S45CB high quality carbon steel rod

S45CB high quality carbon steel wire rod is a kind of medium carbon high quality steel material, with high strength and relatively poor hardenability, so it is generally used in normalizing state. When the mechanical properties are required to be high, the tempering treatment can be used to improve its comprehensive performance.

S45CB high quality wire rod has the following physical and mechanical properties:

Density: about 7.85g/cm³

Elastic modulus: high, the specific value may vary due to different production conditions and heat treatment methods

Tensile strength: usually not less than 600MPa

Yield strength: usually not less than 355MPa

Elongation: generally not less than 16%

Section shrinkage: usually not less than 40%

Hardness: Without heat treatment, the hardness is generally not more than 229HB; After annealing, the hardness is further reduced to no more than 197HB. After quenching and tempering treatment, the hardness can be significantly increased to meet the needs of specific applications.

Notes for S45CB high quality carbon steel rod:

1, when using S45CB high-quality wire rod, it is necessary to choose the appropriate heat treatment and processing method according to the application scenario.

2. Due to its poor hardenability, it is easy to deform and crack during quenching, so it is necessary to strictly control the quenching temperature and cooling speed.

3, in the cutting process, to choose the right tool and cutting parameters, so as to improve processing efficiency and product quality.

S45CB high quality wire rod is a kind of steel product with high strength, good mechanical properties and wear resistance, which is widely used in many fields such as machinery manufacturing and automobile manufacturing. When in use, attention should be paid to selecting the appropriate heat treatment and processing method to ensure that its performance is fully utilized.
