JIS Hot Rolled SS400 Steel H Beam for Construction
SS400 H-shaped steel (JIS G3101 standard), where "SS" stands for structural steel, "400" stands for a minimum tensile strength of 400 MPa, and "H" stands for an H-shaped cross section optimized for load-bearing structures.
Chemical composition:
Carbon (C): ≤0.22% (balance of strength and weldability).
Manganese (Mn): ≤1.40% (enhanced strength and toughness).
Phosphorus (P) and sulfur (S): ≤0.050% (controlled to minimize brittleness and maximize purity).
Mechanical properties of SS400 structural steel
Tensile strength: 400–510 MPa, meeting structural requirements for heavy-duty applications.
Yield strength:
≥245 MPa (thickness ≤16 mm)
≥235 MPa (16–40 mm)
≥215 MPa (40–100 mm).
Elongation: ≥26%, ensuring ductility under deformation.
Impact toughness: ≥27 J at room temperature, suitable for dynamic or impact loads.
Physical and processing properties of SS400 H-beam
Weldability: Excellent compatibility with arc welding and other common techniques, thanks to moderate carbon content and controlled impurities.
Cold workability: Easy to cut, bend or process without cracking, ideal for on-site fabrication.
Surface treatment: Galvanizing (hot-dip galvanizing) is usually used to enhance corrosion resistance in exposed environments.
Standards and international equivalents for SS400 H-beam for construction
Main standard: JIS G3101 (Japan).
Global equivalent standards:
China: Q235 (GB/T 700).
USA: ASTM A36.
Europe: S235JR (EN 10025).
Construction advantages
Cost-effectiveness: Balances performance and economy with a wide range of standard sizes.
Adaptability: Compatible with bolted or welded connections, simplifying assembly.
Lifespan: Galvanized variants resist rust and reduce maintenance in harsh environments.
