The versatility of AISI 8620 bars makes them indispensable in sectors where failure is not an option. You will commonly find them used in the production of high-strength gears, pinions, and shafts within the automotive and aerospace industries. They are also the material of choice for crankshafts and other heavily loaded components in machinery, where their ability to be case-hardened creates a wear-resistant surface over a tough, shock-absorbing core, ensuring both durability and long service life.
