A711/A711M-17 Steel Grade is a specification set by the American Society for Testing and Materials (ASTM) for low carbon and high-strength steel plates. This specification is widely used in the construction industry for structural applications.
The chemical composition of A711/A711M-17 Steel Grade is as follows:
– Carbon (C): The maximum carbon content is 0.22%.
– Manganese (Mn): The maximum manganese content is 1.25%.
– Phosphorus (P): The maximum phosphorus content is 0.025%.
– Sulfur (S): The maximum sulfur content is 0.030%.
– Silicon (Si): The maximum silicon content is 0.15%.
– Copper (Cu): The maximum copper content is 0.35%.
– Nickel (Ni): The maximum nickel content is 0.25%.
These chemical composition requirements ensure that the steel has good weldability, formability, and toughness.
The mechanical properties of A711/A711M-17 Steel Grade include:
– Tensile Strength: The minimum tensile strength is 65,000 psi (448 MPa).
– Yield Strength: The minimum yield strength is 50,000 psi (345 MPa).
– Elongation: The minimum elongation is 20% in 8 inches and 23% in 2 inches.
These mechanical properties indicate the steel’s ability to withstand external forces and deformations without breaking.
The A711/A711M-17 Steel Grade standard number is assigned by ASTM to identify this specific steel grade.
Understanding the chemical composition and mechanical properties of A711/A711M-17 Steel Grade is important for selecting the appropriate steel material for a specific application. It ensures that the steel meets the required strength and durability requirements.
