Best Services DIN 1.1740/C60U Carbon Structural Steel Round bar
1: C60U steel introduction
C60U steel is a high-quality carbon structural steel, with high strength, hardness and elasticity, but the cold deformation of the plasticity is low, poor cutting, welding and hardenability is also poor, water quenching has a tendency to produce cracks

| Application | C60U steel is widely used in the manufacture of a variety of large forces, working under friction conditions, such as shafts, spring coils, axles, washers, cams and ropes, etc. . In addition, C60U steel is also suitable for high-rise buildings, bridges, tunnels, and other projects that need to withstand a greater pressure because of its high strength and good toughness to withstand greater loads | |
