The chemical composition of the fractured fork, analyzed by Optical Emission Spectroscopy (OES), indicated that the forks are made of a common structural steel grade 34Cr4 (W.Nr. 1.7033), see Table 1 .
What type of steel is used for forklift forks?
Forklift tines are usually made from 4340, a very tough steel.
What material are forklift forks made from?
Forklift forks are made from very tough steel, usually 4140 or 4340. These types of steel are used due to their toughness and they maintain a high tensile strength during forging.
Are forklift forks tempered?
The fork are obviously a medium carbon steel and specific temper, so any welding would require a preheat, a high strength filler material followed by a peen job and a post heat.
Can you weld on forklift forks?
Broken forklift fork. Those break at the area of most stress, the bend. You can pre and post heat and weld with 7018 or maybe higher but you will never be able to duplicate the grain structure that was origionally there from forging.
What are forklift forks called?
FORKS. Also known as the tynes, the forks on a forklift are used to make direct contact with a load for transport. They are attached to the forklift carriage and are designed to carry a load from the bottom.
How long are forks on a forklift?
Forklift fork, ITA Class 2, 5720 lbs Capacity per pair at 24″ load center, Measures 48″ length by 4″ width by 1-3/4″ thickness.
Can you drill holes in forklift forks?
Forks should be in good repair, not too worn and never have holes drilled in them for towing.
How do you weld a broken forklift fork?
Welding of Forklift forks
- Preheat to 600*F with a soft flame.
- Postheat to 800-850*F with a soft flame.
- Cool slowly.
- NEVER weld on the face, or under any circumstance the INSIDE RADIUS of the HEEL.
- Normally, never weld within half the diameter of the face. …
- Anything else causes soft spots and weakens the forks from their load rating.
