Seamless Pipe and Hollow Sections for Fixed Offshore Structures
High-performance seamless pipes and hollow sections manufactured to EN10225 S355G15+N or Q&T (steel no 1.1190+N) and API5L X52 PSL2 (MOD) specifications, designed specifically for demanding offshore structural applications.
Material Specifications
1.1190 steel is a high-carbon, non-alloy tool steel commonly designated as C100U or equivalent to Ck101/C100. This material is engineered for applications requiring exceptional hardness and wear resistance.
Chemical Composition
Typical composition by weight percentage:
Element
Content (%)
Carbon (C)
0.95 – 1.05
Silicon (Si)
0.10 – 0.40
Manganese (Mn)
0.30 – 0.50
Phosphorus (P)
≤ 0.030
Sulfur (S)
≤ 0.030
Material Characteristics
High Carbon Content (~1% C)
Provides exceptional hardness and wear resistance after proper heat treatment, making it ideal for cutting tools, knives, measuring instruments, and springs where edge retention is critical.
Low Alloy Composition
Minimal silicon and manganese content for deoxidation and strength enhancement. Controlled phosphorus and sulfur levels ensure material cleanliness and improved toughness.
Heat Treatment Performance
• Achieves hardness up to 60 HRC after quenching and tempering
• Requires precise tempering to prevent brittleness
• Non-corrosive: Contains no chromium or stainless alloying elements
• Excellent machinability in annealed state with predictable heat treatment response
Application Notes
This steel composition offers a reliable, predictable solution for applications demanding high hardness and wear resistance. For precise composition verification and specific application requirements, always consult the manufacturer's mill certificate or technical datasheet.
