EN 41B (Nitriding steel)

EN41 is a chromium aluminium molybdenum steel specification usually supplied in the hardened and tempered ‘R’ or ‘S’ condition. It offers high wear resistant properties together with toughness and ductility. It is defined by its suitability for nitriding from which EN41 can give a hard ware resistant case up to 68HRc, better than achievable with the similar nitriding grade EN40B.

Applications for EN 41 steel

EN41 is suited for applications that required excellent resistance to wear and abrasion. Typical applications include connecting rods, small extruders, valve stems, dies. It is widely used in the automotive, textile and general engineering industries

Suitable for applications requiring a resistance to wear, it is also suitable for other applications such as

  • Brick press plates
  • Clutch plates
  • Gudgeon
  • Track
  • Shackle pins
    • Grade C Si Cr Mo Al Mn Ni P S
