Specifically for container board Q345R North Run Metal Materials Co., Ltd. Shanghai Tel :021 -56,699,572 Mobile: 15601805059 Contact: Huang Yang container steel plate Q345R is in a category - container board grades that way: Q345R 16MnR 16MnG. For example: Q345R. Q-"framed" Pinyin first letter. 345 - yield strength values. R: "content" Pinyin first letter. According to September 1, 2008 implementation of the "GB 713-2008 boiler and pressure vessel steel plate," the new classification, 16Mng and 16MnR, 19Mng merged into Q345R. Q345R is an ordinary low-alloy steel, boiler and pressure vessel steel used is the delivery status of: hot rolled or normalized, is a low-alloy steel. Performance and Q345 (16Mn) in (16mm steel yield strength greater than 345Mpa) similar performance, tensile strength (510-640) between the elongation greater than 21%, the impact energy is greater than zero V-34J. Q345R process reference standard GB713-2008. Q345R steel is the yield strength of 340MPa grade pressure vessel dedicated board, it has good mechanical properties and process performance. Phosphorus, sulfur content lower than low alloy high strength steel Q345 (16Mn) steel, in addition to tensile strength, elongation requirements than Q345 (16Mn) steel has increased, but also requires guaranteed impact toughness. It is currently the most widely used of the largest amount of special steel pressure vessel. Features Q345R Q345R yield strength of steel is 265-345MPa grade pressure vessel dedicated board, it has good mechanical properties and process performance. Phosphorus, sulfur content lower than low alloy high strength steel Q345 (16Mn) steel, in addition to tensile strength, elongation requirements than Q345 (16Mn) steel has increased, but also requires guaranteed impact toughness.
