S275JR, S275J0, S275J2 steel plate meaning

1. The European standard S275JR carbon steel plate is similar to the steel grades listed in China GB/T 700 and GB/T 1591. It is also carbon structural steel and low-alloy structural steel for engineering and structural use, and is usually delivered without heat treatment. In fact, S185 is equivalent to China's Q195; S235 and S275 are equivalent to China's Q235 and Q275; S355 is equivalent to China's Q345. Except for S185, 20℃, 0℃, -20℃ impact energy tests are required.

2. S275J0 is a European standard low-alloy steel plate, which is equivalent to domestic Q345B. Implement EN10025 standard. S275JR, S275J0, S275J2 steel plates are commonly used in the construction of workshops, general buildings and various construction machinery, such as excavators, loaders, bulldozers, coal mine hydraulic supports, etc.

3. The difference between S275JR, S275J0, S275J2 steel plate is that the impact temperature is different, and the chemical composition is also different. S represents structural steel; 275 represents the yield strength value: 275MPa; J2 refers to the impact energy test temperature of -20 degrees Celsius; JR refers to the impact energy test temperature of 20 degrees Celsius; J0 refers to the impact energy test temperature of 0 degrees Celsius.
