nm400 weathering steel Material Steel Plate Size

ASTM A283 is only used for structural purposes, and ASME SA283/SA283M steel plates can also be used for boiler and pressure vessel manufacturing. We can provide ASTM A283 steel NM400 weathering steel product forms, including steel plates, steel coils, steel pipes and structural steel products such as section steel, beams, etc. If you need to purchase ASTM A283 steel plates NM400 weathering steel, please contact us.

Compared with ordinary steel, the NM400 weathering steel special steel has the following characteristics. First, the special steel has better physical properties, higher strength, stronger compressive strength, and better precision. Second, the special steel has better chemical properties, such as high temperature resistance, low temperature resistance and corrosion resistance. Third, the composition of the special steel is more diversified, which can be synthesized by integrating other elements, such as alloy steel, high carbon steel, etc. Fourth, special steel is more flexible for processing.

If the chromium content in NM400 weathering steel alloy steel reaches about 12%, dense chromium oxides will be formed on the surface of the steel, which will greatly improve the corrosion resistance of steel in oxidizing media. Chromium, aluminum, silicon and other elements can improve the oxidation resistance of steel and the corrosion resistance of high-temperature gas, but excessive aluminum and silicon will deteriorate the thermoplasticity of steel.

For ASTM A573 Grade 70/A573 Gr.70 carbon manganese silicon steel plates, our company would issue the original mill test certificate NM400 weathering steel EN 10204 3.1 for clients when arrange delivery, so that clients can trace the A573 Gr.70 plates origin easily.

If customers have any difficult problems during use of the steel materials, they can contact the company's after-sales service department to feedback the existing problems. The after-sales department will reply as soon as possible to ensure that each customer has a good after-sales experience. Under special circumstances, the after-sales service department will start the problem-solving process, and the engineers in charge of the area will quickly follow up to solve the problem.
