Product Description
EN 10253-1 S235 Carbon Steel Tee
EN 10253-1 is a European standard for butt-welding pipe fittings made of non-alloy steel. Grade S235 in this standard is aligned with the familiar structural steel grade S235 (similar to EN 10025), making it a mild, low-carbon steel with well-established properties.
Chemical Composition
While EN 10253-1 includes several options and subgrades (such as P235 vs S235 and different impact property options), the typical chemical composition limits for S235 are as follows:
Element Composition Limit (mass %)
Carbon (C) max. 0.17-0.20%
Manganese (Mn) up to approx. 1.40%
Silicon (Si) ≤ 0.35% (often not strictly specified)
Phosphorus (P) max. 0.035%
Sulfur (S) max. 0.035%
Nitrogen (N) max. 0.012-0.014% (if specified)
Copper (Cu) max. 0.55% (if copper content is limited)
Important Considerations
  • Exact composition values depend on the specific subgrade and thickness range, with potential variations for thicker fittings
  • Manufacturing processes (such as killed steel with fine grain practice) may introduce controlled additions of aluminum, niobium, vanadium, or titanium, though these are limited and controlled rather than primary alloying elements
Certification Note: For certification, approvals, or design calculations, always consult the actual EN 10253-1 standard text (latest edition) and the material test certificate (MTC / 3.1 certificate) from the manufacturer to obtain precise chemical composition limits and measured values for your specific batch.
