What is 12Cr1MoV Steel?

12Cr1MoV is a low-alloy steel that contains chromium (Cr), molybdenum (Mo), and vanadium (V), elements that enhance its mechanical properties. The main characteristics of 12Cr1MoV steel include:

• High-Temperature Strength: It maintains its strength and stability at elevated temperatures, making it suitable for applications involving high heat.
• Corrosion Resistance: The chromium content provides good resistance to oxidation and corrosion, essential for harsh environments.
• Good Weldability: 12Cr1MoV steel has good weldability, making it easier to fabricate and join into structures and equipment.

Key Features of 12Cr1MoV Steel Plate

• Excellent High-Temperature Strength: The addition of chromium and molybdenum allows 12Cr1MoV steel plates to retain their strength under high-temperature conditions, ideal for power plant components.
• Oxidation and Corrosion Resistance: Chromium improves the steel's ability to resist oxidation and corrosion, even when exposed to hot, reactive environments.
• Good Machinability and Weldability: This steel has good machinability and weldability, enabling easy processing and fabrication in a variety of industrial applications.
• Long Service Life: Due to its strength, resistance to corrosion, and toughness, 12Cr1MoV steel plates have a longer service life, reducing maintenance needs.

Applications of 12Cr1MoV Steel Plate

• Boiler Components: The high-temperature strength and corrosion resistance of 12Cr1MoV steel make it ideal for manufacturing boiler components like headers, steam drums, and superheater tubes.
• Power Plant Equipment: 12Cr1MoV steel is used in high-pressure pipelines and heat exchangers in power plants due to its ability to withstand extreme temperatures and pressure.
• Petrochemical Industry: It is commonly used in pressure vessels and piping systems that need to handle corrosive and high-temperature environments in petrochemical plants.

Benefits of Using 12Cr1MoV Steel Plate

• Superior Performance at High Temperatures: 12Cr1MoV steel plates retain their mechanical properties at high temperatures, ensuring durability and safety in high-heat environments.
• Extended Service Life: The steel's resistance to oxidation and corrosion allows for long-term use with minimal wear, reducing maintenance and downtime.
• Versatile in Multiple Industries: The material is used in power generation, petrochemical, and boiler manufacturing, making it an ideal choice for various high-temperature applications.
• Cost-Effective: While 12Cr1MoV steel may have a higher initial cost than some materials, its durability, resistance to wear, and long lifespan make it a cost-effective solution in the long run.

What is 12Cr1MoV material?

12Cr1MoV steel is normalized and tempered at high temperatures, where its normal metal organization includes ferrite and pearlite (or local bainite). Compared with the same type of low-alloy pearlitic heat-resistant steel, 12Cr1MoV shows better processability and much higher thermal strength.

12Cr1MoVG is a type of high-pressure boiler steel used in the production of boilers and pressure vessels. It has a high temperature strength, good thermal conductivity, and excellent corrosion resistance. It is commonly used in the manufacturing of power plant boilers, industrial boilers, and pressure vessels in the petrochemical industry.

12Cr1MoVG is a Cr-Mo-V low alloy heat-resistant steel introduced from the Soviet Union in the 1950s and 1960s. Vanadium is an element that reduces the y-phase region. When dissolved in y-fe, it will inhibit the transformation of ADI to pearlite, which is beneficial to the formation of ADI. The total amount of alloy in 12Cr1MoVG steel is only one half of that of 2.25Cr-1Mo steel, but the endurance strength (580 ° C) is 1.4 times of that of 2.25Cr-1Mo steel. Similar steel grades widely used abroad include ASTM a405 p24 in the United States, bs3604 in the United Kingdom, DIN 13crmov42 in Germany, etc.

12Cr1MoVG material equivalent

The material 12Cr1MoVG is commonly used in the production of high-pressure boiler tubes and piping systems. Its equivalent materials in other standards include:

• ASTM A387 Grade 11 Class 2
• ASME SA387 Grade 11 Class 2
• EN 10216-2 13CrMo4-5
• JIS G4109 SCM415
• GB/T 3077 12Cr1MoV

What is 12Cr1MoVG equivalent to ASME?

The equivalent material to 12Cr1MoVG in the ASME standard is ASTM A335 P11. Both materials have similar chemical compositions and mechanical properties, making them suitable for use in high-temperature and high-pressure applications, such as in the construction of boilers and piping systems.
