SS400 sheets and plates are carbon steel materials primarily composed of iron with small amounts of carbon, manganese, phosphorus, sulfur, and silicon. Known for their excellent weldability and formability, they exhibit a minimum tensile strength of around 400–510 MPa and a yield strength of approximately 245 MPa. The material also provides good ductility, impact resistance, and toughness under various conditions. These mechanical properties make SS400 ideal for applications requiring dependable structural integrity and ease of fabrication in demanding environments.
