CK45 Steel Supplier in India | High-Quality Medium Carbon Engineering Steel

CK45 steel is a popular medium carbon steel widely used in general engineering applications. It is known for its excellent balance of strength, toughness, and machinability, making it a versatile and economical choice. This grade can be hardened and tempered to achieve a good range of mechanical properties, making it suitable for a wide variety of components that require moderate strength and wear resistance. At Jupiter Steels, based in Delhi, we are a trusted stockist and supplier of CK45 steel, providing certified material to customers throughout India, including key industrial regions like Manesar, Haryana, and beyond.


The reliable performance of CK45 steel is a direct result of its carefully controlled chemical composition. The key alloying elements and their typical weight percentages are:

  • Carbon (C): 0.42 – 0.50%
  • Manganese (Mn): 0.50 – 0.80%
  • Silicon (Si): Max 0.40%
  • Sulfur (S): Max 0.05%
  • Phosphorus (P): Max 0.05%

  • Medium Carbon (C): The carbon content is the defining feature of CK45 steel. It provides the necessary strength and hardness, allowing the steel to be heat-treated to achieve its required mechanical properties.
  • Manganese (Mn): Manganese improves the steel’s hardenability and tensile strength.

In its normalized condition, CK45 steel typically has a hardness in the range of 190-210 HB. It can be heat-treated to achieve a higher hardness, depending on the specific application.

  • Good Tensile Strength: It provides sufficient strength for a wide range of engineering applications.
  • Good Machinability: Due to its composition, it can be easily machined into complex shapes.
  • Good Weldability: CK45 steel can be readily welded, though pre-heating may be required for thicker sections.
  • Versatility: It is a general-purpose grade suitable for a variety of uses.

CK45 steel is a versatile grade used for a wide range of engineering components. Key applications include:

  • Shafts and Axles
  • Pins and Studs
  • Gears and Bolts
  • Connecting Rods
  • General structural parts in machinery and automotive industries.
