Q275 material is Chinese carbon structural steel, the first letter "Q" represents yield strength, "275 means" 275 Mpa. The min. yield strength of Q275 material is 275Mpa. In China, Q275 material is not that widely used as Q235 and Q345 steel. But it also has broad market in construction and heavy equipment industry. Q275 material is generally refer to Q275B steel, what is Q275 material equivalent steel grade in EN standard?
We know Q235 steel equivalent is S235, Q345 (Q355) steel equivalent is S355, it is not hard to know Q275 material equivalent steel grade in EN standard is S275, among which S275JR is most popular.
