Q345R Features

。 Q345R steel yield strength of 265-345MPa grade pressure vessel dedicated board, it has good mechanical properties and process performance.Phosphorus, sulfur content is slightly lower than high-strength low-alloy steel plate Q345 (16Mn) steel, in addition to the tensile strength, elongation requirements than Q345 (16Mn) steel has increased, but also sought assurances that toughness.It is currently China's most widely used, the largest amount of special steel pressure vessel.
