Forged steel is an alloy of carbon and iron that is compressed under extreme pressure to make a very hard and strong substance. It has been used for thousands of years to create all types of materials. Modern forged steel bars are conducted using specialized machines or hydraulic hammers. There are many things to take into consideration when understanding the benefits of forged steel. In order to make forged steel, the metal can either be kept at room temperature or heated to high temperatures. While the heat treatment higher the temperature, the easier it is for the metal to take shape and less likely to crack.

Hope this helped in getting a brief understanding of the forged steel.

I can not agree. Steel has a grainy structure (crystals), when the hammer strikes the steel structure, it changes the shape of these grains, they become elongated and flatter. After casting, the steel has defects in the form of uneven grain structure as well as empties in the metal body (all this reduces its strength).

When forging a metal, the grain structure is leveled and becomes the same elongated and flattened and the voids inside the steel are eliminated. The elongated grain perceives bending and torsional loads better, and the multidirectional arrangement of the grain in the metal body also increases its tensile strength, compression and shear. The main increase in strength is achieved by eliminating defects in metal and leveling its structure. If you subject the forged steel to annealing, its strength will decrease as the grains become back to a more striking shape.

Of course, steel becomes stronger, but the increase in strength is not particularly high compared with temperature treatment.

As a rule, for responsible parts, the steel is first forged to level the structure and remove voids, then annealed to reduce strength and brittleness, and then subjected to temperature hardening to obtain maximum strength for this alloy. After the complete hardening, the steel is lightly annealed to slightly reduce the strength and eliminate the brittleness effect.
