ASTM A572 Gr 50 vs Q345B

May 07, 2013 · Hello everybody:The Technical Specifications for metal works (gates, trash racks, etc.) of a hydro project indicate, particularly, for the gates to use steel ASTM A572 Gr 50 or its equivalent S355JR according to EN 10025. The Contractor is trying to change that material to steel Q345B (chinese material and code). At the same time, this Contractor says that they, in China, have developed ASTM A572 Grade 50 - A572 Grade 42, 50, 60, 65 Steel Material Properties The following material properties are ASTM specifications and will be confirmed on the Mill Test Report. Grade Yield Point (ksi) Tensile Strength (ksi) Min. 8" Elongation % 42 42 60 20 50 50 65 18 55 55 70 17 60 60 75 16 65 65 80 15 Chemical Composition The following composition properties are ASTM specifications for the A572 grades. Grade 42 + Grade 42 Carbon max 0.21%
