Shot peening is a means of cold working the surface of metal parts by means of hail or blast of round metal shot directed against surface. The impact on the surface will indent the surface metal surface causing the plastic flow and work hardening the surface metal. The hardening of the surface increases its tensile strength and yield point. To learn about shot peening Erie PA should be the place to prioritize.
This technique is very useful in the metal industry. The main benefit is that it prevents fatigue failure is metal by strengthening its surface. Peening is a relatively new technique although it existed is other forms. To understand what happens during the process it is good that one goes back in history. This process is simply a renovation of a very ancient art.
The earliest features of cold working included hammering which was referred to as hammer hardening. It was used in ancient Greek to harden arrow and spear heads. The arrow and spear heads used to be strong such that they could pierce an animal without any troubles. They also used this procedure to create body armors which they used during times of war. It is believed that they has strong body armor which had the ability to bend spears and arrows from the enemy.
Today metallurgists are using sophisticated methods to improve the surfaces even more. Technology has made it possible for them to calculate and establish an increase in the strength and hardness. This has made it able for them to establish a percentage that can give the best results. They are now able to produce metals that are of standard size with quality control but still assures good reproduction.
Peening can be achieved using various types of shot. Peening shots may be bought from several companies dealing in these products. One must be careful when buying to ensure that they do not end up with a low quality product. One must ensure it is of definite screened size and well rounded. Its hardness must be equivalent of exceed that of the metal that is peened.
Those are just few considerations when one is buying a shot. Some of the types of shots include a steel shot. It is effective as far as the skyrocketing fatigue strength is considered. Steel shots are more expensive than chilled iron shots. Chilled iron shots present a major disadvantage that has to do with separation problem. This is due to the fact that peening specifications require that a broken shot be separated and eliminated from the peening shot.
Another type is the cur wire shot which is basically another material used for peening. It is manufactured by clipping off short lengths of steel wire. Peening specifications require that this type of shot be blasted against the scrap steel until it becomes rounded. This process is very time consuming and it decreases the life span of the shot.
The fatigue life cycle of stressed parts can be increased by the use of peening. This procedure is helpful in making parts straight. It can also be applied in different areas like eliminating fret corrosion and prevention of stress corrosion crack.
