Hardox 450 Steel Plate

Description

Product Description Hardox 450 Steel Plate

Hardox 450 is part of the Hardox wear plate series, produced by SSAB, a Swedish steel company renowned for its innovative steel solutions. It is a quenched and tempered steel plate with a nominal hardness of 450 HBW (Brinell Hardness). This hardness and impressive toughness make Hardox 450 an ideal material for heavy-duty applications that demand high wear resistance.

Key Properties of Hardox 450 Steel Plate

1. Abrasion Resistance: Hardox 450 is engineered to withstand severe wear and tear. Its high hardness ensures excellent resistance to abrasion, prolonging the lifespan of components.
2. Toughness: Despite its hardness, Hardox 450 exhibits remarkable toughness. This property allows it to endure heavy impacts without cracking, making it suitable for demanding environments.
3. High Strength: Hardox 450 offers exceptional yield and tensile strength, enabling it to handle heavy loads without deformation.
4. Weldability: Unlike many high-hardness steels, Hardox 450 maintains good weldability. It can be welded using standard welding methods, provided the correct preheating and post-welding practices are followed.
5. Machinability: Although it is harder than conventional steel, Hardox 450 can be machined with proper tools and techniques.
6. Flatness and Surface Quality: Hardox 450’s tight flatness tolerances and superior surface quality enhance its performance in various applications

Fabrication and Processing

1. Cutting: Hardox 450 can be cut using thermal cutting methods such as oxy-fuel, plasma, or laser cutting. Mechanical cutting, such as shearing, is also possible but requires proper tooling.
2. Welding:
   • Preheating is recommended for thicker plates to prevent cracking.
   • Use low-hydrogen electrodes or wires to minimize hydrogen-induced cracking.
   • Proper post-welding cooling practices ensure optimal results.
3. Bending: Hardox 450 can be cold-formed, provided the bending radius is within recommended limits. Using the correct tooling and techniques is essential to avoid cracking.
4. Machining:
   • Carbide tools are recommended for machining Hardox 450.
   • Lower cutting speeds and higher feed rates improve tool life.
