S355J2G3 is a non-alloy, structural-grade steel widely used in various industrial sectors. It is a low-carbon and high-tensile strength steel available in different forms, such as plates, coils, and sheets. This blog post will provide a complete guide to the S355J2G3 plates and their applications.
What Are S355J2G3 Plates?
S355J2G3 plates are a type of non-alloy steel plates that are used in various industrial applications. These plates are made of low-carbon steel and have high tensile strength. They are available in different forms, such as hot-rolled, cold-rolled, and normalized. S355J2G3 plates are used to construct bridges, buildings, and other structures that require high strength and durability.
Chemical Composition Of S355J2G3 Plates
S355J2G3 plates are composed of different elements such as carbon, manganese, silicon, and phosphorus. The chemical composition of S355J2G3 plates is ideal for applications where high strength and durability are required. The carbon content of S355J2G3 plates is less than 0.22%, which means they are low-carbon steel. The manganese content is around 1.6%, which provides strength and toughness to the material.
Applications Of S355J2G3 Plates
S355J2G3 plates are used in various industrial applications such as construction, shipbuilding, and offshore structures. These plates are also used to manufacture heavy machinery, mining equipment, and cranes. S355J2G3 plates are also used to produce wind turbines, oil rigs, and pipelines. The high strength and durability of S355J2G3 plates make them suitable for harsh environments.
Welding Of S355J2G3 Plates
S355J2G3 plates are easily weldable and welded using various welding techniques such as SMAW, FCAW, GTAW, and GMAW. The welding of S355J2G3 plates requires preheating and post-weld heat treatment to avoid cracking and brittleness. The low carbon content of S355J2G3 plates makes them easier to weld than high-carbon steel.
Plate Sizes And Dimensions
S355J2G3 plates are available in different sizes and dimensions. The thickness of S355J2G3 plates ranges from 6mm to 200mm. The width and length of these plates vary according to the customers’ requirements. These plates are available in different grades, such as S355J2G3+N, S355J2+N, and S355J2G3C.
Conclusion
In conclusion, S355J2G3 plates are a type of non-alloy steel plates that are widely used in various industrial applications. They have high tensile strength and provide durability and strength to the structures where they are used. The low carbon content of S355J2G3 plates makes them easily weldable and available in different sizes and dimensions. They are popular in construction, shipbuilding, offshore structures, manufacturing, and other industries.
