Comparison Of Q345AQ345BQ345C - World Iron&SteelDec 12, 2019 · Some foreign customers are often confused about GB Q345 steel. 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,
Q355B steel is a upgraded low alloy steel of grade Q345B. There are some differences between Q345B and Q355B steel. Q345B steel and Q355B steel differences in mechanical properties Q345B steel mechanical properties:Yield Strength requirement in different thickness:t16mm:345MPa; 16-40mm:335MPa; 40-63mm:325MPa; 63-80mm:315MPa; New China Standard-Q345B Changed to Q355BAs 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. Q345 Steel, Q345A Q345B Q345C Q345D Q345E Equivalent 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.
