Product Detail

Chromium molybdenum steel is an alloy of chromium (Cr), molybdenum (Mo), iron (Fe), and carbon (C).

Chromium-molybdenum steel, also known as medium-temperature anti-hydrogen steel, refers to steel grades such as Cr (<10%), Mo and other alloying elements to significantly improve the high temperature strength limit and creep limit, and has good resistance to hydrogen corrosion and high temperature.

Performance, so it is widely used in hydrogen-containing equipment and high-temperature equipment such as refining and chemical industry. It is one of the commonly used steel grades for pressure vessels.
