The weapons and armament sector concentrates the most severe constraints in mechanical industry: extreme thermo-mechanical fatigue on gun barrels (firing cycles at several thousand bars, temperatures > 1000 °C), long-duration storage corrosion on munitions (10–30 years in arsenals), absolute reliability on weapon systems across varied operational environments (desert, arctic, marine, altitude).
Kronos Engineering supports major defense primes — Nexter, MBDA, Thales LAS, Rheinmetall, KMW, Raytheon, BAE Systems Land, Leonardo DRS — on the special processes that improve service life and reliability: high-intensity shot peening, roto peening (gun barrels, chambers), cold working (breech joints, sleeves), precision boring (bore rework after ballistic wear), HFMI (fatigue welds), flapper peening (artillery parts in maintenance).
