Abstract
Explosive containment vessels (ECVs), such as those utilized to contain the detonation products of explosives during bomb/munition disposal or containment of experiments on explosive devices, are required to be fabricated from high-integrity materials to ensure the safety of people and/or property in the vicinity of the vessel. Candidate materials for ECV construction are desired to exhibit high strength and high toughness to prevent ductile exhaustion and/or brittle failure induced by impulsive loading; a non-trivial requirement given that, generally, materials exhibit poorer toughness with increasing strength. Additionally, vessel manufacturability (e.g. weldability and component thickness) also needs also to be considered when selecting materials for ECVs. Los Alamos National Laboratory has had success using both A723 and HSLA-100 steel alloys for ECV applications. The present article provides a background on these two alloys and compares them from the perspectives mentioned above. A723 is better suited for thick-section and non-welded applications, whereas HSLA-100 is better suited for thinner (< ~10 cm) vessel components but also supports welding without post-weld heat treatment. Discussion is included regarding how the effects from the alloy compositions of these two steels enables them to perform in complementary applications. This discussion is extended to current alloy development for ECVs which seeks to improve performance and manufacturability.
