ICS22
Material for molding which hardly cracks by hobbing and is superior in hardenability and toughness.
Cold tool steel which has an aptitude for carburizing and quenching.
Difficult to crack when material of hardness less than 171HB is processed by hobbing.
Good hardenability and vacuum quenching aptitude have been obtained.
Applications
| By mass production or small-quantity production and low load |
For Eyeglass frames, Clocks, Coins and so on. quench and temper after cold hobbing. |
| By mass production and high load |
For Screws, Bolts and Auto parts. carburize after cold hobbing. |
