G40 Steel Grit is a fine steel grit abrasive designed for light to medium blasting, controlled rust removal and fine surface preparation. Its smaller particle size provides better surface control and produces a finer, more uniform blasting profile compared with coarse steel grit. G40 steel grit is suitable for small and medium metal parts, precision steel components, welded parts, machinery components and applications where the surface needs to be cleaned without excessive roughness before coating or painting.
Steel grit is produced by melting high-quality steel, atomizing it into steel shot, crushing the shot into angular particles, and then screening and heat-treating the material according to required hardness and size.
During production, the steel grit is classified by sieve analysis and inspected for chemical composition, hardness, density and particle size distribution. This helps ensure stable cutting performance and consistent surface roughness during blasting.
G40 steel grit is suitable for fine blasting, light rust removal, surface cleaning and controlled coating preparation. It is commonly used for small and medium metal parts, machinery components, welded parts, precision steel parts and surfaces that require a cleaner, smoother blasting result before painting or coating.
Packed in steel drums or palletized packaging.
25 kg bags or jumbo bags.

G40 steel grit is a fine angular abrasive used for light surface cleaning, controlled rust removal and surface preparation before painting or coating. Compared with coarser steel grit sizes such as G18 and G25, G40 creates a finer and more uniform surface profile.
G40 steel grit is suitable for small and medium metal parts, steel components, machinery parts, welded parts and surfaces that require moderate cleaning with better surface control.
G25 steel grit has a larger particle size and provides stronger cutting power with a deeper surface profile. It is suitable for general rust removal, descaling and standard coating preparation.
G40 steel grit is finer than G25. It provides a more controlled cleaning effect and creates a smoother, finer surface profile. It is suitable for applications where the workpiece needs light to medium cleaning without excessive roughness.
