Q345R/SA 515 GR 60 Pressure Vessel Steel Plate
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 requiresguaranteed impact toughness. It is currently the most widely used of the largest amount of special steel pressure vessel.
According to the new classification of "GB 713-2008 Steel Plates for Boilers and Pressure Vessels" implemented on September 1, 2008, 16Mng, 16MnR, and 19Mng were merged into Q345R. Q345R is ordinary low-alloy steel, which is commonly used for boiler and pressure vessels.
Q345R steel is a special plate for pressure vessels with a yield strength of 340MPa. It has good comprehensive mechanical properties and process performance. Phosphorus and sulfur content is slightly lower than that of low-alloy high-strength steel Q345 (16Mn) steel. In addition to higher tensile strength and elongation requirements than Q345 (16Mn) steel, it is also required to ensure impact toughness. It is currently the most widely used and most used special steel plate for pressure vessels in my country.
