S355JR HR plate adopts a new nano precipitation strengthening technology, which achieves the optimal balance between strength and toughness by precisely controlling the precipitation phase of niobium titanium carbonitride. Its dynamic recrystallization process breaks through traditional limitations in grain size and achieves ASTM grade 12 or higher.
The innovative application of hydrogen trap element design in this product controls the diffusion hydrogen content below 1.5ppm, significantly improving the welding cold crack resistance. The digital twin quality system ensures that the performance fluctuation of each batch is ≤ 3%.
As a representative of the fourth generation TMCP technology, S355JR steel HR plate has been successfully applied to multiple seismic nodes of super high-rise buildings, with a 40% improvement in cyclic loading performance compared to conventional products, and has obtained CNAS laboratory certification.
