The A807/A807M-13 steel grade is a high-strength, low-alloy structural steel that is primarily used in construction and industrial applications. It is known for its excellent mechanical properties and durability.
The chemical composition of the A807/A807M-13 steel grade typically consists of carbon (C), manganese (Mn), phosphorus (P), sulfur (S), silicon (Si), copper (Cu), chromium (Cr), nickel (Ni), and molybdenum (Mo). The exact composition may vary depending on the manufacturer and specific requirements, but the typical ranges are:
– Carbon (C): 0.15-0.25%
– Manganese (Mn): 0.60-1.00%
– Phosphorus (P): 0.035% max
– Sulfur (S): 0.040% max
– Silicon (Si): 0.40% max
– Copper (Cu): 0.20-0.35%
– Chromium (Cr): 0.80-1.10%
– Nickel (Ni): 0.60-0.90%
– Molybdenum (Mo): 0.15-0.25%
These elements contribute to the overall strength and toughness of the steel grade. Carbon provides hardness, while manganese improves the steel’s workability and strength. Phosphorus and sulfur are kept low to ensure good weldability and machinability. Copper enhances corrosion resistance, while chromium, nickel, and molybdenum improve the steel’s overall mechanical properties and resistance to wear and tear.
In terms of mechanical properties, the A807/A807M-13 steel grade has a minimum yield strength of 345 MPa (50 ksi) and a minimum tensile strength of 485 MPa (70 ksi). It also has good elongation, impact resistance, and high strength-to-weight ratio.
These properties make the A807/A807M-13 steel grade suitable for a wide range of applications, including building structures, bridges, machinery, automotive components, and transportation equipment. It is commonly used in the construction of high-rise buildings, bridges, and infrastructure projects where strength and durability are essential.
The A807/A807M-13 steel grade is often used in conjunction with other materials to enhance its properties, such as galvanizing for corrosion resistance or heat treatment for improved hardness and strength.
Overall, the A807/A807M-13 steel grade offers excellent mechanical properties and versatility, making it a popular choice in various industries.
