Sri Sakthi Steels

C45 carbon steel plates are used for a wide range of applications that require high strength, hardness, and wear resistance, such as manufacturing machinery components, automotive parts, and industrial tools. Common uses include making gears, shafts, axles, bolts, and dies. Its properties can be adjusted through heat treatment processes like quenching and tempering.  Mechanical and automotive industries

Gears, shafts, and axles: C45 steel is ideal for these components due to its strength and ability to withstand wear. 

Bolts and studs: The material's durability makes it suitable for fasteners like bolts, studs, and spindles. 

Machinery parts: It is used in various parts for machinery and equipment in both the mechanical and automotive sectors. 

Tool and die making

Cutting tools: C45 plates are used for making tools like chisels, milling cutters, and drill bits because of their hardness and wear resistance. 

Moulds and dies: The steel's ability to withstand repetitive stress and high wear makes it suitable for manufacturing moulds and die sets. 

Other applications

Shaping machinery: It can be used in components for shaping machinery due to its rigidity and ability to withstand difficult working conditions.
