In hot forging, where the workpiece, or in this case, the fastener, is heated to a temperature that is roughly 75% of its melting temperature, the metal is shaped with the use of heat. The makers of hot forged fasteners in India utilise one or more external processes to form the fastener into the appropriate shape. Any hot forged fasteners producer in India will typically use external procedures like pressing, upsetting, and hammering on the workpiece or the fastener.

Cold forging employs ambient temperature as opposed to hot forging, which heats the material to around 75% of its melting point. Therefore, the temperature at which the fastener is forged is the primary distinction between hot-forged and cold-forged fasteners. Hot forged fasteners are produced using a method that prevents strain hardening at high temperatures, unlike the production process used for cold forged fasteners, which uses strain hardening to boost strength.

So employing these hot forged rivets has a number of advantages. For instance, using a hot forging method will result in a material with low hardness and great ductility, as well as the best yield strength attributes. The metal's cast, coarse grain structure will disintegrate during the hot forging process. And finer grains will take the place of the coarse grains. Once the ingot's size has been reduced, this is feasible. After hot forging, makers of hot forged bolts typically give the fasteners further heat treatment.

What is hot forging ?

It is a method for transforming the hot metal state into a predetermined shape. Before being incorporated into another metal piece, a metal is quickly heated to the proper temperature using electric current. When the material is too wide or not flexible enough, bolts are heated generated.
