Weldox 450 Sheets & Plates

What are Weldox 450 Sheets & Plates?

Weldox 450 is a high-strength structural steel with a minimum yield strength of 450 MPa, offering excellent weldability, good formability, and superior toughness. It is widely used in applications requiring higher strength than standard structural steels.

Key Functions:

• Provide enhanced strength for structural applications
• Improve load-bearing capacity
• Offer excellent weldability and fabrication
• Ensure durability in harsh working conditions

Chemical Composition of Weldox 450

Typical Composition:

• Carbon (C): ≤ 0.20%
• Manganese (Mn): ≤ 1.60%
• Silicon (Si): ≤ 0.50%
• Phosphorus (P): ≤ 0.025%
• Sulfur (S): ≤ 0.010%
• Alloying Elements: Micro-alloyed for strength and toughness

The controlled composition ensures an optimal balance between strength, toughness, and weldability.
