The A657/A657M-13 steel grade is a low carbon, high strength, and low alloy steel with improved formability. Its chemical composition consists of carbon, manganese, phosphorus, sulfur, silicon, nickel, chromium, molybdenum, and copper.
The mechanical properties of A657/A657M-13 steel grade include a minimum tensile strength of 480 MPa, a minimum yield strength of 345 MPa, and a minimum elongation of 20%. It also has good weldability and toughness.
This steel grade is commonly used in structural applications such as buildings, bridges, and transmission towers, where high strength and formability are required. It is also used in automotive components, shipbuilding, and manufacturing machinery.
The A657/A657M-13 steel grade is defined by the ASTM A657/A657M-13 standard, which specifies the requirements for carbon and high-strength low-alloy structural steel shapes, plates, and bars for welded, riveted, or bolted construction.
In conclusion, the A657/A657M-13 steel grade is a versatile and high-performance material that offers excellent strength, formability, and weldability. It finds wide applications in various industries, where its properties and performance make it a preferred choice.
