a. The deoxidation method is designated as follows: FF: Fully killed steel containing nitrogen binding elements in amounts sufficient to bind available nitrogen (e.g. min. 0,020 % total Al or 0,015 % soluble Al). b. The maximum value for nitrogen does not apply if the chemical composition shows a minimum total Al content of 0,020 % with a minimum Al/N ratio of 2:1, or if sufficient other N-binding elements are present. The N-binding elements shall be recorded in the Inspection Document.

Hydrostatic Test

Each length of pipe shall be tested by the manufacturer to a hydrostatic pressure that will produce in the pipe wall a stress of not less than 60% of the specified minimum yield strength at room temperature. The pressure shall be determined by the following equation:
P=2St/D

Permissible Variations In Weights and Dimensions

Each length of pipe shall be weighed separately and its weight shall not vary more than 10% over or 5.5% under its theoretical weight, calculated using its length and its weight per unit length
The outside diameter shall not vary more than ±1% from the specified nominal outside diameter
Wall thickness at any point shall not more than 12.5% under the specified wall thickness

Product advantage

One of the main advantages of S235JRH steel is its excellent weldability, making it ideal for a variety of construction applications. Its cold-formable properties allow it to have precise dimensions and smooth surfaces that can enhance the beauty of the structure.

In addition, the material has good tensile strength and ductility, providing the necessary support for load-bearing applications.

Product Shortcoming

While S235JRH is suitable for many structural applications, it may not perform as well in extreme temperatures or corrosive conditions. Its mechanical properties may be affected by these factors, potentially resulting in reduced durability over time.

The reliance on a cold forming process may limit the thickness of the parts produced, which can be a disadvantage for certain heavy-duty applications.
