Abstract

Disclosed is a shot ball having excellent strength and wear resistance. The shot ball according to an embodiment of the present invention comprises, in terms of weight%, 0.09-1.3% of carbon (C), 3-29%of manganese (Mn), 1.0-8.0% of chrome (Cr), 0.05% or less of phosphorus (P), 0.05% or less of sulfur (S), 10% or less (excluding 0) of nickel (Ni), 7% or less (excluding 0) of molybdenum (Mo), 10% orless (excluding 0) of tungsten (W), and the remainder iron (Fe) and other unavoidable impurities.

Description

technical field [0001] The present disclosure relates to shot balls (ie, shot blasting shots) and methods of manufacturing the same, and more particularly to shot balls used in shot blasting machines for surface modification and methods of manufacturing the same. Background technique [0002] Shot peening for surface modification is by spraying pellets stored in a hopper onto the strip under high pressure so that the pellets sprayed under high pressure collide with the strip to mechanically remove the existing particles on the surface of the strip. A method of cleaning and finishing the surface of the strip by removing scale, rust, coating, etc. Shot peening requires a shorter working time than grit blasting using sand. [0003] For this purpose, materials such as cast iron and stainless steel are used to manufacture the pellets. In particular, the pellets are usually formed of hard tissue in order to improve wear resistance. [0004] However, pellets are damaged when use...
