High quality Carbon Steel H Beam SS400
SS400 structural steel has excellent mechanical properties, including high strength, good toughness and easy fabrication, and is commonly used in construction, infrastructure and industrial applications.
H-beam, also known as wide flange beam, is a structural steel member with an "H" shaped cross-section. The design consists of:
Flange: A horizontal member that provides resistance to bending.
Web: A vertical member that connects the flanges and resists shear forces.
SS400 H-beams are manufactured through hot rolling or welding processes to ensure uniformity and strength.
The chemical composition of SS400 carbon steel typically includes the following elements:
Carbon (C): ≤ 0.25%
Silicon (Si): ≤ 0.60%
Manganese (Mn): ≤ 1.60%
Phosphorus (P): ≤ 0.050%
Sulphur (S): ≤ 0.050%
This composition ensures that SS400 mild steel beam has a balanced combination of strength and ductility for structural applications.
SS400 carbon steel h beam has the following key mechanical properties
Tensile strength: 400–510 MPa
Yield strength: ≥ 245 MPa
Elongation: ≥ 21% (thickness ≤ 16 mm)
Hardness: Typically around 120 HB (Brinell hardness)
These properties make SS400 mild steel h beam versatile, able to carry large loads while maintaining structural integrity.
Advantages of SS400 H beams
High strength-to-weight ratio: Provides excellent load-bearing capacity without excessive weight.
Easy to manufacture: can be cut, welded, drilled and formed using standard tools.
Durability: resists deformation and wear under normal operating conditions.
