Q345B steel is a Chinese standardized low alloy, medium tensile strength steel made with a hot-rolling process, and is used for a number of manufacturing purposes. 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 National Standards of the Peoples Republic of ChinaSpecification for flat products made of steel for pressure purposes, combining and revising GB 713-1997 Steel plates for boilers and GB 6654-1996 Steel plates for pressure vessels. GB 713-1997 Steel plates for boilers and GB 6654-1996 Steel plates for pressure vessels will be superseded by this standard as from its issue date. 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 q345b steel specification pdf steel pipeT 1591-2018 release is Q345B , because the output of PRODUCTS HANDBOOK Structural Steeland Z Purlins, Mild Steel Plates, Chequered Plates, API 5L (1991) and ASTM A53 (1997) pipes, Steel Sheet Piles to EN 10248:1996 and Other Steel Sheet Piles.
