12Cr1MoV alloy steel pipe




The main characteristics of 12Cr1MoV alloy steel pipe: The creep limit of this steel is close to the endurance strength value, and it has high plasticity under the condition of permanent stretching; the processability and weldability of steel are good, but it needs to be preheated to 300 ℃ After the welding, stress removal is required.
It is a widely used steel type for high-pressure, ultra-high pressure, subcritical power plant boiler superheaters, headers and main steam ducts. At 580 ℃, it still has high heat resistance and oxidation resistance, and has high lasting plasticity. The production process is relatively simple and the welding performance is good, but it is more sensitive to the normalizing cooling rate. Long-term use at 580 ° C will produce pearlite spheroidization. The biggest advantage is that it can be recycled 100%, which is in line with the national strategy of environmental protection, energy saving and resource conservation. The policy encourages the expansion of the application field of 12Cr1MoV alloy steel pipes.

At present, the consumption of 12Cr1MoV alloy steel pipe in China accounts for only half of the total steel. The expansion of the field of 12Cr1MoV alloy steel pipe provides a wider space for the development of the industry. According to the research of the 12Cr1MoV alloy steel pipe branch of the China Special Steel Association, the demand for high-pressure 12Cr1MoV alloy steel pipe long products in China will grow by an average annual rate of 10-12% in the future.

Title: Alloy Steel Pipe 2
Brief introduction: Fine seamless steel pipe classification Fine seamless steel pipe is divided into ordinary and hydraulic, in general, hydraulic is more durable than ordinary, but also more convenient to use, we will look at these two types of fine Related types and clarification of seamless steel pipes: Ordinary fine seamless steel pipes are commonly used in machinery or systems that have no special requirements for the precision and pressure resistance of fine seamless steel pipes. Hydraulic fine seamless steel pipes generally require high precision and high pressure resistance. Seamless fine seamless steel pipe. At present, the fine seamless steel pipes used in hydraulic systems are mainly stainless steel seamless pipes, ordinary seamless fine seamless steel pipes, DIN2391 high-precision hydraulic fine seamless steel pipes. Although stainless steel seamless pipes have superior mechanical properties, they are expensive The accuracy is low and it has not been widely used. The ordinary seamless fine seamless steel pipe is widely used, but its mechanical properties are poor, and the accuracy is ... [ detailed ]
