Carbon and low alloy 12Cr1MoVR pressure vessel steel sheet with high strength

On November 25, the price of the 12Cr1MoVR pressure vessel steel sheet medium board in the Yinchuan market remained stable temporarily, and the market transactions were average. As of press time, Yinchuan market 16-25mm general medium plate is 4020 yuan/ton; 14-25mm low alloy medium plate is 4170 yuan/ton. The price of plate in Yinchuan market continued to stabilize without much change. However, as the temperature dropped sharply and terminal demand in the local market dropped to a low point, plate merchants in the Yinchuan market had difficulty shipping.

Over the years, the company has trained a number of professional sales talents, enriched the concept of various marketing and customer service, and strengthened the business strength of the company. Now the company's business 12Cr1MoVR pressure vessel steel sheet department, marketing department and information department constitute the market development network; the finance department, personnel department, logistics department, shipping department, document department and 12Cr1MoVR pressure vessel steel sheet after-sales service department constitute the service customer network.

Non-destructive flaw detection of steel plates is a test method for inspecting the 12Cr1MoVR pressure vessel steel sheet surface and internal quality of the inspected parts without damaging the working state of the workpiece or raw materials. Commonly used 12Cr1MoVR pressure vessel steel sheet steel plate flaw detection methods include: X-ray flaw detection, ultrasonic flaw detection, magnetic particle flaw detection, penetration flaw detection, eddy current flaw detection, gamma-ray flaw detection, fluorescent flaw detection, color flaw detection and other methods. Physical flaw detection is non-destructive flaw detection without any chemical changes.

The effect of alloy elements of 12Cr1MoVR pressure vessel steel sheet, Q345B alloy steel plate on tempering transformation: improving the tempering stability. The alloying elements delay the decomposition of martensite and the transformation of residual austenite during the tempering process. Increasing the recrystallization temperature of ferrite makes it difficult for carbides to aggregate and grow, so the resistance of steel to temper softening is improved, that is, the tempering stability of steel is improved.

We should focus on the main problems to be solved and pay attention to efficiency. After receiving the user's quality objection report data, the possible causes, responsible units, compensation amount, etc. of the problem shall be judged based on experience. To have a clear service plan, to be clear about what your main problem is, what technical support is needed, these should be prepared.
