Mills & Kilns > Fored Steel Fabricated Girth Gears

FORGED STEEL

Use forged steel fabricated girth gears to overcome your cast steel cracking problems. Forged steel gives the highest crack and impact resistance.

HOFALLOY FORGED MATERIAL

Hofalloy 1 Forged Gear Rim Material conforms to:

  1. AGMA 2001 Grade 2 specification.
  2. Hardness 330 – 360 BHN.
  3. 3:1 Forging Reduction.
  4. Induction Hardenable.
  5. Site weld repairable in the event of a catastrophic mishap.

STOCKED INSURANCE SPARE MATERIAL

Use one plate to suit a variety of gears On Site:

  1. FORGED HOFALLOY plate can be used as an insurance spare to cover many different girth gears.
  2. Reduces manufacturing lead time.
  3. Lowers insurance premiums.
