S355J2WP steel plate is a kind of steel that enhances its atmospheric corrosion resistance by adding alloying elements to ordinary steel. This steel plate has excellent corrosion resistance, and its atmospheric corrosion resistance is 2 to 8 times that of ordinary carbon steel.
S355J2WP steel plate features:
Corrosion resistance: S355J2WP steel plate can show good corrosion resistance in a variety of corrosive environments, including acids, alkali, salt and other chemicals as well as corrosive media in the atmosphere and soil.
Mechanical properties: The steel plate has high strength and hardness, and has good plasticity and toughness, and can show good resistance to withstand various complex stresses.
Welding and molding performance: S355J2WP steel plate has good welding performance and molding performance, can meet a variety of processing and production needs.
Fatigue resistance and impact resistance: This steel plate also has good fatigue resistance and impact resistance, which helps to improve the quality and reliability of the product.
The chemical composition of S355J2WP steel plate includes carbon (C), silicon (Si), manganese (Mn), phosphorus (P), sulfur (S), chromium (Cr) and copper (Cu) and other elements. Among them, the carbon content does not exceed 0.15%, the silicon content does not exceed 0.80%, the manganese content does not exceed 1.1%, the phosphorus content is between 0.05% and 0.16%, the sulfur content is not more than 0.035%, the chromium content is between 0.25% and 1.35%, and the copper content is between 0.2% and 0.6%.
The mechanical properties of S355J2WP steel plate include yield strength, tensile strength, elongation and impact toughness. According to EN 10025-5 standard, the yield strength of the steel plate is not less than 355MPa, and the tensile strength is between 470 and 630MPa. At the same time, the steel plate also has good elongation and impact toughness, which can meet the requirements of use under various complex stress states.
S355J2WP steel plate application:
