Steel Shots

They are produced in two forms as low carbon steel and high carbon steel balls. Both
production are same, they are produced by melting scrap steel in induction furnaces and by cooling in water
after atomization. Only one difference among them is composition of scrap being used during production.
When used scraps having low carbon S (sulphur) and P (phosphor) during melting operation, the structure
forming after cooling will be bianitic. In this case, thermal processing also is not required.

During melting operation, when used scraps having high carbon, the structure forming
after cooling will be martensitic. In this case, thermal processing is required.

Steel balls are metallic structured abrasives of sandblasting using widely in many
sandblasting process. Steel balls produced from bianitic micro structure are bianitic and produced from
martensitic micro structure are martensitic steel balls.
