S355JR+N is a non-alloy structural steel which is characterized by its even mechanical properties and good workability. It usually comprises ≤0.24% Carbon, ≤1.6% Manganese, ≤0.035% Phosphorus, and ≤0.035% Sulfur. The “+N“ marking refers to normalized steel, which makes it tougher and more mechanically uniform. It has a minimum yield point of 355 MPa and tensile strength of 470–630 MPa, with good elongation and low-temperature impact properties. Its high weldability and machinability make it a leading candidate for structural fabrication and applications where strength and elasticity are both required.
