Product Features & Advantages
- Guaranteed Strength: Every coil is tested to ensure tensile strength falls within 400-510 MPa, providing reliable mechanical performance for load-bearing structures.
- Excellent Weldability: Low carbon content (≤0.21%) allows for easy welding without pre-heating or post-weld heat treatment, reducing fabrication costs.
- Superior Formability: SS400 exhibits good ductility and bendability, making it suitable for forming, stamping, and cold bending operations.
- Consistent Quality: Our production is ISO9001:2015 certified, ensuring strict process control from raw material sourcing to final inspection.
- Customizable Dimensions: Thickness, width, and coil weight can be tailored to your specific requirements, minimizing waste and optimizing logistics.
- Global Export Experience: With annual export value exceeding US$50 million, we serve markets across North America, South America, Europe, Asia, Africa, and Oceania, ensuring smooth customs clearance and timely delivery.
- Cost-Effective Solution: Compared to higher-strength grades, SS400 offers a balanced combination of strength and affordability, ideal for general engineering applications.
Ideal Applications
- Structural Steelwork: Beams, columns, channels, and angles for buildings, bridges, and towers.
- Shipbuilding: Hull plates, decks, and bulkheads (non-classified structures).
- General Machinery: Frames, brackets, and support components.
- Automotive Parts: Chassis and underbody parts where moderate strength is required.
- Storage Tanks & Pipes: Low-pressure containers and piping systems.
