Why Tien-I won't use "only" Carbon Steel

Carbon Steel is very common type of steel. The percentage of carbon will decide whether the steel is high, middle or low carbon steel.  With more carbon, the hardness of steel will go higher. Usually lower carbon steel is suitable for forging or die casting.

 

Most of DIY hand tools will go for this kind of carbon steel. It is cheap and easy to access. However, the durability of tool will not be longer and it is not suitable for precise processing. That's why Tien-I won't use this type of material for our clients.

What is the difference between impact socket and chrome socket? Why is CR-V material not suitable at producing impact sockets?

Tien-i's hand sockets are made of Cr-V steel (CR-V).

Compared with the raw material "CR-V" for hand sockets, the raw material for pneumatic sockets, CR-MO, has stronger toughness, i.e. stronger shock resistance. Suitable for use with air and electric guns. CR-V steel (CR-V) has higher hardness, but in the need for shock-resistant use environment will lead to reduced service life.
