Supply SA514 grade B steel material Boiler Plate

There are several grades of ferritic steel covered by A333 seamless and welded carbon and alloy steel pipe standard: Grade, Grade 3, Grade 4, Grade 6, Grade 7, Grade 8, Grade 9, Grade 10 and Grade 11. BBNsteel company provides ASTM A333 pipes made by the seamless or welded process with the addition of no filler metal in the welding operation except that Grade 4 shall be made only by seamless process. The pipe SA514 grade B steel material shall be furnished free of welding repair, either radiographically tested or ultrasonically examined.

The difference between cold rolled steel sheet and hot rolled steel plate. The carbon content of SA514 grade B steel material, hot rolled steel plate is slightly higher than that of cold rolled steel sheet. In the case of little difference in composition, the density of cold rolled steel sheet and hot rolled steel plate is the same. Hot rolled steel plate has characteristics of low hardness, easy processing and good ductility. Cold rolled steel sheet has high hardness, and it is relatively difficult for processing. But it is not easy to deform and has high strength. Hot rolled steel plate can be made into alloy steel plate by adding other elements, and its properties are also excellent compared with other high-quality steel plates.

The allowable working temperature of boiler steel plate is generally below 475 ℃, which can't meet the needs of high temperature working condition. Chromium molybdenum steel is one of the common steels for SA514 grade B steel material pressure vessels, which is widely used in various hydrogenation units and reforming units in oil refining and chemical industry. Therefore, on the basis of common SA514 grade B steel material carbon steel, alloy elements such as Cr Mo V are added, which has excellent hydrogen corrosion resistance and good high temperature strength, It is the material of high temperature and high pressure vessel shell and head.
