The chemical composition of A673/A673M-17 steel grade may vary depending on the manufacturer and specific grade within this standard. However, the general chemical composition requirements for this steel grade are as follows:
– Carbon (C): The maximum carbon content is specified to be 0.15%.
– Manganese (Mn): The maximum manganese content is specified to be 2.00%.
– Phosphorus (P): The maximum phosphorus content is specified to be 0.030%.
– Sulfur (S): The maximum sulfur content is specified to be 0.040%.
– Silicon (Si): The maximum silicon content is specified to be 0.30%.
These chemical composition requirements ensure that the steel grade meets the necessary strength and ductility properties for its intended applications.
The mechanical properties of A673/A673M-17 steel grade are specified in the standard. The key mechanical properties that are typically provided include:
– Tensile Strength: The minimum tensile strength is specified. It represents the maximum stress that the steel can withstand before breaking.
– Yield Strength: The minimum yield strength is specified. It represents the stress required to permanently deform the steel.
– Elongation: The minimum elongation is specified. It represents the ability of the steel to deform before fracture.
– Reduction in Area: The minimum reduction in area is specified. It represents the amount of localized deformation that occurs in the steel during testing.
The specific values for these mechanical properties will depend on the grade of A673/A673M-17 steel and are provided by the manufacturer or in the standard itself.
The standard number for A673/A673M-17 steel grade is ASTM A673/A673M-17. This standard is issued by the American Society for Testing and Materials (ASTM) and provides the specifications for normalized high-strength low-alloy structural steel plates.
