The material addressed in this research is stainless steel 2169, a 200 series stainless steel which has so far found applications in aviation, demolition, motor-vehicle design and nuclear reactor containment. Longitudinal and lateral stresses during the shock loading of 2169 have been measured using manganin stress gauges. The shear strength has been shown to increase with impact stress and it is seen that when compared with another common austenitic stainless steel (304L) the initial HEL is greater, but that 2169 has a lesser degree of hardening with increased impact stress. The results are discussed in terms of structure and degree of alloying.
