High toughness and low brittleness transition temperature: with the increase of the working pressure of the A709 Gr HPS100W bridge steel plate gas pipeline, the pipe diameter becomes larger, and the pipeline fracture accidents often occur. Toughness is the key factor affecting pipeline fracture. In order to ensure A709 Gr HPS100W bridge steel plate pipeline safety, toughness and strength must be improved at the same time.
Q345R material is a special steel grade for pressure vessels with a yield strength of 340MPa. It has good comprehensive mechanical properties and technological performance. The phosphorus and sulfur contents are slightly lower than the low-alloy high-strength steel plate Q345 (16Mn) steel. In addition to the increased tensile strength and elongation requirements compared to Q345 (16Mn) steel, it also requires impact toughness. Q345R steel plate is currently the most widely used and most used steel plate for pressure vessels in China.
