SM540 Hot Rolled Steel C Channel

SM540 c channel steel is a high strength structural steel commonly used in building and engineering applications. It belongs to the Japanese Industrial Standard (JIS) series and is particularly suitable for applications where durability, load bearing capacity and resistance to deformation are important.

Chemical Composition

The chemical composition of SM540 channel bars typically includes:
Carbon (C): ≤0.20%
Silicon (Si): ≤0.60%
Manganese (Mn): 0.60%–1.60%
Phosphorus (P): ≤0.030%
Sulfur (S): ≤0.030%
These limits ensure that the steel maintains its high strength while providing good formability and weldability.

Mechanical properties

Yield strength (ReH): ≥540 MPa
Tensile strength (Rm): 600–760 MPa
Elongation (A): ≥16%
Impact toughness: Excellent, especially at low temperatures, depending on specific application requirements.

SM540 channel steel beam is significantly stronger than S235JR c section steel, S275JR structural channel or SM400 c channel steel grades, making it ideal for demanding applications.

Dimensions and shapes

SM540 channel steel beams are available in various sizes: 50x37x4.5 mm; 63x40x4.8 mm; 80x48x5.0 mm; 100x63x6.0 mm, etc. GNEE can provide larger sizes on request.

Advantages: SM540 channel steel has an extremely high strength-to-weight ratio and excellent toughness even at low temperatures. At the same time, SM540 structural channel steel also has good machinability and weldability, suitable for applications where maximum strength and durability are required.
