C16 steel grade is a low carbon steel used in various engineering applications due to its excellent mechanical properties and chemical composition.

Mechanical Properties:
– Tensile Strength: The tensile strength of C16 steel grade is typically between 430-580 MPa, which makes it suitable for structural applications that require high strength and durability.
– Yield Strength: The yield strength of C16 steel grade is around 275-355 MPa, indicating its ability to withstand significant loads without permanent deformation.
– Elongation: C16 steel grade has a minimum elongation of 20%, which means it can stretch without breaking, allowing for better formability and flexibility in different manufacturing processes.
– Hardness: The hardness of C16 steel grade is usually in the range of 140-190 HB, providing good resistance against wear and abrasion.

Chemical Composition:
– Carbon (C): C16 steel grade contains a low carbon content of 0.13-0.18%. This low carbon content contributes to its excellent weldability and formability.
– Manganese (Mn): The manganese content of C16 steel grade ranges from 0.60-0.90%. Manganese enhances the strength and hardenability of the steel, improving its mechanical properties.
– Phosphorus (P): C16 steel grade has a maximum phosphorus content of 0.050%, ensuring good weldability and preventing the formation of brittleness in the steel.
– Sulfur (S): The sulfur content in C16 steel grade is limited to a maximum of 0.050%, which helps in improving machinability and reducing the occurrence of cracks during hot working processes.
– Silicon (Si): C16 steel grade contains a small amount of silicon (0.10-0.35%). Silicon improves the strength and hardness of the steel and promotes better resistance to corrosion and oxidation.

Overall, C16 steel grade with its specific mechanical properties and chemical composition is an essential component in the construction of numerous engineering marvels, such as bridges, buildings, and machinery, where high strength, durability, and formability are required.
