Product Description

Chromium molybdenum steel, recognized as medium temperature hydrogen resistant steel, is a sophisticated alloy composed of chromium (Cr), molybdenum (Mo), iron (Fe), and carbon (C). This exceptional alloy delivers high-quality performance, making it an ideal material for fabricating valves and pressure vessels that endure high temperatures and pressures. It is also a favored choice in crafting high-end automotive and motorcycle chassis and suspension systems.
The ingenious application of chromium molybdenum steel pipes in the automotive and motorcycle industries is primarily seen in the construction of frames, offering remarkable advantages including lightweight, superior strength, and excellent corrosion resistance.

Furthermore, chromium molybdenum steel pipes find extensive application in oil wells and heat exchange equipment thanks to their outstanding properties of high temperature resistance, high pressure capacity, and superior corrosion resistance.
