S355J2WP Weathering steel: widely used, good performance

concept

S355J2WP is a kind of European standard atmospheric corrosion resistant steel, which belongs to a kind of weather-resistant steel plate. It is a low-alloy steel made of a certain amount of alloying elements added to ordinary steel, and has excellent atmospheric corrosion resistance, which is 2 to 8 times that of ordinary carbon steel. At the same time, S355J2WP steel also has good mechanical properties and welding properties, and with the growth of time, its corrosion resistance effect is more and more obvious.

Mechanical property

S355J2WP steel plate is known for its excellent mechanical properties, mainly in the following aspects:

Yield strength: S355J2WP steel plate has a high yield strength, which means that it can maintain good stability and reliability when subjected to external forces. This characteristic enables S355J2WP steel plate to maintain its original shape and performance under heavy load and complex stress conditions.

Tensile strength: Tensile strength is an important index to measure the ability of steel plate material to resist tensile damage. S355J2WP steel plate has a high tensile strength, can withstand a large tensile force in the tensile process without breaking. This characteristic makes S355J2WP steel plate widely used in bridge, construction, ship and other fields.

Elongation: Elongation is an important index to measure the plastic deformation ability of steel plate materials during the tensile process. S355J2WP steel plate has good elongation and can produce large plastic deformation without fracture during the drawing process. This characteristic enables S355J2WP steel plate to maintain good toughness and reliability when bearing impact loads and dynamic loads.

Corrosion resistance: S355J2WP steel plate as a kind of atmospheric corrosion resistance steel, its corrosion resistance is particularly outstanding. It can maintain its original performance and appearance for a long time under harsh environmental conditions, such as humidity, salt spray and other environments.
