In the previous article, we talked about the tools are mainly made from steel, the hardness and flexibility will affect the operation, so the key point is the carbon content. “Low carbon steel” <0.25% “Medium carbon steel“ 0.6%< “High carbon steel”
Low carbon steel is often used on less strength mechanic parts.
The most common materials used for tools are high carbon steel and CRV.
CRV is an alloy contains element CR and V, it is ideal material to use on sockets, screwdrivers and wrenches. CR-Mo is an alloy contains element CR, Mo, Fe and C.
Mostly used on impact sockets for better torque force. S2 is better material to use on hex key. SVCM is excellent alloy to manufacture screwdrivers for durable and strength.
The above knowledge sharing is from HTI internal training, Tom, our VP, has involved in hand tools industries for over 20 years. His abundant experience inherits and educates hand tools knowledge to our whole team. To soak up information, everyone gets to know our industry better and helps to serve our customers with profession.
