Offering the best wear-resistance among high-chromium-based cast iron consumables

These are major consumable parts used at coal pulverizing mills for boilers and firing kilns. However, in recent years, longer-life parts have been required in order to reduce maintenance costs of these wear parts.


Life twice as long as Ni-Hard IV that has been conventionally used

18Cr-based cast-iron material provides the top level of hardness through the effect produced by the proper mixing of C and Cr, special heat treatment, and addition of special elements.

Maintained at stable hardness

Thin-wall parts and thick-wall parts such as rollers do not lose hardness loss from surfaces to their core.

High hardness, but less toughness loss

Higher hardness but the same toughness as conventional high-chromium materials.


Pulverizing of coal

Pulverizing of blast furnace slag

Pulverizing of calcium carbonate

Preliminary crushing of clinker
