Cast Steel Grit
Types: G10/SG2.5 G12/SG2.0 G14/SG1.7 G16/SG1.4 G18/SG1.2 G25/SG1.0
G40/SG0.7 G50/SG0.4 G80/SG0.3 G120/SG0.2
The Major Technological Index:
Products Steel Grit
Chemical Composition
C 0.80～1.20%
Mn 0.35～1.20%
Si ≥0.40
S ≤0.05%
P ≤0.05%
Micro hardness GP 42～52HRC GL 53～60HRC GH 60～64HRC
Hardness Deviation Max Deviation ±3.0HRC
Microstructure Tempered Martensite or Sorbite
Density 7.6g/cm3
Applications:
Blast cleaning: Used for blast cleaning of casting, die-casting, forging, sand removal of casting, steel plate, H type steel, steel structure.
Rust removal: Rust removal of casting, forging, steel plate, H type steel, steel structure, descaling of forging.
Shot blasting: Shot blasting of profile steel, ship board, steel board, and steel material.
Shot blasting: Shot blasting of steel board, profile steel, steel structure.
Pre-treatment: Pre-treatment of surface, steel board, profile steel, steel structure, before-painting.
Steel Grit Types:
GP: Angular when new, this grit rapidly rounds off in use and its particularly suited descaling applications.
GL: Although it is harder than GP steel grit, it also loses its sharp edges during shot basting and is particularly suited
to descaling and surface preparation applications.
GH: Having maximum hardness, GH always remains angular in its operating mix. These abrasives are particularly effective in surface treatment processes and produce a uniform, etched finish, GH angular grit should only be used in wheel machines where working requirements take precedence over cost price considerations (for example with rolling mill cylinders or when a special finish is needed). Mainly used with compressed air equipment
