EN 10025-3 S355NL Wind power flanges
We are a professional manufacturer of EN 10025-3 S355NL Wind power flanges,EN10025 S355NL Forged Ring Flange in China
What is S355NL ?
S355NL is an alloy structural steel plate, “S” represents that it is a structural steel, “355” represents the yield strength of this steel grade, “N” represents the delivery status of the steel plate (normalized or normalized rolled), and “L” refers to low temerature,represents the impact of the steel not less than – 50 degrees.
S355NL Chemical composition
| Nominal thickness =< 63(mm) CEV max = 0.43 For long products the P and S content can be 0.005% higher For railway application a maximum S content of 0.01% may be agreed at the time of enquiry and order In sufficient other N-binding elements are present the minimum total Al content does not applay Cu content above 0.4% may cause hot shortness during hot forming |
| C | Si | Mn | Ni | P | S | Cr | Mo | V | N | Nb | Ti | Al | Cu | CEV |
| max 0.18 | max 0.5 | 0.9 – 1.65 | max 0.5 | max 0.025 | max 0.02 | max 0.3 | max 0.1 | max 0.12 | max 0.015 | max 0.05 | max 0.05 | max 0.02 | max 0.55 | max 0.45 |

Applications of S355JL Flanges
- Oil & Gas: Flanges for pipelines, offshore platforms, and refineries.
- Power Plants: Turbine assemblies, pressure vessels, and boiler systems.
- Chemical and Petrochemical Industries: Heat exchangers, reactors, and process equipment.
- Marine Engineering: Shipbuilding and subsea applications.
- Construction: Heavy-duty structural connections in bridges, cranes, and industrial frameworks.
The S355JL flange is a high-strength, structural steel flange designed for critical applications requiring exceptional mechanical properties and toughness at low temperatures.
Our S355JL wind flanges have the strength to support and join your tower sections, and are built to last throughout the life expectancy of the generator.
