UB 178x102x19 203x102x23 S355JR Structural Steel
UB 178x102x19 h section steel: "UB" indicates a type of British standard H-shaped steel, 178 indicates that the height of the steel is about 178mm, 102 indicates that the flange width is about 102mm, and 19 indicates that the weight per meter is about 19kg.
UB 203x102x23 h shaped steel: 203 indicates that the height of the steel is about 203mm, the flange width is also 102mm, and the weight per meter is about 23kg.
In the name of S355JR structural h beam, "S" indicates structural steel, "355" indicates that the yield strength is 355MPa, and "JR" represents the impact energy of 27 joules at 20℃, which indicates that the steel can maintain good toughness even in low temperature environment.
The carbon content of S355JR h-shaped beam is controlled below 0.22% to ensure good weldability, manganese and silicon elements are used to improve the strength and hardness of the steel, and the content of phosphorus and sulfur is strictly controlled to avoid negative effects on the mechanical properties of the steel.
The steel yield strength of S355JR h-type beam is 355MPa, the tensile strength is 470-630MPa, and the elongation is 22%. Based on this material, these two types of steel have high strength and good toughness, can withstand certain pressure, tension and impact loads, and are suitable for a variety of engineering structures.
UB 178x102x19 203x102x23 h beam Features
High strength: can withstand large loads and can be used for structural parts with high strength requirements.
Good toughness: has good toughness at room temperature and certain low temperature conditions, is not prone to brittle fracture, and improves the safety of the structure.
UB 178x102x19 203x102x23 h section beam Application
Building structure: commonly used in building frame structure, steel structure factory, warehouse, etc.
Bridge engineering: can be used to build small bridges or certain structural components of bridges.
