Performance comparison of 254x254x167 structural steel universal column
S355JR h-shaped iron beam: tensile strength is usually 470-630MPa, yield strength is 355MPa. When doing + 20℃ impact test, the impact energy requirement is not less than 27 kJ.
It has good impact toughness at room temperature and can withstand a certain degree of impact and vibration, but the toughness will be reduced in low temperature environment.
S355J0 h-shaped beam: tensile strength is usually 470-630MPa, yield strength is 355MPa. The impact energy test temperature is 0℃, and it can still maintain good impact toughness at 0℃. Compared with S355JR, it is more suitable for use in low temperature environments.
254x254x167 h-shaped steel processing and welding performance
