JIS G3136 SN400C is a high-quality steel plate, specifically designed for structural applications in the construction industry. It is characterized by a robust chemical composition that ensures exceptional mechanical properties. The chemical composition of SN400C is carefully formulated to provide a balance of strength, ductility, and fatigue resistance.

The primary alloying elements in SN400C include carbon, silicon, manganese, and chromium. These elements contribute to the steel's hardness, tensile strength, and resistance to corrosion. A small addition of titanium further enhances the plate's toughness and weldability.

The mechanical properties of SN400C make it an excellent choice for a wide range of construction applications. It exhibits high yield and tensile strength, ensuring structural integrity under demanding conditions. Its good fatigue resistance makes it suitable for use in反复 loaded components, such as bridges and offshore structures.

One of the key applications of SN400C steel plate is in the manufacturing of pre-stressed concrete products. The high strength and ductility of this steel grade enable the production of long-lasting and reliable concrete beams and columns. Its resistance to corrosion makes it particularly suitable for outdoor applications, such as bridges and viaducts.

In Japan, the use of SN400C steel plate is widespread in the construction industry. One notable example is the Akashi Kaikyo Bridge, which is a suspension bridge connecting two mountainous islands in the Akashi Strait. The bridge's main cables and anchor arms are made from SN400C steel plate, ensuring their longevity and performance under heavy traffic loads.

In conclusion, JIS G3136 SN400C steel plate offers a unique combination of chemical composition and mechanical properties that make it a highly versatile material for construction applications. Its adaptability to various structural forms and its exceptional durability make it a cost-effective choice for projects where structural integrity and longevity are paramount.
