Abstract
Ballistic helmets are essential for protecting against projectiles, fragmentation, and blunt trauma—key contributors to combat fatalities. This study compares the ballistic performance, durability, and cost-efficiency of a tempered martensite steel helmet to a modern Kevlar composite helmet. Through ballistic, mechanical, and metallographic testing, the steel helmet demonstrated comparable protection against pistol and revolver calibers, due to ballistic shape and high quality of steel applied. However, against rifle calibers, both helmets performed similarly, with perforations by 5.56x45 mm and 7.62x39 mm. The paper examines the trade-offs between protection, durability, and cost, highlighting steel helmets as a viable alternative in contemporary protective gear.
