This type of steel mainly ensures its mechanical properties, so its grade reflects its mechanical properties, represented by Q+numbers, where "Q" is the initial Chinese pinyin of the yield point "Qu", and the number represents the yield point value. For example, Q275 represents the yield point of 275MPa. If the letters A, B, C, and D are marked after the grade, it indicates that the quality level of the steel is different, and the amount of S and P decreases in sequence, while the quality of the steel increases in sequence. If the letter "F" is marked after the grade, it is boiling steel; if "b" is semi killed steel; if "F," or "b" is not marked, it is killed steel. For example, Q235-A · F represents A-grade boiling steel with a yield point of 235MPa, and Q235-c represents c-grade killed steel with a yield point of 235MPa.
