Q345R Steel Plates Of Pressure Vessel
Q345R steel Product Introduction
Q345R steel is a low alloy steel for pressure vessels with yield strength of 345MPa grade, which has good comprehensive mechanical properties and process performance. Phosphorus and sulfur content is slightly lower than low alloy high strength steel plate Q345 (16Mn) steel, in addition to tensile strength, elongation requirements than Q345 (16Mn) steel has increased, but also to ensure impact toughness.
Q is the first letter of Chinese Pinyin, 345 represents yield strength, r is the first letter of Chinese Pinyin, and its brand naming method is low alloy high-strength structural steel brand, represented by the first letter of Chinese Pinyin for yield strength value and pressure vessel capacity.
