S355J0WP steel plate tensile strength and yield strength

Application of S355J0WP steel plate: S355J0WP steel plate is used for bridges, ships, power station equipment, hoisting and transportation machinery, machinery manufacturing and other engineering and welded structural parts bearing high loads.

Tensile strength of S355J0WP steel plate（ σ b/MPa）
＞ 3 - ≤ 16mm (thickness) 470-630
＞ 16 - ≤ 40mm (thickness) 470-630
＞ 40 - ≤ 63mm (thickness) 470-630
＞ 63 - ≤ 80mm (thickness) 470-630

Yield strength of S355J0WP steel plate（ σ s/MPa）
＞ 3 - ≤ 16mm (thickness) ≥ 355
＞ 16 - ≤ 40mm (thickness) ≥ 345
＞ 40 - ≤ 63mm (thickness) ≥ 335
＞ 63 - ≤ 80mm (thickness) ≥ 325

S355J0WP steel plate improved atmospheric corrosion resistant steel adds a certain amount of alloy elements, such as P, Cu, Cr, Ni and Mo, to the steel. In order to increase the resistance to air corrosion, an automatic protective oxide is generated on the base metal under the influence of climatic conditions.
