250A53 steel grade is a high-strength structural steel that is designed to meet the demands of modern engineering and construction. It is commonly used in the construction of heavy-duty structures such as bridges, buildings, and industrial equipment. The steel is known for its excellent mechanical properties and chemical composition, making it a popular choice for applications requiring strength and durability.
Mechanical properties:
– Tensile strength: 530-650 MPa
– Yield strength: 355 MPa
– Elongation: 22%
– Charpy V-notch impact strength: 27J at -20°C
Chemical composition (typical):
– Carbon (C): 0.20%
– Manganese (Mn): 1.70%
– Silicon (Si): 0.50%
– Phosphorus (P): 0.035%
– Sulfur (S): 0.035%
– Chromium (Cr): 0.30%
– Molybdenum (Mo): 0.25%
– Nickel (Ni): 0.30%
These properties make 250A53 steel grade an ideal choice for applications requiring high strength, good weldability, and resistance to corrosion. Additionally, it can be easily fabricated and welded, making it suitable for a wide range of construction projects.
