ASTM A572-50 steel is high-strength, low-alloy structural steel. It is commonly used in construction due to its high strength-to-weight ratio. It is also used to build heavy machinery and construction equipment for this same reason.This steel has many applications including bridges, buildings, freight cars, and more. Its high strength-to-weight ratio means less steel can be used to hold the same amount of weight, meaning it is high value.A572-50 steel is less formable than other grades of A572, but for the most part it has good formability, weldability, and machinability. It has excellent ductility due to its chemical composition, and is very resistant to corrosion.

Scope of
Application
For there is no shape control in the final cooling process, dimension accuracy of hot rolled steel plate is not as good as cold rolled steel. So it is mostly used in applications with lower dimension requirement. Many Steel Products are included in Railway tracks, bridge steel and construction steel.
