The deoxidization process of Q345R boiler vessel plate if the type and amount of deoxidizer are controlled to make a certain amount of oxygen remain in the sa709 grade 36 structural carbon steel steel, when sufficient amount of strong oxidant is added to make the steel deoxidize well, the co bubble will escape during the solidification process and generate boiling phenomenon, no co bubble will be generated during the solidification of the sa709 grade 36 structural carbon steel steel, the steel used for the pressure vessel of the killed steel is called the killed steel, this kind of steel is called the boiling steel.
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.
