    Classification Method of Q345B Seamless Steel Pipe

    Oct 17, 2019 · Q345B is a material for steel pipes. Q represents the yield of this material, and the back 345 refers to the yield value of this material. The Q345B steel pipe is a 16Mn steel pipe, which is one of the seamless steel pipe products. 16Mn is a material in steel. A name for steel in the past. Now called the law:Q345B. 16Mn is a low-alloy steel series. Comparison Of Q345AQ345BQ345C - World Iron&SteelDec 12, 2019 · Q345 low alloy high strength steel is the replacement steel of old GB grade 12MnV, 14MnNb, 18Nb, 16MnRE, 16Mn, etc. The chemical element is similar to 16Mn, and Q345 increases the micro-alloy element V, Ti and Nb which refines the grain, greatly improving the toughness and comprehensive mechanical properties of steel, thus allows a greater thickness. GB/T 8162 q345b q420d low alloy high strength structural GB/T 8162 specifies the dimensions, technical requirements, test methods and inspection rules of seamless steel tubes for low-alloy high-strength structural steel tubes, high-quality carbon structural steel tubes and alloy structural steel tubes.Would you like to know more about these steel pipes including manufacturing methods, delivery status, prices and freight charges?Just contact us and

    New China Standard-Q345B Changed to Q355B

    As we all know, China's steel production is the largest variety of rebar, followed by steel plate and sheet, and the largest percent of steel grade produced in the plate is Q235B, followed by Q345B. The 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. Q195B Q345B Cold Rolled Steel Strip Sino EastThe area of Sino East Steel Group is about 60,000 square meters with annual steel production capacity reaching to 500,000 MT. Its products ranges include steel pipes, tubes, steel sheet and coil, structural steel like steel profile and so on. Q345 Steel, Q345A Q345B Q345C Q345D Q345E Equivalent Dec 08, 2019 · Q345 Steel Properties Q345 steel is a Chinese GB standard Low Alloy High Strength Structural Steel, material density is 7.85 g/cm3, tensile strength is 470-630 Mpa, and yield strength is 345 MPa, it has better properties than Q235. According to GB/T 1591 2008, Q345 material has 5 quality grades:Q345A, Q345B, Q345C, Q345D and Q345E.
