SS400 Structural Steel Overview

SS400 is a Japanese JIS G3101 standard structural steel grade. It is widely used for its good mechanical properties and excellent weldability. SS400 is considered a mild steel suitable for general structural applications.

The chemical composition of SS400 includes carbon (≤0.17%), manganese, silicon, and small amounts of phosphorus and sulfur. Its low carbon content ensures good forming capacity and ease of fabrication. The mechanical strength is moderate but reliable for everyday applications.

SS400 is typically supplied in hot-rolled condition, providing uniform thickness, smooth surfaces, and consistent mechanical behavior. It can be welded using common welding methods and can be processed by cutting, bending, and machining.

Applications include steel plates, beams, channels, angle bars, steel pipes, construction frames, bridge components, and machinery parts. SS400 is commonly used in Asia-Pacific markets for general engineering solutions.
