E-52100 Aircraft Hot Rolled Spheroidize Annealed Alloy

This high carbon, high chromium alloy is produced by the electric furnace process and then vacuum degassed to meet the rigid standards of the aircraft industry for bearing applications. This steel develops high hardness and has exceptional resistance to wear and abrasion. In smaller sections it has high compressive strength. Because of high carbon content, bars are furnished in the spheroidize annealed condition in order to provide the best possible machinability.
