According to GB/T 1591 2008, Q345 material has 5 quality grades:Q345A, Q345B, Q345C, Q345D and Q345B Flat Steel Bar Crane Rail Manufacturer - Steel Rail Standard:GB/T1591-2008 Grade:Q345B Main Size for crane rail application:See the table below. We could also arrange production according to customers required size.
Q355 Steel (Q355B Q355C Q355D) Q355 steel is a Chinese low alloy high strength structural steel, which replaced Q345, the material density is 7.85 g/cm3. According to GB/T 1591 -2018, Q355 has 3 quality levels:Q355B, Q355C and Q355D. Q is the first letter of Chinese Pinyin:qu fu dian, which means Yield Strength, 355 is the What is GB T1591 Q345B steel equivalent ASTM - Bebon SteelGB T1591 Q345B steel is Chinese low alloy high strength steel. The low alloy high strength steel has wide application in the world. In ASTM standard, there is also low alloy high strength steel, and the most widely used among them is ASTM A572 Gr 50 steel, which is New China Standard-Q345B Changed to Q355BThe biggest impact of the new GB/T 1591-2018 release is Q345B, because the output of other grades has little effect. According to what we said above, this change is in line with international standards. It can be told from the brand name, it is obviously in line with the European standard.
