12Cr1MOVR and 12Cr1MOV are two different steels, and although they have similar names, there are some differences in terms of chemical composition, application areas, and performance characteristics. Wugang Xinze Steel
1.Chemical Composition:Li TangThe chemical composition of 12Cr1MOVR is usually 008% to 0Between 15%, the chromium (CR) content is 09% to 12%, the content of molybdenum (Mo) is 025% to 035%, vanadium (v) content is 015% to 030%。The chemical composition of 12Cr1MoV is 008% to 0Between 15%, the chromium (CR) content is 090% to 120%, the content of molybdenum (Mo) is 025% to 035%, vanadium (v) content is 015% to 030%。It can be seen that there is a certain similarity in the chemical composition of the two.
2.Applications:12Cr1MOVR steel is mainly used in high and medium pressure boilers and pressure vessels, and is widely used in chemical, petroleum, natural gas industry and other fields. And 12Cr1MOV steel is also a low-alloy high-strength steel, which is often used in the manufacture of high-temperature and high-pressure equipment, such as boilers, pipelines, oil platforms, etc. Both have a wide range of applications in high-temperature and high-pressure environments, but there are slight differences in application fields.
3.Performance characteristics: 12Cr1MOVR steel has good stability and oxidation resistance at high temperatures, and can withstand complex stress environments under high temperature and high pressure. At the same time, it also has good corrosion resistance, which is suitable for industrial occasions with high requirements for corrosion resistance. The 12Cr1MOV steel has good high-temperature strength, high ductility and toughness, and can maintain good mechanical properties at high temperatures. In addition, 12Cr1MOV has excellent processing performance and weldability, making it easy to process and weld.
In summary, 12Cr1MOVR and 12Cr1MOV have slight differences in terms of chemical composition, application fields and performance characteristics. When choosing to use, it is necessary to comprehensively consider various factors according to the specific engineering and equipment requirements, and make a reasonable choice. For high-temperature and high-pressure industrial equipment, both steels have good performance, but the specific use needs to be comprehensively evaluated according to actual needs and standard specifications.
