What is the mechanical properties of S355J2WP seaport buildings used steel?

At the same time, the company operates a variety of products of related iron and S355J2WP seaport buildings used steel steel enterprises. Annual sales of steel 3.6 million tons, standing stock of 400000 tons, has developed more than 10000 users. The company has a first-class marketing service system, strong storage and transportation capacity and supporting supply, cutting distribution capacity, and gradually build it into an important marketing channel. The company has obtained S355J2WP seaport buildings used steel ISO9001:2000 quality system certification, A-level credit unit of the people's Bank of China, and is an excellent supplier of many large state-owned enterprises.

Weathering steel S355J2WP seaport buildings used steel generally adopts the process route of refined material entering the furnace-smelting (converter, electric furnace-microalloying treatment-argon blowing-LF refining-low superheat continuous casting (feeding rare earth wire)-controlled rolling and controlled cooling. During smelting, the scrap steel is added to the furnace along with the charge and smelted according to the conventional process.

Steel can be divided into ordinary steel and special steel, which is an important symbol of a country's steel production level. The special steel includes spring steel, round steel, die steel, heat-resistant steel, wear-resistant steel, bearing steel and so on. Compared with ordinary steel, the S355J2WP seaport buildings used steel special steel has better physical properties, higher strength, stronger compressive strength and better accuracy. At the same time, the special steel has better chemical properties, such as high temperature resistance, low temperature resistance and corrosion resistance.

S355J2WP seaport buildings used steel, Q345C steel plate is a kind of weldable low carbon engineering structure material, which is generally produced by continuous rolling mill. The carbon content of Q345C steel plate is less than 0.25%. The yield strength σ0.2 of Q345C steel plate is 300- 800MPa and the yield ratio is 0.65- 0.95. Q345C steel plate has excellent low temperature toughness. That is mainly owe to the solid solution of alloy elements (Mn, Si, Al, Cr, etc.), grain refinement (Nb, V, Ti, etc.), precipitation hardening (Nb, V, Ti, etc.), phase transformation strengthening (Mn, Si, Mo, etc.), and controlled rolling and controlled cooling, etc. new technologies.

EN 10025-2 steel includes S235 steel (S235JR, S235J0, S235J2), S275 steel (S275JR, S275J0, S275J2), S355 steel (S355JR, S355J0, S355J2, S355K2), S450 steel (S450J0). According to EN 10025-2, the thickness of S450J0 plate is within 3-150mm. The S355J2WP seaport buildings used steel, S235 steel, S275 steel and S355 steel plate thickness is ≤250mm. However, the S235J2, S275J2, S355J2 and S355K2 plates limitation is ≤400mm.
