Chrome Grit

A high-strength blasting medium produced by adding chromium to standard steel, melting at high temperature, crushing and quenching. Excellent workability, economy, consistent process quality and a clean, environmentally sound operation.

Hardness (New)

≈ 675 HV (58 HRC)

Hardness (Operating Mix)

≈ 720 HV (61 HRC)

Density

≥ 7.3 g/cm³

Microstructure

Martensite / Chromium Carbides

Features

High-strength medium with excellent machinability; produces an even, clean and uniform surface finish
Superior workability compared with other abrasives under identical conditions
Over 20× the life of aluminium oxide and 2.5× that of steel grit — highly economical
Very clean working environment with no abrasive corrosion

Applications

Removal of grinding marks on stainless products — replaces acid treatment
Removal and stripping of Teflon coating on frying pans and kitchenware
Pre-treatment for thermal spray coating
