Here we will introduce some commonly used steel codes of Chinese GB standards and the equivalent materials on other standards.
GB standards are the Chinese national standards, which is an abbreviation of Guojia Biaozhun. Currently, there are two standards for expressing steel grades, namely GB/T 221-2008 and GB/T 17616-2013. Generally, the steel grades are represented by capitalized Chinese pinyin letters, chemical element symbols, and Arabic numerals to indicate the name, use, characteristics, and process of steel products. For example, carbon steel is represented by “Q+number+quality grade”. Q here represents the yield point of the steel, and the following number represents the yield point value in MPa. And the quality grade is represented by A, B, C, and D respectively. For example, Q235 represents carbon steel with a yield point of 235 MPa.
