ASTM A213 T9 seamless pipe is ferritic and austenitic alloy-steel boiler, superheater, and heat-exchanger tubes. BBN steel company supplies Cr-Mo low alloy steel grades of T2, T5, T5b, T5c, T9, T11, T12, T17, T21, T22, T23, T24, T36, T91, T92, T122, and T911. The tubing sizes and thickness usually furnished to this specification are 1/8″(3.2 mm) in inside diameter to 5″(127 mm) in outside diameter and 0.015″ to 0.500″(0.4-12.7 mm) in minimum or average wall thickness.

The wear-resistant layer of S275ML steel plates wear-resistant steel plate is mainly composed of chromium alloy, and other alloy components such as manganese, molybdenum, niobium and nickel are added. The carbide in the microstructure is distributed in the form of fiber, and the direction of the fiber is perpendicular to the surface. The microhardness of carbides can reach hv1700-2000 and HRC58-62 respectively. The alloy S275ML steel plates carbide has strong stability at high temperature, high hardness and good oxidation resistance. It can be used normally within 500 ℃.

During the steel plate cutting, the special-shaped steel plate cutting process is often carried out. In this operation process, some cutting curves will be generated. Therefore, there should be relatively high precision standards during the processing of S275ML steel plates. The operators need to have rich experience, and they also need to be proficient in the operation methods and working skills of the equipment, so as to ensure that the steel plate can meet the shape requirements after processing.

The company specializes in hot rolled plates producing, steel plate processing, steel plates cutting, carbon steel plate weldding and exporting of wide and thick steel plates. BBN company has high-quality CNC S275ML steel plates steel plate cutting processing equipment, professional technical personnel, and supporting marketing and after-sales service system. Sincerely welcome new and old customers to visit our company, BBBN company will always be your reliable choice.
