GB 12Cr1MoVR Steel Plate

Overview of GB 12Cr1MoVR Steel Plate

GB 12Cr1MoVR is a high-performance chromium-molybdenum-vanadium alloy steel plate specified under the GB 713 standard, specifically engineered for high-pressure and high-temperature service in boilers and pressure vessels. The “12” denotes its nominal carbon content of 0.12%, while “Cr”, “Mo”, and “V” represent the critical alloying elements of Chromium, Molybdenum, and Vanadium. The “R” signifies its certification for Pressure Vessels (Rongqi). This grade is designed to provide exceptional creep strength and structural stability in thermal environments exceeding 500°C.

Shandong Tanglu Metal Material Co., Ltd. supplies premium GB 12Cr1MoVR plates that undergo sophisticated Normalizing and Tempering (N+T) heat treatment to ensure a refined, stable microstructure. The addition of Vanadium (V) significantly enhances the material’s strength and grain refinement, making it superior to standard Cr-Mo steels in preventing thermal deformation. For B2B buyers in the global power generation and petrochemical sectors, our 12Cr1MoVR plates offer a high-yield, heat-resistant solution backed by rigorous quality control and original Mill Test Certificates (MTC).

Key Features and High-Temperature Advantages

The primary advantage of GB 12Cr1MoVR is its outstanding high-temperature creep resistance and oxidation stability. The synergy between Chromium and Molybdenum provides excellent corrosion resistance and sustained strength at elevated temperatures, while the Vanadium content ensures superior hardenability and resistance to softening during prolonged thermal exposure. This allows for the design of high-pressure components that maintain their integrity under the most demanding operating conditions in modern power plants and refineries.

From a fabrication perspective, GB 12Cr1MoVR requires professional handling, including specific preheating and post-weld heat treatment (PWHT) to ensure the safety and longevity of welded joints. The material exhibits high internal purity and excellent workability, performing reliably during CNC plasma cutting and vessel shell rolling. At Tanglu, we prioritize material traceability and provide full documentation to support the safety-critical requirements of large-scale industrial engineering projects, ensuring compliance with international high-pressure standards.

Main Applications of GB 12Cr1MoVR Steel

GB 12Cr1MoVR is a foundational material for high-temperature and high-pressure industrial systems. It is extensively used in the fabrication of high-pressure boiler drums, superheater headers, and main steam piping in power plants. In the petrochemical industry, it is the preferred material for high-temperature separators, hydrogenation reactors, and heat exchangers that operate under significant thermal stress.

Beyond power and petrochemical facilities, 12Cr1MoVR is essential for the construction of gas storage tanks and large-scale pressure components in the chemical processing sector. Its proven reliability in extreme thermal environments also makes it a critical choice for carbon capture systems and advanced energy recovery units. Due to its advanced alloying and specialized heat-resistant properties, GB 12Cr1MoVR is the global benchmark for high-performance Cr-Mo-V alloy pressure vessel steel.
