Some regard Q345B, A572 Gr.50, S355JR, ST52-3 etc. high strength low alloy steel as ASTM A131 AH36 steel equivalent. Is that reliable? Let us make a comparion in those steel materials. ASTM A131 AH36 steel and so called ASTM A131 AH36 steel equivalent chemical composition: ASTM A572 Gr 50 vs Q345BMay 07, 2013 · By Euskera Date 04-30-2013 21:49. 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 speciall filler welding rods for that material,
Dec 12, 2019 · World Iron & Steel Co. Updated:Dec 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 JIS G3101 SS400 equivalent steel materials steel plate,JIS There are various JIS G3101 SS400 equivalent steel materials on the market. The ASTM equivalents for JIS G3101 SS400 steel are ASTM A36 and ASTM A283C; the EN equivalent for JIS G3101 SS400 steel is S235JR.The DIN equivalent for JIS G3101 SS400 steel is ST37-2; and the GB equivalent for JIS G3101 SS400 steel is Q235B. 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

Q345 steel:Q345A, Q345B, Q345C, Q345D, Q345E equivalent to US ASTM, European Germany DIN, British BS, France NF, Japan JIS, and ISO Standard (For Reference). Notes:Q345 steel has been replaced by Q355 in the latest version of GB standard GB/T 1591 2018, the previous version is GB/T 1591 2008. Q345 steel property and specification are equivalent to Q345 steel is one kind of Chinese standardized low alloy, medium tensile strength steel made with a hot-rolling process, used for a number of manufacturing purposes. To some extent, the Q345 possesses the same property and composition of ASME A572, namely the Q345 is equivalent to A572.
