GB/T1591 Q345B low alloy structural steelSteel grade Q345B is the most common used as high strength low alloy structural steel in industry area.BBN steel can offer steel coils,steel plates,angles,channels for Q345B materials.The equivalent steel grade with Q345B are EN 10025-2 S355JR,ASTM A572/A572 A572 Grade 50 and DIN 17100 St52-3. Full Data Technical Requirements & Additional Services:
It is a steel with less than 0.2 percent of its composition made up of carbon, less than 0.55 percent of its composition made of silicon and several impurities (mostly sulfur, chromium and nickel). 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 Q345 Steel Equivalent, Specification, Chemical Composition 2020-11-23 17:27. 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.
To some extent, the Q345 possesses the same property and composition of ASME A572, namely the Q345 is equivalent to A572. This specification covers the standard requirements for Grades 42, 50, 55, 60, and 65 of high-strength low-alloy structural steel shapes, plates and sheet for applications in bolted, welded, and riveted structures in bridges Q345B (GB ) - Worldwide equivalent grades - Steel NumberChemical composition and properties of european equivalents (EN) for Q345B (China, GB ):S355JR (1.0045) , Q345B (China, GB ) - European (EU, EN) and wordwide Steel equivalent grades.
