Ultra high-hardness steel (600 HB) for ballistic protection

Mars 600 is an ultra high hard armor steel (600 HB) having both very high ballistic performances and integration possibilities similar to those of structural materials.

Mars 600 is an innovative product from the Center Materials Research of Le Creusot, and Bozhong rich expertise for over a quarter century on modern 600 HB materials.

Mars 600 is a multipurpose 600HB with an impressive ballistic behavior in terms of deformation capacity, resistance to multi-impacts with workability (mainly bending) close to a 500HB steel.

Mars 600 is the material of the future that will change designs meeting both light weight and integration requirements of manufacturers. Its greats properties suggest unlimited of use possibilities.
