2. Construction industry: It is used for making structural components, such as beams, columns, and fasteners.
3. Machinery and equipment: C15 is suitable for producing machine parts, gears, shafts, and bolts.
4. Oil and gas industry: Due to its good strength and machinability, C15 steel is used for manufacturing valves, fittings, and other components in the oil and gas sector.
5. General engineering: C15 is a versatile steel grade that can be used in various general engineering applications, including tool making and fabrication.

Mechanical Properties:
The mechanical properties of C15 steel grade depend on factors such as heat treatment and processing conditions. However, typical values are as follows:
– Tensile strength: 460-580 MPa
– Yield strength: 290-390 MPa
– Elongation: 18-22%
– Hardness: 150-180 HB

Chemical Composition:
The chemical composition of C15 steel grade is as follows:
– Carbon (C): 0.12-0.18%
– Silicon (Si): 0.15-0.35%
– Manganese (Mn): 0.30-0.60%
– Phosphorus (P): 0.035% max
– Sulfur (S): 0.035% max

It is important to note that these values are approximate and may vary depending on the specific standards and manufacturing processes used. Therefore, it is always recommended to refer to the relevant specifications and standards for accurate information on the mechanical properties and chemical composition of C15 steel grade.
