SX105V
| Supported standards | Aichi Brand Steel flame-hardening steel |
|---|---|
| Type of steel | SX105V |
Features
SX105V is a flame hardening steel used widely in metal stamping dies for car body parts.
SX105V offers a wide range of proper heating temperature and optimal hardenability. After burner heating and following quenching in air. SX105V becomes easy to obtain consistent high hardness unlike in case of SKD11or SKS3.
