S355J0WP steel is a kind of European standard atmospheric corrosion resistant steel, also known as weathering steel. It is a low-alloy steel made on the basis of ordinary steel by adding a small amount of alloying elements (such as copper, nickel, etc.). This steel has good atmospheric corrosion resistance, and its weather resistance is 2 to 8 times that of ordinary carbon steel, and its coating property is 1.5 to 10 times that of ordinary carbon steel.
S355J0WP steel features:
S355J0WP steel not only has the strength, plastic casting, forming, welding and cutting, abrasion, high temperature, fatigue resistance and other characteristics of high-quality steel, but also has excellent weather resistance.
This steel plate can still maintain stable performance under harsh climatic conditions and is not susceptible to corrosion and oxidation.
At the same time, S355J0WP steel also has the characteristics of rust resistance, which can make the component corrosion-resistant and prolong life, reduce thinning and consumption, save labor and energy.
The chemical composition of S355J0WP steel mainly includes carbon (≤0.12%), manganese (≤1.60%), phosphorus (≤0.025%), sulfur (≤0.020%), silicon (≤0.50%) and copper (≤0.55%).
The tensile strength of S355J0WP steel varies according to the thickness, but it is generally between 470 and 630 MPa. The yield strength also decreased slightly with the increase of thickness, but the lowest value was still above 325 MPa. In terms of impact work Akv of 0°, S355J0WP steel also performs quite well, with a value greater than or equal to 27J.
S355J0WP steel application:
S355J0WP steel has a wide range of application prospects in construction, bridge, vehicle and other fields.
It is mainly used in railway, vehicles, Bridges, towers and other long-term exposure to the atmosphere of the use of steel structures.
At the same time, S355J0WP steel is also used in the manufacture of containers, oil RIGS, port buildings, oil platforms and containers containing hydrogen sulfide corrosive media in chemical petroleum equipment and other structural parts.
In general, S355J0WP steel with its excellent weather resistance and mechanical properties, in the construction, Bridges, vehicles and other fields to show a broad application prospects.
