Introduction to the steel plate grade for 15MnVR pressure vessel

15MnVR is a steel plate for boilers and pressure vessels, which is usually delivered in a normalized condition. It is widely used in petroleum, chemical, power station, boiler and other industries, and is used to make reactors, heat exchangers, separators, spherical tanks, oil and gas tanks, liquefied gas tanks, nuclear reactor pressure shells, boiler steam drums, liquefied oil and gas cylinders, hydropower station high-pressure water pipes, hydro turbine volutes and other equipment and components.

Note:
(1): The data comes from the network and is for reference only.
(2): The formula for calculating carbon equivalent (CE) is as follows: CE=C+Mn/6+(Cu+Ni)/15+(Cr+Mo+V)/5.
The allowable deviation of the size of 15MnVR grade steel plate shall comply with the provisions of GB/T 709-2006. The welding performance of 15MnVR container plate is good, and the factors that usually affect 15MnVR container plate include material factors, process factors, structural factors, etc. One of the factors that affect the welding performance of 15MnVR container plate is metallurgical defects, and the other is the change of material properties during welding.

The default delivery status of 15MnVR grade steel plate is normalizing.
