As a benchmark in medium-carbon high-strength carbon carbon structural steel, the 50#/C50E/1050 Carbon Steel Coil adheres to international standards including GB/T 699-1988, EN 10132-4, and ASTM A29. With a precisely controlled carbon content of 0.47%-0.55%, it delivers outstanding mechanical properties: tensile strength ≥630MPa, yield strength ≥375MPa, and elongation of 12%-20%. After quenching and tempering treatment, it achieves a hardness of HRC52-54, enhancing surface wear resistance by over 30%, making it ideal for manufacturing high-load gears, automotive crankshafts, hydraulic piston rods, and precision molds.
