White iron is selected for its hardness and ability to withstand harsh, abrasive conditions. It’s the material of choice where extended wear life is critical and impact loads are minimal.
Very high surface hardness (up to 700+ BHN)
Excellent resistance to sliding and gouging wear
High-chromium options for added corrosion protection
Ideal for high-friction, low-impact applications
We cast white iron components that protect equipment, extend service life, and perform in the harshest conditions.
Applications include:
| Grade | Designation | Hardness (As Cast), min (HBW) |
|---|---|---|
| Class I Type A | Ni-Cr-HiC | 550 |
| Class I Type B | Ni-Cr-LoC | 550 |
| Class I Type C | Ni-Cr-GB | 550 |
| Class I Type D | Ni-HiCr | 500 |
| Class II Type A | 12% Cr | 550 |
| Class II Type B | 15% Cr-Mo | 450 |
| Class II Type D | 20% Cr-Mo | 450 |
| Class III Type A | 25% Cr-Mo | 450 |
| Milson Proprietary Grade | HiChrome | 480 |
Improved mechanical properties can be achieved through different heat treatments.
We deliver white iron components with the precision and toughness your equipment demands. Our foundry supports multiple casting methods and in-house QA to ensure consistent wear performance and reliable supply.
