Tips: Materials of sockets

1. Chrome-molybdenum steel
Chrome-molybdenum steel (CR-Mo) is made of chromium (Cr), molybdenum (Mo), iron (Fe), and carbon (C). High temperature processing performance is good. Chromium molybdenum steel has the characteristics of fine appearance after processing, deep quenching, and good impact absorption performance, so it is often used to manufacture pneumatic tools and large hand tools in the industry, such as impact sockets, air impact wrench, etc.

2. Chrome vanadium steel
Chrome vanadium steel (CR-V) is an alloy tool steel with chromium vanadium alloy elements, mainly used in hand tools like screwdrivers, wrenches, pliers, ratchet and sockets, etc.

3. 45# carbon steel
The 45# steel has a carbon content of about 0.45%. Because of its good workability and multi-directional processing technology, it has become a commonly used processing material in steel.

Among the materials mentioned above, the chromium-molybdenum steel socket has the best performance, and has excellent performance in terms of service life and torsion resistance.
