Introduction

S355JR is a type of low alloy high strength structural steel. The letter "S" indicates that it is belong to structural steel; "355" represent its minimum yield strength is 355Mpa, which means that it is not easy to undergo plasticity deformation when subjected to external forces. The letter "JR" indicates that its impact toughness, the impact test is usually undergone at a temperature of 20℃. The chemical composition of S355JR is precisely controlled, mainly including elements such as carbon (C), silicon (Si), manganese (Mn), phosphorus (P), sulfur (S), etc. The reasonable ratio of these elements endows S355JR steel with high strength, good toughness, and excellent mechanical properties.

S355JR H section steel is made through hot rolled process. Hot rolled H section steel has good surface quality , uniform internal organized structure. The surface quality of the hot rolled H section steel is good, and the internal structure is uniform. In order to improve the mechanical properties of H section steel, H section steel will undergo normalizing treatment before delivery.
