What is the S355J2WP steel chemical composition hardness?

At the same time, the company operates a variety of products of related iron and S355J2WP steel chemical composition 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 steel chemical composition 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.

The company has formed a production scale of steel plates, steel pipes, steel profiles, and other products, with a planned layout of science, advanced S355J2WP steel chemical composition technology and equipment, reasonable resource allocation, environmental protection, energy saving and high efficiency. BBN company has become a large-scale iron and steel enterprise integrating steel S355J2WP steel chemical composition production, mineral resource development, steel structure and engineering construction, real estate and modern logistics.

The corten plates S355J2WP steel chemical composition offer high tensile, yield and mechanical strength at the elevated temperature. These plates provide high toughness and harness at the high temperature and cryogenic temperature as well. The application of corrosion Resistant Steel Plates is- these plates are used in the number of industries like landscape building, an automobile company, fertilizers, marine industry. The plate is used in because of its good elasticity, ductility, thermal and electrical conductivity. We follow all the industry-standard both national and international standards.

Oxygen (O) is a harmful element in steel such as S355J2WP steel chemical composition. Although manganese, silicon, iron and aluminum are added to deoxidize the steel at the end of steelmaking, they can not be removed completely. During the solidification of molten steel, the reaction of oxygen and carbon in the solution will produce carbon monoxide, which can cause bubbles. Oxygen mainly exists in the form of FeO, MnO, SiO2, Al2O3 and other inclusions in the steel, which reduces the strength and plasticity of the steel. Especially, it has serious influence on fatigue strength and impact toughness.

S355J2WP steel chemical composition, Q345B steel plate strength has much to do with its thickness. First, the min. yield strength of Q345B steel plate: 345 Mpa for thickness ≤16mm, 335 Mpa for thickness 16-40mm, 325 Mpa for thickness 40-63mm, 315 Mpa for thickness 63-80mm, 305 Mpa for thickness 80-100mm, 285 Mpa for thickness 100-150mm, 275 Mpa for thickness 150-200mm, 265 Mpa for thickness 200-250mm. Second, the tensile strength of Q345B steel plate: 470-630 Mpa for thickness ≤100mm, 450-600 Mpa for thickness 100-250mm.
