ASTM A572 grade 50 hot rolled steel coil belongs to high strength low alloy structural steel, produced by hot rolling process. Its chemical composition strictly controls the carbon content (C ≤ 0.23%) and sulfur phosphorus impurities (≤ 0.05%), and achieves a yield strength of ≥ 345MPa through niobium vanadium microalloying, with excellent cold formability.
A572 grade 50 steel plate is widely used in the field of engineering structures, especially suitable for manufacturing load-bearing components such as crane booms and transmission towers. Its welding performance is excellent (carbon equivalent CE ≤ 0.45%), and the low-temperature impact energy at -30 ℃ can still reach over 27J, making it a cost-effective choice for structural steel.
Just like you, 70% customers choose long-term cooperation with BBN steel not only for our good product and service quality, good reputation in the international market, but also for our experienced one-stop raw material supply and further steel processing!
