Tien-I Chooses Taiwanese Chrome Vanadium Steel for Durability and Resilience

To make good tools, you need good quality steel. That's why Tien-I chooses to manufacture with chrome vanadium steel (Cr-V) from Taiwan.

 

Chrome vanadium steel is iron alloyed with chrome and vanadium. It shows high resistance to corrosion and possesses suitable rigidity. For example, for sword-making, chrome vanadium steel is far superior to simple carbon steel in overall strength when spring tempered (50 HRC).

 


Edge-holding advantage

 Different steels have different edge-holding capabilities. Chrome, a very hard metal, adds hardness to steel. Vanadium, a brittle metal, adds toughness. The end result is a steel that holds an edge and doesn't dull with repeated use.



Carbon steel = quality compromise?

Carbon steel is a very common type of steel. The percentage of carbon determines whether the steel is high-, middle- or low-carbon steel. As its carbon content rises, the hardness of steel increases.

Lower carbon steel is suitable for forging or die casting. Most DIY hand tools are manufactured using this kind of carbon steel, as it is cheap and easy to access. However, such tools are not highly durable, and they are not suitable for precise processing. That's why we don’t use this type of material for our clients.

Tien-I's tools are made from chrome vanadium steel for higher durability and resistance to corrosion. That's why our hand-tool sockets always bear the CR-V mark.

Ｑ＆Ａ

What kind of factory is Tien-i?

Tien-I is a manufacoturer at professional designing tool kit and producing OEM/ODM products. 

Is the bit head magnetic?

Please provide the sample or the photo for us reference to see which bits you ask for.

What is the popular size of impact sockets?

What kind of tool kit do you want? And what’s the sales territory? Different countries have different popular sizes. Welcome to send us an email for further discussion. .

What is the popular size of chrome sockets?

What kind of tool kit do you want? And what’s the sales territory? Different countries have different popular sizes. Welcome to send us an email for further discussion.

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.
