We solve difficult problems with integrated support from carbide materials to finished product manufacturing!
Material List
KN40
JIS standard: NF-50
Features
Carbide grade with excellent nonmagnetic, corrosion and heat resistance properties as a result of replacing binder phase with Ni.
This grade's impact resistance and fracture toughness is higher than KN30 due to higher Ni content, however wear resistance is reduced by one rank.
Equipments using KN40
| Press working machine | Powder forming machine |
| Resin molding machine | Cutter machine |
Applications of KN40
| Punch, Die | Gate, Runner, Core pin |
| Guide, Conveyor Rails, Positioning Jig | Seal (stake) |
| Roll forming rollers | Rolling mill roll |
Parts manufactured with KN40
