Chilled Iron Grit

Opta Minerals your source for Blast Cleaning Abrasives:

Chilled Iron Grit is produced from carefully selected alloy-free iron scrap that is re-carbonized in a hot blast furnace. The shot obtained by this process is then crushed into grit.

Chilled Iron Grit is a white iron structure that shatters on impact rather than wearing round. The fresh edges exposed by this process combined with a high degree of hardness result in a faster cutting/cleaning action.

A high-velocity abrasive, Chilled Iron Grit is used in blast rooms with abrasive reclaim systems and in portable pressure blast equipment, and is most often used for extremely fast blast cleaning of steel and iron components.

Advantages of Chilled Iron Grit

Wide range of grades available
Precise – tight-screen analysis of all sizes guarantees an even and consistent finish, reducing priming and painting costs
Fast – breaks down into more angular particles, resulting in a fast cut/clean
Easily recyclable
Economical alternative to steel grit abrasives
