About EN31 Steel

EN31 Steel is a high carbon alloy steel which is used for a broad range of applications where surface hardness and excellent wear properties are required. It is widely used in bearings, precision engineering components, and other applications. This steel grade can be used for heat treatment to enhance its mechanical properties. It is suitable for industrial applications where heavy loads and constant use are necessary.

Types of EN31 Steel

As EN31 Steel Suppliers in Pune, we provided different types of steel bar according EN31 according to resistance which are given below.

  • EN31 Round Bar - These are round bars that are cylindrical in shape and are commonly used for shafts, rollers, bearings, and precision parts. They have very good heat treatable hardness and wear resistance.
  • EN31 Flat Bar - EN31 flat bars are widely employed in tool manufacturing, tool steel dies and machine components that demand a high level of strength and dimensional stability. They can be easily machined prior to hardening.
  • EN31 Bright Bar - Manufactured with a smooth surface finish and close dimensional tolerances, bright bars are ideal for precision engineering applications. They are more machinable and look better.
  • EN31 Black Bar - Black bars are left with the original hot rolled finish and are typically applied when surface finish is not as important. They can be used for heavy engineering and forging.
  • EN31 Forged Bar – Fought bars are produced to improve mechanical properties and grain structure, used in high-strain industrial parts. They have a stronger toughness and durability.
  • EN31 Annealed Steel - Annealed EN31 is less hard than EN31 and is easier to machine and manufacture prior to final heat treatment. It is generally used in complicated machining process.
