S275JR HEA100 h shaped beam and S355J2 HEA100 h shaped steel beam
S275JR HEA100 and S355J2 HEA100 are both European standard hot-rolled H-beams, where "HEA100" represents the specific H-beam specification, while "S275JR" and "S355J2" represent the material of the steel.
Yield strength
The standard value of yield strength of S275JR h shaped beam HEA100 is 275MPa, which means that the steel will produce elastic deformation when the force does not reach this value, and it can return to its original state after unloading.
The standard value of yield strength of S355J2 HEA100 is 355MPa, which is significantly higher than S275JR HEA100 and can withstand greater stress without plastic deformation.
Tensile strength
The tensile strength of S275JR h shaped iron beam HEA100 is usually between 410 and 560MPa.
S355J2 HEA100 has a tensile strength range of 470-630MPa, with stronger tensile strength and can withstand greater tensile forces without breaking.
Impact toughness
S275JR only guarantees impact toughness at 20°C.
S355J2 can guarantee impact toughness at -20°C, which means that it can still maintain good toughness and impact resistance in low temperature environments, and is suitable for more severe environments and structures with higher toughness requirements.
Application scenarios
S275JR HEA100 h type beam: Suitable for general building structures and projects that do not require particularly high strength, such as ordinary industrial plants, secondary load-bearing components of warehouses, small building frames, etc. These scenarios have relatively low requirements for the bearing capacity of steel. Using S275JR can meet engineering needs while reducing costs.
S355J2 HEA100 h type steel beam: Commonly used in important projects with high requirements for structural strength, stability and toughness, such as the main structure of high-rise buildings, large bridge support components, offshore platforms, low-temperature environment building structures, etc. In these scenarios, steel needs to withstand large loads, complex stress states and harsh environmental conditions, and S355J2 can better meet the requirements.
