1 The following elements may be present to the limits stated: copper 0.25%,nickel 0.25%.
2 Limlts specified are for soluble or total aluminium.
3 Applies to niobium,vanadium and titanium only.However,vanadium greater than 0.10% is not permitted.● Carbon (C), which contributes to the steel's strength and hardness.
● Silicon (Si), that improves the steel's strength and resistance to atmospheric corrosion.
● Manganese (Mn), which enhances the steel's strength, toughness, and hardenability.
● Phosphorus (P), a trace element that can affect the steel's ductility and toughness if present in higher amounts.
● Sulfur (S), another trace element that can negatively impact weldability if present in excess.
● Chromium (Cr), which can improve the steel's corrosion resistance.
● Molybdenum (Mo), an alloying element that enhances the steel's strength at high temperatures and its resistance to creep.
● Aluminum (Al), used to improve the steel's resistance to scaling at high temperatures.
● Titanium (Ti), used to control the grain size and improve the steel's strength.
● Micro-alloying elements, which can include elements like niobium or vanadium that further refine the steel's properties.CLICK HERE➡What Is AS1163 STANDARD

t nominal thickness● Yield Strength: The minimum yield strength for AS1163 C350L0 is 350 MPa, which is indicated by the "350" in its grade name . This measure of strength is crucial as it indicates the point at which the steel begins to deform plastically under load.
● Tensile Strength: The tensile strength, or ultimate tensile strength, for AS1163 C350L0 is 430 MPa, indicating the maximum stress the material can withstand before breaking .
● Elongation (A): The elongation percentage, which measures the percentage of deformation before fracture . This indicates the material's ductility and ability to absorb energy before failure.Applications
● Structural Engineering: They are used for constructing columns, beams, and support structures in buildings and bridges, offering superior load-bearing capabilities.
● Piping Systems: Ideal for industrial and infrastructure projects due to their hollow cylindrical shape, used for transporting fluids and gases.
● Infrastructure Development: Employed in bridge construction and retaining walls, providing strength and resistance to environmental factors.
● Architectural Applications: Incorporated into façade systems and canopies for structural support and aesthetic appeal.
● Industrial and Manufacturing: Used in machinery frames and material handling systems for their robustness and adaptability.
