Steel Ball for Industry
The steel balls for Industry we produced are used in many industrial applications , where their properties of high capacity and fine surface finish are required. Theyare actually an alloy steel ball which owes its enhanced properties to the presence of lager proportions of special alloying elements such as chrominum, manganese and silicon than are ordinarily present in carbon steel.Due to through hardening, it has an excellent surface quality , superior wear resistance ,hard hardness and high load bearing capacity.
