Fasteners are devices that are employed in connecting an array of metal components in the system. Hot forged fasteners are precisely shaped at high temperatures using compressive forces. These fasteners are made with alloys of carbon and iron, which are alloyed at extreme temperatures between 950 to 1250 degrees C. These high strength, hardened components possess a finer uniform grain structure having higher tensile and fatigue strength over other steel grades. Steel at forging temperatures becomes highly malleable and ductile, allowing the fasteners to be designed in different sizes and specifications.
Difference Between Hot Forged Bolts Vs Cold Forged Fasteners
| Feature | Hot Forged Bolts | Cold Forged Fasteners |
|---|---|---|
| Temperature | High (above recrystallization) | Room temperature |
| Strength | Tough and ductile | Strong and hard |
| Surface Finish | Rougher, may need machining | Smooth and precise |
| Size/Complexity | Large, complex shapes | Small, simple shapes |
| Cost | Higher for small production | Economical for mass production |
| Applications | Heavy-duty and extreme conditions | High-volume small parts |
Eye bolts are fasteners that act as a connection point for anchoring, rigging, hoisting different modules in stress-induced environments. In such systems, corrosion is at the highest degree leading to degradation of the bolts. The best way to mitigate this problem is the hot dip galvanizing process. In this process, the eye bolts are surfaced cleaned, and dipped in hot baths containing zinc. Zinc in these baths will coat itself on the metal surface and protect it from corrosion. The barrier of zinc provides cathodic protection to the steel. This means that the zinc grade will corrode instead of the steel when they come in contact with corrosive media. The sacrificial zinc grade is an excellent defense mechanism against corrosion and improves the durability and longevity of the steel grade.
