The materials used in the manufacture of Special Gear are steel materials. Steel; It is an iron and carbon alloy containing a small amount of carbon in its composition, which can be made durable, hard or flexible by quenching. Special Gear can be subjected to high load during operation. In order to increase durability, Special Gear needs heat treatment after manufacturing. The heat treatment is generally applied to steel type materials, thus greatly increasing the strength of the Special Gear. Special Gears cannot be used as they are manufactured, they are subjected to different heat treatment methods according to the working place and material types. The heat treatment ensures the Special Gear surface durability to last for years without breaking or being damaged. The amount of special gear in hardening with the heat treatment method should be selected according to the area of use. Namely; the low amount of hardening causes the Special Gear to be easily crushed and deformed; If it is hardened too much, it causes rapid breakage in the gear. Even if the material of the Special Gear is of high quality and the gear angle is perfect, if it does not have a good heat treatment, rapid wear and cracks and breaks in the gears will occur.
