Carbon Steel Bar
Carbon steel bar is produced from carbon steel through hot rolling or cold rolling processes, offering good mechanical properties, strength, and toughness. Depending on carbon content, it can be classified into low-carbon, medium-carbon, and high-carbon steel, each suitable for different applications and processing requirements.
Carbon steel bars are widely used in machinery parts, shafts, gears, bolts, construction components, and engineering machinery, and can be machined, welded, heat-treated, or formed into various shapes.
Key Advantages:
Excellent mechanical properties and strength
Good machinability and weldability
Can achieve different hardness and toughness through heat treatment
Widely applied in machinery, construction, and engineering industries
