Chromium molybdenum steel, revered as medium temperature hydrogen resistant steel, is a superbly engineered alloy consisting of chromium (Cr), molybdenum (Mo), iron (Fe), and carbon (C). Renowned for its exceptional high-quality performance, it is extensively utilized in the crafting of valves and pressure vessels capable of withstanding extreme temperatures and pressures. It also finds its esteemed place in the realm of high-end automotive and motorcycle chassis and suspension systems.
The integration of chromium molybdenum steel pipes within the automotive and motorcycle industries is predominantly evident in frame manufacturing. These pipes offer significant benefits such as remarkable lightness, exceptional strength, and outstanding corrosion resistance.
