Fine grain structural steel tube S275J0H S275J2H pipe properties

Performance advantages brought by fine grains
The S275J0H and S275J2H steel pipes with fine grain structure exhibit excellent performance due to their unique fine grain structure. Fine grains increase grain boundaries, effectively hinder dislocation movement, enhance steel strength and hardness, and lay a solid foundation for its application in complex working conditions.

Performance difference between S275J0H and S275J2H pipe
In the 0 ℃ impact test, the impact energy of steel tube S275J0H can reach 27J. In terms of yield strength, when the wall thickness is between 3-16mm, ≥ 275MPa, ≥ 265MPa at 16-40mm, tensile strength is between 410-560MPa. The steel tube S275J2H can maintain an impact energy of 27J in the -20℃ impact test, with a yield strength similar to that of the S275J0H pipe. Its advantages are more pronounced when used in low-temperature environments.

Widely used performance support
Based on the above performance, S275J0H and S275J2H pipes are used in the construction field to build stable structural frameworks. S275J2H steel tube stands out in cold regions such as outdoor facility construction in the north due to its impact toughness at lower temperatures, meeting the stringent requirements for pipe performance in different scenarios.
