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.
