1045/C45 Steel
1045/C45 steel is defined as medium carbon steel which has 0.4%-0.5% Carbon.It offers good weldability, good machinability, high strength and impact properties,but low in hardenability because of lack of suitable alloying elements.
1045 Round bar is used in a variety of industry sectors for applications requiring more strength than low carbon mild steels. Some typical applications for 1045 round bar are axles, bolts, connecting rods, studs, rams, pins, rolls, spindles, ratchets, crankshafts, torsion bars, sockets, worms, light gears, guide rods etc.
Advantages of carbon steel
- Cost-effective: Carbon steel is relatively inexpensive to produce, requiring only small amounts of alloying elements to achieve the desired mechanical properties.
- High strength: Carbon steel has higher strength than ordinary steel and maintains good mechanical properties even at high temperatures. This makes it the preferred material in many important application areas, such as construction, shipbuilding, automotive, etc.
- Easy to manufacture: Carbon steel is a very easy material to machine and manufacture, and can be cut, drilled, punched, etc. through a variety of machining methods, greatly facilitating the production process.
- Good ductility: Carbon steel has good ductility and can be processed by forging, extrusion, stretching, etc. according to their needs to achieve different shapes of finished products.
In conclusion, carbon steel is a cost-effective, high-strength, easy-to-manufacture material with good ductility that is widely used in various fields.
