Classification by material

1. Chrome-Molybdenum Steel is an alloy of chromium (Cr), molybdenum (Mo) and iron (Fe), carbon (C). It has good high-temperature processing performance, beautiful after processing, and can be deeply quenched. Good absorption performance, so it is often used in the industry to make pneumatic tools and large hand tools.

2, Chrome-Vanadium Steel (Chrome-Vanadium Steel), chromium-vanadium steel is an alloy tool steel with chromium-vanadium alloy elements, mainly used in manual tools.

3. 45 # carbon steel, namely 45 # steel, has a carbon content of about 0.45%. It has become a common processing material in steel due to its good processing performance and multi-faceted processing technology. Among the above materials, the best Cr-Mo (chrome molybdenum steel) material is the best material for the sleeve.
