SS400 is a type of structural carbon steel known for its straightforward chemical makeup, mainly made up of iron and carbon, along with trace amounts of manganese, phosphorus, and sulfur. It boasts a minimum yield strength of 245 MPa and a tensile strength that falls between 400 and 510 MPa. With its impressive ductility, malleability, and weldability, SS400 is a breeze to work with and shape. It can be processed through hot-rolling or cold-rolling, depending on what’s needed. While it may not be the best choice for high-strength or corrosive settings, it delivers reliable performance for general structural uses, making it a cost-effective option for low to moderate load-bearing tasks.

When it comes to uses and applications, SS400 sheets and plates are a go-to choice in general construction and structural projects, thanks to their low cost and ease of handling. You’ll find them in the making of bridges, buildings, structural beams, industrial platforms, warehouse frameworks, and various machinery parts. SS400 also plays a role in shipbuilding, automotive frames, storage tanks, and railway components. Its good weldability and machinability make it perfect for both welded and bolted structures. Although it’s not ideal for extreme weather or highly corrosive environments, SS400 is still a solid pick for indoor or lightly exposed structures where reliable performance under moderate stress is essential.
