Usage and Applications of Alloy Steel For Bearing

Alloy steel is used in making all kinds of bearing ring and rolling elements, like combustion engine, machine tool, and bearings for melting machine; also used for making tools and measuring tools.

Bearing steels are used for ball and roller bearing applications and are comprised of low carbon steels and high carbon through harden able steel.

Alloy Steel can be used in machine parts and engineering components.

Applications range: Chemical fertilizer pipe, building, machinery, textile industry, etc
