Home / Materials / Heat treatment of s355j2 n steel

S355J2N steel is a structural steel known for its excellent weldability, machinability, and high strength. The combination of numbers and letters in the name holds various meanings. Curious about what these mean and in which industries S355J2N steel is commonly used? And what challenges can arise with S355J2N steel? Read on and discover the value of S355J2N.

In which industries is s355J2 n steel frequently used?

S355J2+N is a type of structural steel composed of S (structural), 255 (minimum yield strength), J2 (indicating toughness), and N (normalized). Thanks to the favorable properties of this type of structural steel, it is used in various sectors. These primarily include mechanical engineering, shipbuilding, the offshore industry, and the construction sector.

The n for normalizing

So, the material s355j2 n steel is already normalized. But why is this done? It’s because of the following reasons:

  • Enhancement of Mechanical Properties: Apart from refining the grain structure, normalizing aids in homogenizing and enhancing mechanical properties such as tensile strength, yield strength, and toughness.
  • Improved Weldability: By normalizing S355j2 n, the steel becomes more homogeneous, resulting in enhanced weldability. This is crucial for construction applications where welding is often necessary.
  • Removal of Internal Stresses: Normalizing can assist in reducing internal stresses introduced during forging, rolling, or other shaping processes. Reducing these stresses can minimize the risk of distortion or cracking in the final product.

Normalizing S355j2 n steel, therefore, is a strategic choice to achieve the desired material properties. This is essential for the applications it’s intended for, especially in the construction and building sector.

What challenges can S355J2N steel present?

Although this type of steel has already undergone normalization, it can still undergo heat treatment. The choice of a specific treatment depends on the particular goal and desired properties. For example, various heat treatments can be chosen to remove stresses, change the microstructure, and increase hardness.
