According to its yield strength grade is divided into five grades, the commonly used grade of steel structure is Q235 steel. The grade of steel is composed of four parts in order, such as the letter representing the yield point, the yield point value, the quality grade symbol, and the deoxidation method symbol. Such as Q235AF, where "Q 'is the first letter of the Chinese phonetic alphabet of the steel yield point" Qu "word; 235" is the yield point value of the grade steel, indicating that the yield strength of the steel is "235N/MM";" "A" is the quality grade symbol of steel, which is divided into four grades: A,B,C and D;" A" grade is the lowest grade and D" grade is the highest grade;" F "is the first letter of the Chinese pinyin" boiling "character of boiling steel, indicating that the steel is boiling steel. If the letter "B" is marked at the end of the steel grade, it indicates that the steel is semi-killed steel, and" B" is the first letter of the Chinese pinyin of the "half" character of the semi-killed steel; The "Z" letter is the first letter of the Chinese pinyin of the "town" character of sedative steel, representing sedative steel; The letter "TZ" is the first letter of the Chinese pinyin of the special sedative steel "special Zhen", representing the special sedative steel. In the method of steel grade composition, the symbols "Z" and "TZ" are omitted, and the four symbols "F ", "B"," Z "and" TZ "indicate the degree of deoxidation when the ingot is cast. Killed steel is fully deoxidized steel such as aluminum and silicon, which emits less gas during casting and has good quality, but is expensive. Boiling steel is deoxidized with ferromanganese, due to insufficient deoxidization, there is boiling phenomenon in the ingot when casting, the quality is not uniform, but the productivity is higher. Between the killed steel and the boiling steel is the semi-killed steel.
