Product Description

 

   Chromium molybdenum steel, also known as medium temperature hydrogen resistant steel, is an alloy of chromium (Cr), molybdenum (Mo), iron (Fe), and carbon (C). Due to its special high-quality performance, it is often used to manufacture valves and pressure vessels that are resistant to high temperatures and pressures, and is also commonly used in high-end automotive and motorcycle chassis and suspension systems.
   The application of chromium molybdenum steel pipes in automobiles and motorcycles is mainly reflected in the manufacturing of frames, with advantages such as lightweight, high strength, and corrosion resistance

    Meanwhile, chromium molybdenum steel pipes are widely used in oil wells and heat exchange equipment due to their excellent properties such as high temperature resistance, high pressure resistance, and corrosion resistance.
