05CuPCrNi steel normalized and impact tested plate

Q370R Pressure Vessel Steel: Steel used to manufacture pressure vessels in petrochemical, gas separation, gas storage and transportation equipment. It is required to have sufficient strength and toughness, good welding performance and hot and cold processing performance. The commonly used steels 05CUPCRNI steel are mainly low-alloy high-strength steel and carbon steel. Q370R implements the domestic standard GB713-2008.

The 05CUPCRNI steel, wear-resistant plate after VD treatment is generally high-quality wear-resistant plate with high added value. In addition to the strict requirements for the composition of wear-resistant plate, the requirements for the anti-fatigue pull-out damage performance of the wear-resistant plate are also very strict. Therefore, the non-metallic inclusions, especially the large non-metallic inclusions and brittle inclusions, must be strictly controlled.

The 05CUPCRNI steel steel making furnace can only be used as primary refining, and the refining needs to be completed in the refining equipment outside the furnace, which is also called secondary refining. It is mainly through decarburization, desulfuration, denitrification and dephosphorization to improve the cleanness of the steel, to establish a chromium molybdenum low alloy steel with good oxidation resistance and high temperature strength, to remove unwanted harmful impurities from the steel, and to improve the 05CUPCRNI steel internal quality of the steel.
