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
