Supply and demand analysis of p265gh material market

Pageviews:

Compared with the traditional seamless steel pipe, alloy seamless pipe has better performance in all aspects. Because of the addition of various metal elements in the manufacturing, the overall strength of the alloy seamless pipe is larger, stronger and durable, and the service performance and service life of the P265GH material, alloy seamless pipe are improved. The alloy seamless pipe is the best choice especially for special environment and high pressure requirements. Because of its high material properties, alloy seamless pipe has good corrosion resistance. It is not easy to be corroded in some special environment, which reduces the cost of the project and has a longer service life.

Vanadium element (V element) can refine grains in ordinary low carbon alloy steel, improve the strength and yield ratio and low temperature characteristics after normalizing, and improve the welding performance of steel, p265gh material included. Vanadium element (V element) is often used in combination with manganese, chromium, molybdenum, tungsten and other elements in structural steel because of its low hardenability under general heat treatment conditions. Vanadium in quenched and tempered steel is mainly to improve the strength and yield ratio of steel, refine the grain size, and pick up the overheating sensitivity.

p265gh material, SA387Gr22CL2 low alloy high strength steel with high purity and good quality is used for high temperature boilers or other high temperature pressure vessels. Chemical composition of SA387Gr22CL2 steel: C: 0.05 - 0.15; Mn ≤ 0.10; Si: 0.30 - 0.60; P ≤ 0.010; S ≤ 0.005; Cr: 2.00 - 2.50; V ≤ 0.010; Mo: 0.90 - 1.10; Nb ≤ 0.010; Al ≤ 0.06; Ni ≤ 0.20; Cu ≤ 0.15; Ti ≤ 0.010.

Before laying, if there is bending deformation, it should be corrected in time.
