What is the Difference Between Shot Blasting and Shot ...

The biggest difference between shot blasting and shot peening is the end result. Shot blasting uses abrasives to clean or smooth the surface to prepare it for processing; shot peening uses the plasticity of metal to prolong the life of the part. In shot peening, each shot acts as a ball-peen hammer. The process makes the surface of the metal ...

Slide 1

Shot peening is a cold working process that imparts a small indentation on the surface of a part by impacting small spheres called shot onto the material surface. (Figure 3) This process creates the same effect that a peening hammer does by causing outer surface to yield in tension.

Shot peening - Wikipedia

Shot peening is a cold working process used to produce a compressive residual stress layer and modify mechanical properties of metals and composites. It entails impacting a surface with shot (round metallic, glass, or ceramic particles) with force sufficient to create plastic deformation.. In machining, shot peening is used to strengthen and relieve stress in components like steel automobile ...

Aug 16, 2016· The increase in roughness inherent during shot peening must always be considered as negative thing The depth of the compressive layer depends on the intensity and the hardness of the reworkedpart. shot Peening process: As we mentioned before we do the shot peening for machined or welded parts, so before we shot any part we do some tests on ...


Shot peening may also be used to enhance the surface finish of a component. It is known that the surface finish has considerable effect on fatigue strength and corrosion cracking resistance of alloys. To improve the surface finish a double shot peening operation may be required in which a heavy shot peening operation is followed by a micro-ball


on the mass loss in relation to the process parame-ters and parameters of the treated material and of the cleaning grain. The comparison is also made of the surface conditions (surface roughness). As regards shot peening, it is required that the stream of shots should be well concentrated so that the process should be restricted to local ...

The History of Shot Peening Peenable Materials How It Works

been achieved, Almen strips are mounted to Almen blocks and the shot peening process is performed on a scrap part. An Almen strip is a strip of SAE 1070 spring steel that, when peened on one side, it will deform into an arc towards the peened side due to the induced compressive stresses from the shot peening process.

In this paper, the effects of the process conditions for both single and double shot peening on the fatigue life of AISI 4340 low alloy steel is investigated. The fatigue tests revealed that the shot peening process could significantly enhance the fatigue life of the treated components.

FAQ: What is peening? - TWI

Peening is a cold working process in which the surface of the component is deliberately deformed, in the basic method, by hammering. During peening, the surface layer attempts to expand laterally but is prevented from doing so by the elastic nature of the sub-surface, bulk material.
