Mechanical properties and application of p265gh steel tube

Pageviews:

X-rays or γ-rays are projected on the surface of the steel plate, and rubber can be placed on the other side of the steel plate. Since the radiation propagates through the steel plate and is absorbed, the intensity is different due to the presence or absence of defects, so the film can record the shape and position of the defects. This P265GH steel tube method is sensitive to the detection of common steel plate defects such as slag inclusions, porosity and pores. The disadvantage is that it is difficult to find the specific depth of the defect and it is not easy to find cracks.

The production process of p265gh steel tube, SA737 Gr B and SA737 Gr C steel plates: open hearth, oxygen blowing converter or electric furnace. The SA737 Gr B and SA737 Gr C steel should be killed steel and meet the requirements of fine austenite grain size in the A20/A20M standard. The material is heated to an appropriate temperature for normalizing to form an austenite structure, but the temperature should not exceed 925.

We have gradually formed four advantageous products of steel plate, steel pipe, p265gh steel tube, stainless steel and special steel, and established our own processing center to meet the diversified needs of customers. At the same time, we also set up professional environmental protection, baby carriage and other projects. With the professional team and strong background of steel plate, steel pipe, stainless steel and special steel, it will drive the rapid development of other projects.
