S355J2+N round bar is a high strength steel grade widely used in industries for its versatility. It belongs to the S355 steel group known for its tensile and yield strengths making it adaptable for applications. The "+" designation in S355J2+N indicates its suitability for forming.
Typically the chemical composition of S355J2+N includes elements like manganese, carbon, silicon, sulfur, phosphorus, nitrogen and soluble aluminum. Each element contributes properties that result in a balanced product with strength, weldability, ductility and excellent impact resistance even at low temperatures.
The cylindrical shape of this bar variant of S355J2+N steel ensures a distribution of forces across the material. This makes it ideal for applications requiring resistance. Industries such as machine building and construction extensively use S355J2+N bars in components like shafts, rods and pins that demand robustness and durability.
One notable advantage of the S355J2+N round bar is its weldability. This particular feature is highly valuable in industries where intricate structures and components are built as these often involve welding and handling. This facilitates manufacturing and upkeep leading to cost savings in the term.
Moreover the advantageous combination of characteristics offered by the S355J2+N round bar ranging from its resilience to its ease of machining positions it as a favored option for engineers and architects. Its comprehensive approach to strength and longevity aligned with sustainability establishes it as an ideal selection in our pursuit of effective and sustainable steel production.
