Ruukki expands its range of Ramor protection steels with Ramor 550 grade, designed for ballistic protection. Ramor 550 is six times harder and stronger than mild steel and is suitable for applications requiring protection against explosions or ballistic threats, including armored vehicles, military vehicles and equipment, safe rooms, and other applications where structural weight savings is required without compromising protection properties. Ramor protection steels combine ballistic properties and direct-quenching technology to achieve hardness and high strength. Steels offer improved surface quality, flatness, and dimensional accuracy along with cutting, bending, and welding properties. Ramor 550 features good workability and can be welded using conventional welding technology and methods.
