Product Description
SAW Longitudinally Welded Hollow Section Pipes for Fixed Offshore Structures
High-performance longitudinally welded hollow section pipes manufactured to EN10225 S355G8+N (steel no 1.8810+N) and API5L X52N PSL2 (MOD) specifications, specifically engineered for demanding fixed offshore structural applications.
1.8810 Steel Overview
1.8810 steel is a standardized European tool steel grade (EN/DIN system) specifically designed for applications requiring exceptional wear resistance and toughness. This high-performance material is ideal for cutting tools, cold work applications, and components subjected to significant mechanical stress.
Chemical Composition
Typical composition by weight percentage:
Element Composition
Carbon (C) 0.90–1.05%
Chromium (Cr) 0.40–0.60%
Manganese (Mn) 1.00–1.30%
Silicon (Si) 0.10–0.40%
Vanadium (V) 0.10–0.20%
Phosphorus (P) ≤ 0.030%
Sulfur (S) ≤ 0.030%
Composition Benefits
High Carbon Content (0.90–1.05%):
  • Enables high hardness after heat treatment
  • Provides excellent edge retention and wear resistance
  • Ideal for cutting tools, punches, and precision components
Chromium (0.40–0.60%):
  • Enhances hardenability and wear resistance
  • Improves corrosion resistance compared to plain carbon steels
Manganese (1.00–1.30%):
  • Improves toughness and hardenability
  • Assists in deoxidation during steel production
Silicon (0.10–0.40%):
  • Functions as a deoxidizing agent
  • Contributes to overall strength enhancement
Vanadium (0.10–0.20%):
  • Refines grain structure for improved toughness
  • Enhances wear resistance and edge stability
Material Selection Guidance
When selecting 1.8810 steel for your project, you're choosing a high-carbon, alloyed tool steel capable of achieving high hardness levels while maintaining excellent toughness. This makes it particularly suitable for:
  • Precision cutting tools
  • Cold working applications
  • Wear-resistant components
  • Structural elements requiring durability
Important: Always verify the exact specification sheet or datasheet from your steel supplier, as slight composition limits may vary by standard or manufacturer.
