation signifies the minimum impact energy value required for the steel. In this case, it means that the steel has a minimum impact energy value of 27 Joules at 0 degrees Celsius.

The letter "W" refers to weathering steel, which is designed to have enhanced atmospheric corrosion resistance. It forms a protective oxide layer on its surface, which helps protect the steel from corrosion in various weather conditions.

The letter "P" denotes that the steel is intended for use in welded, bolted, or riveted structures.

Overall, S355J0WP is a weathering steel grade with good mechanical properties, including a high yield strength and impact resistance. It is commonly used in structural applications where resistance to atmospheric corrosion is required, such as bridges, buildings, and outdoor structures.
