Finnish armour specialist Ruukki Metals is showcasing its latest steel product for armoured vehicles. Produced using the company-developed direct quenching process, Ramor 450 can be used to provide a lightweight frame structure or as a separate floor shield for protection against mines. Direct quenching produces steels that can be up to six times harder than normal structural steel, while also providing a high surface quality and flatness.
Ramor 450 builds on the properties of Ramor 400, offering excellent protection against the high pressures associated with explosive blasts, but with added guarantees for mechanical yield and tensile strength. Ramor 450 is guaranteed to have a bending radius four times that of its thickness.
Ruukki (Hall 5, Stand G751) also produces Ramor 500 and 550 steels, which are optimised for protection against kinetic energy projectiles.
