Forged One Piece Rollers

Rock Solid Performance

  • Retains grain integrity resulting in maximum grain strength
  • Reduces and refines the coarse cast grain structure. Forging does NOT change the volume or density of the steel
  • Uniform grain size and directional flow maximize strength

Metallurgical Expertise Makes All the Difference

Illustration | Step Forging Hammer

Steel is Forged Between 1150°C and 850°C (2102°F to 1562°F). This develops a fine grain structure. Forging reduces and refines the coarse cast grain structure. Forging does NOT change the volume or density of the steel. Cutting off the grain in a single diameter forging severely weakens the part. Step forgings retain their grain integrity resulting in maximum grain strength. Directional grain strength is preserved by “bending” the grain flow around the corners of the steps.

Benefits

  • Structural Strength
    Casting defects are “healed” by hammering the hot steel. The hammering eliminates the voids and defects inherent in casting.
  • Directional Strength
    Uniform grain size and directional flow maximize strength.
  • Impact Strength
    Proper orientation of grain flow combined with a more predictable and precise heat treatment produces impact resistance and cold weather toughness.
