Product Features & Technical Specifications
- High Toughness: Our SS400 steel plate exhibits excellent impact resistance even at low temperatures, reducing the risk of brittle fracture under heavy loads or dynamic forces. This property is critical for structures in seismic zones or cold climates.
- Pressure Resistance: Designed to withstand high internal and external pressures, the plate maintains structural integrity in applications such as storage tanks, pipelines, and pressure vessels. The guaranteed tensile strength of 400–510 MPa ensures reliable performance under stress.
- Durable & Long-lasting: With balanced chemical composition and controlled rolling processes, the plate offers superior wear and corrosion resistance. Optional surface treatments like hot-dip galvanizing further extend service life in harsh environments.
- Excellent Weldability & Formability: The low carbon equivalent (CEV) allows for easy welding, cutting, bending, and machining without compromising mechanical properties. This reduces fabrication time and costs for contractors.
- Versatile Applications: Ideal for building frames, bridge girders, transmission towers, offshore platforms, heavy machinery, and general structural components. Our plate meets diverse construction standards and can be customized to specific project requirements.

Frequently Asked Questions
Q1: What is the difference between SS400 and ASTM A36 steel plate?
Both are similar low-carbon structural steels. SS400 follows JIS G3101 standard with minimum yield strength of 245 MPa (for thickness ≤16mm) and tensile strength of 400–510 MPa. ASTM A36 has slightly different composition and lower yield point (250 MPa). Our SS400 can often be used as a substitute, but we recommend verifying with specific project codes.

Q2: Can you provide cut-to-size plates for small quantity orders?
Yes. We offer custom cutting and machining services for both large and small quantities. Minimum order quantity may apply, but we accommodate prototype or trial orders.
