Weathering steel S355J0WP

Weathering steel S355J0WP Features:

S355J0WP is an alloy structural steel with excellent atmospheric corrosion resistance. Its main features include:

Weather resistance: Through special smelting and rolling process, a dense protective film with strong adhesion is formed on the steel surface, which significantly improves the corrosion resistance of steel in harsh atmospheric environment.

Excellent mechanical properties: high strength, high toughness, good weldability and machinability. The yield strength is not less than 355MPa, the tensile strength is between 470-630MPa, and it has good impact toughness and cold bending performance.

Excellent plastic indicators: excellent performance of plastic indicators such as elongation and section shrinkage, which can meet the manufacturing needs of various complex structures.

Delivery status of Weathering steel S355J0W

The delivery status of S355J0WP steel mainly includes hot rolling and normalizing + tempering two kinds:

Hot rolling delivery status: Hot rolling is a common process in steel production that involves rolling billets to the desired size and shape at high temperatures. Hot rolled steel has the advantages of good surface quality, high dimensional accuracy and stable performance. When S355J0WP steel is delivered in the hot rolled state, its surface will show a certain oxide, but after subsequent processing, these oxide can be removed, and will not affect the performance of the steel.

Normalizing + tempering delivery state: Normalizing is the heat treatment process that heats the steel above the critical temperature and holds it for a certain time in free air. Normalizing can eliminate the residual stress in steel and improve the cutting performance of steel. Tempering is the heat treatment process of heating steel to a certain temperature, holding it for a period of time, and then cooling it to room temperature. Tempering can reduce the hardness and brittleness of steel and improve the toughness and plasticity of steel. When S355J0WP steel is delivered in the normalizing + tempering state, its organization is more uniform and its performance is more stable, which is suitable for occasions with higher requirements for steel properties.

Application range of weathering steel S355J0W

Because of its unique corrosion resistance and mechanical properties, S355J0WP steel has been widely used in construction, bridge, vehicle manufacturing and Marine engineering and other fields:

Construction field: It is used to manufacture various outdoor facilities, steel structures and Bridges to cope with the challenges of harsh climate and environment.

Bridge construction: Due to its high strength and corrosion resistance, it is suitable for bridge beams, support structures and guardrails, providing stable structure and good durability.

Vehicle manufacturing: It is used to manufacture key components such as body frames and chassis to improve the durability and safety of vehicles.

Marine engineering: plays an important role in key facilities such as offshore platforms and ship structures to cope with harsh environments such as seawater corrosion and wave impact.
