Understanding the Composition and Properties of CK25 Steel Grade

CK25 is a carbon steel grade with a nominal carbon content of 0.22%. It is a low carbon steel that is used primarily for applications requiring moderate strength and good machining properties. The chemical composition of CK25 steel includes the following elements:

– Carbon (C): 0.22%
– Silicon (Si): 0.15-0.35%
– Manganese (Mn): 0.30-0.60%
– Phosphorus (P): 0.035% maximum
– Sulfur (S): 0.035% maximum

The composition of CK25 steel provides it with certain mechanical properties. These properties determine its suitability for specific applications. The mechanical properties of CK25 steel grade include the following:

– Tensile Strength: The tensile strength of CK25 steel is typically around 500-700 MPa. This indicates its ability to resist pulling forces without deforming or breaking.
– Yield Strength: The yield strength of CK25 steel is typically around 270 MPa. It is the stress at which the material begins to deform permanently.
– Elongation: The elongation of CK25 steel is typically around 18-25%. It is the percentage increase in length of the material when subjected to tensile stress.
– Hardness: The hardness of CK25 steel is typically in the range of 130-170 HV. It measures the material’s resistance to indentation or scratching.

In addition to these mechanical properties, CK25 steel also exhibits good machinability. It can be easily shaped, drilled, and turned on machine tools, making it suitable for various industrial applications.

Overall, CK25 steel is a low carbon steel with moderate strength and good machining properties. Its composition and mechanical properties make it suitable for applications where strength and machinability are important factors.
