Chromium-molybdenum steel, also known as medium-temperature hydrogen-resistant steel, is an alloy of chromium (Cr), molybdenum (Mo), iron (Fe) and carbon (C). It has good quenching performance and can be quenched in depth to replace the surface quenching of anti-saw locks in the market. Because of its special high-quality performance, it is often used to manufacture some high-temperature and high-pressure resistant valves and pressure vessels, such as chrome-molybdenum steel safety valves, chrome-molybdenum steel gate valves, screwdriver bits, bicycles and so on.

1、42CrMo
42CrMo steel belongs to plastic die steel in material classification, which has good mechanical properties and machinability and is widely used. There are mainly two kinds of materials: plate and round bar, in which plate is used for mold processing and round bar is used for machining parts directly by machinery, which has been recognized by the industry.
2、35crmo
35CrMo is the specification number of alloy structural steel (alloy quenched and tempered steel), which is mainly used to manufacture important parts in various machines subjected to impact, bending and torsion and high load.
3、 15CrMo
15CrMo steel is a pearlite heat-resistant steel with high thermal strength (Δ b ≥ 440 MPa), oxidation resistance and hydrogen corrosion resistance at high temperature. Because of the high content of alloying elements such as Cr and C in steel, the hardening tendency of steel is obvious and the weldability is poor.
