A514 grade B is a specific grade of high-strength, quenched and tempered alloy steel plate that belongs to the ASTM A514/A514M specification. This specification sets the requirements for the chemical composition and mechanical properties of A514 grade B steel.
A514 grade B steel plate offers exceptional strength and toughness properties, making it suitable for applications where high structural strength is required. It has a minimum yield strength of 100 ksi (690 MPa) and a minimum tensile strength of 110-130 ksi (760-895 MPa). The steel is alloyed with elements such as carbon, manganese, phosphorus, sulfur, silicon, nickel, chromium, molybdenum, boron, vanadium, titanium, and copper to achieve its desired mechanical properties.
The quenching and tempering process provides A514 grade B steel with enhanced hardness, improved weldability, and resistance to wear and impact. As a result, it is commonly used in construction machinery, mining equipment, crane booms, truck frames, and other heavy-duty applications.
In summary, A514 grade B steel sheet is a high-strength, quenched and tempered alloy steel plate that offers superior strength and toughness properties. It is ideal for applications requiring high structural strength and can withstand demanding conditions in various industries.
