Introduction of 14cr1mor pressure vessel steel plate].
1. Introduction to 14Cr1MOR pressure vessel steel plate.
14Cr1mor is a high-strength, high-toughness, corrosion-resistant steel plate for pressure vessels, which is widely used in petroleum, chemical industry, electric power, nuclear energy and other fields. The "14Cr" in the grade indicates that the steel plate contains 14% chromium, "Mo" indicates that it contains molybdenum, and "R" represents steel for pressure vessels.
Second, the characteristics of 14cr1mor pressure vessel steel plate.
1.High strength: 14Cr1mor steel plate has high tensile strength and yield strength, which can meet the design requirements of various high-pressure vessels.
2.High toughness: The steel plate can still maintain good toughness in low temperature environment, and is suitable for making low-temperature pressure vessels.
3.Corrosion resistance: 14Cr1Mor steel plate contains chromium and molybdenum elements, which has good corrosion resistance and can resist the erosion of a variety of chemical media.
4.Good welding performance: the steel plate is not easy to produce cracks and porosity during welding, and the welded joint has high strength, which can meet the welding requirements of pressure vessels.
5.Good processing performance: After proper heat treatment, 14cr1mor steel plate has good machinability and can be used for cutting, bending, rolling and other processing operations.
3. The manufacturing process of 14Cr1Mor pressure vessel steel plate.
1.Steelmaking process: electric furnace or converter is used to make steel, and an appropriate amount of chromium, molybdenum and other alloying elements are added to control the purity of molten steel.
2.Rolling process: The refined steel ingots are heated and rolled, and the steel plate is controlled by multi-pass rolling and cooling to obtain the required structure and properties.
3.Heat treatment process: Proper heat treatment, such as quenching and tempering, is applied to the rolled steel plate to obtain the desired mechanical properties and processing properties.
Fourth, the application of 14Cr1Mor pressure vessel steel plate.
Due to its excellent performance and wide applicability, 14Cr1Mor pressure vessel steel plate is widely used in petrochemical, nuclear, pharmaceutical and other fields. For example, in the petrochemical industry, the steel plate can be used to manufacture high-pressure vessels such as oil tanks, liquefied gas tanks, reactors, etc.; In the field of nuclear energy, it can be used to manufacture key equipment such as pressure vessels for nuclear reactors; In the pharmaceutical field, it can be used to manufacture high-temperature, high-pressure pharmaceutical equipment.
V. Conclusions. As a high-performance steel plate for pressure vessels, 14cr1mor has a wide range of applications in many fields. Its excellent mechanical properties, corrosion resistance and good processing and welding properties make it ensure the safe and reliable operation of the pressure vessel, and also greatly improve the service life of the vessel. In the future, with the continuous development of science and technology, it is believed that 14Cr1Mor pressure vessel steel plate will be applied and promoted in more fields.
