European Corrosion Resistant Steel Grades
Steel grades form the foundation of steel production and, as such, are an integral part of any industry. In Europe the most commonly used steel grades are the European Corrosion Resistant Steel Grades (ECR). These steel grades were developed by European steelmakers over a period of time to meet the unique needs of their customers. Each grade offers specific advantages and is suited to particular applications, allowing engineers to make informed decisions when selecting the right steel grade for their requirements.
The European Corrosion Resistant Steel Grades include:
Grade S235JRH - This grade is an evolution of the S235 grade and offers enhanced corrosion resistance thanks to its carbon and manganese content. While it is not as corrosion-resistant as other grades, its low cost and good weldability make it a popular choice for many structural steel applications.
Grade S355J2H - Unlike its predecessor S355J2H offers improved resistance against corrosion due to its increase in carbon, phosphorous and sulphur content. It is suitable for use in environments with high humidity and is very well suited for making welded tubular products.
Grade S420NL - S420NL has a higher carbon content compared to its predecessor S420 and features good weldability as well as alloying properties. It’s also highly resistant to corrosion and allows for a very good welding connection between components.
Grade S460NL - This grade is an evolution of S460N and offers superior levels of corrosion resistance due to its higher levels of sulphur and nitrogen content. It is ideal for applications that require increased levels of strength such as large welded structures, high pressure vessels and storage tanks.
Grade P460NL2 - This grade is an evolution of P460NL with improved corrosion resistance due to its higher levels of manganese and phosphorus content. It also retains its superior weldability making it suitable for use in applications such as pipelines and pressure vessels.
Grade 16Mo3 - 16Mo3 is a fine grained steel grade and offers comparatively better levels of corrosion resistance compared to S355 and S420. It’s good for welded applications such as boilers, heat exchangers and pressure vessels.
To choose the right grade of European Corrosion Resistant Steel for an application, engineers should consider a range of parameters such as strength, weldability, cost and corrosion resistance. By taking into account these variables, engineers can make an informed decision as to which grade is best suited for the job.
In summary, the European Corrosion Resistant Steel Grades are an important part of any industry. Each grade offers a unique set of characteristics making it ideal for different types of applications. By considering the various factors engineers can determine which grade is most suitable for the application. When selecting the right grade, engineers should always consider cost, strength, weldability and corrosion resistance.
