Chemical Composition:
The chemical composition of A1004/A1004M-99(2014) steel grade is determined by the following elements:
– Carbon (C): The carbon content in this steel grade is typically between 0.02% and 0.08%. Carbon is a primary element in steel and its presence affects the hardness, strength, and ductility of the material.
– Manganese (Mn): The manganese content in this steel grade is typically between 0.6% and 1.0%. Manganese helps improve the strength and toughness of the steel.
– Phosphorus (P): The phosphorus content in this steel grade is limited to a maximum of 0.04%. Excessive phosphorus can cause brittleness and reduce the weldability of the steel.
– Sulfur (S): The sulfur content in this steel grade is limited to a maximum of 0.05%. Like phosphorus, excessive sulfur can cause brittleness and reduce the weldability of the steel.
Mechanical Properties:
The mechanical properties of A1004/A1004M-99(2014) steel grade are as follows:
– Tensile Strength: The minimum tensile strength of this steel grade is 440 MPa (64,000 psi). Tensile strength measures the maximum amount of stress a material can withstand before failing under tension.
– Yield Strength: The minimum yield strength of this steel grade is 300 MPa (44,000 psi). Yield strength is the amount of stress that a material can withstand without permanent deformation or failure.
– Elongation: The minimum elongation of this steel grade is 25%. Elongation is the percentage increase in the length of a material before it fractures under tension. It is a measure of the material’s ductility.
– Hardness: The hardness of this steel grade is typically between 85 and 95 HRB (Rockwell B hardness). Hardness is a measure of a material’s resistance to indentation or scratching.
Applications:
A1004/A1004M-99(2014) steel grade is commonly used in the manufacturing of structural components, such as beams, columns, and trusses. It is also used in the construction industry for various applications, including building frames, bridges, and highway signs.
This steel grade is known for its high strength and good weldability, making it suitable for structural applications that require both strength and ease of fabrication.
