Product Description
1.1182 Steel Weldable Structural Steels for Fixed Offshore Structures Tubes
Conforms to EN10225 S355G13+N (steel no 1.1182+N)
Material Overview
1.1182 steel is a European (EN) designation for a medium-carbon, non-alloy steel primarily used for springs and components requiring excellent strength and wear resistance. In EN standards, it corresponds to grade C60E or C60R, depending on delivery condition.
Chemical Composition
Element Content Range
Carbon (C) 0.57 – 0.65 %
Silicon (Si) ≤ 0.40 % (typically 0.15 – 0.35 %)
Manganese (Mn) 0.60 – 0.90 %
Phosphorus (P) ≤ 0.035 %
Sulfur (S) ≤ 0.035 %
Key Composition Characteristics
Medium–High Carbon Content (≈0.6%) – Provides excellent hardness and strength after heat treatment, making it suitable for springs, wear parts, and tools requiring hard surfaces with reasonable toughness.
Manganese (0.6–0.9%) – Enhances hardenability and strength while assisting with deoxidation during steelmaking processes.
Low Phosphorus and Sulfur – Maintains steel cleanliness, improving overall toughness and fatigue resistance.
Ideal Applications
1.1182 steel is the optimal choice when your project requires:
  • Superior hardness and wear resistance compared to low-carbon steels
  • Compatibility with conventional heat treatment processes (quenching and tempering)
  • A widely available, standardized spring and tool steel within the EN system
