Q235C is a common carbon structural steel widely used in China. Its chemical composition includes carbon, manganese, silicon, sulfur, and phosphorus, with a carbon content of approximately 0.14% to 0.22%. The "Q" in Q235C stands for "yield strength," "235" indicates its yield strength of 235 MPa, and "C" represents its quality grade. This steel offers good plasticity and toughness, making it suitable for manufacturing various mechanical parts and engineering structures. Due to its excellent processing performance and low cost, Q235C is highly popular in industrial production.
