High Chrome Casting

These irons produce a more continuous structure of iron-chromium carbides.

After heat treatment these irons have a hardness range of 600-650 BHN

All the white irons are difficult to machine, however advances in ceramic machining tips have vastly improved the prospects.

They are nearly impossible to drill and tap and hace steel inserts cast into the casting to allow drilling and tapping to take place.

Ni Hard Casting

In these irons a development of iron-chromium carbides produce a tougher more abrasion resistant iron.

The variation of carbon content effects the toughness and abrasion resistance.

Greater carbon increases the resistance to abrasion, however at the loss of toughness and vice versa lowering the carbon increases toughness but decreases the resistance to wear.

Hardness ranges dependent on section thickness can be between 450-600 BHN

The use for Ni-Hards is in pulverising, crushing and impact wear plates also in heavy duty pump casings and impellers for slurry and gravel applications.
