What do "Q" and "235" in the steel grade Q235 represent respectively?

"Q" is the first letter of the pinyin of "Qu" in "yield strength", representing yield strength; "235" indicates that the minimum yield strength of the steel is 235MPa (megapascal). Q235 is a commonly used carbon structural steel grade in China, with good plasticity, toughness and weldability. Many building profiles supplied by Xiamen Xinghuibin adopt this grade of steel, which is suitable for general load-bearing structures.
