The steel retains its austenite structure and has high toughness after rapid quenching in water (also known as water toughening treatment). Its hardness is quite low (170-230HB), which allows it to undergo plastic deformation when its surface is impacted. As a result of deformation strengthening, work hardening occurs in the deformed layer of …

The value obtained in Steel B doubles Steel C and this difference can be attributed to the low yield stress in ε ε Steel C. Bouaziz pointed out that yield stress induced by solid solution hardening is greatly increased with carbon content [21], and this could be the primary cause of a higher value α' of Steel B than Steel C, which even has ...
This steel is a non-magnetic austenitic type, supplied in full plates or as profiled pieces by plasma cutting. Suitable for wear applications where high impact/gouging abrasion leads to a work hardening effect. High manganese steel plate becomes increasingly hard when the surfaces of components are subject to repeated impact or abrasion.
