2.Steel Grit Introduction
Steel Grit is made by crushing steel shot to angular particle subsequently tempered to different hardness to cater for different application, screened by size according to SAE Standard specification.
| SAE | Application |
| G-12 G-14 G-16 | Blasting/descaling medium-to-large cast steel, cast iron, forged pieces,steel plate and rubber adhered work pieces. |
| G-18 G-25 G-40 | Cutting/grinding stone; Blasting rubber adhered work pieces; Descaling steel plate, container, ship hall before painting; Cleaning small-to-medium cast steel, cast iron, forged pieces, etc. |
| G-50 G-80 G-120 | Blasting/descaling steel wire, spanner, steel pipe before painting process; Cleaning precision castings (eg. golf blocks) |

5.Steel Grit Applications
Steel grit Cleaning
Steel shot and grit are used in cleaning applications for removal of loose material on metal surfaces. This type of cleaning is common in automotive industry (motor blocks, cylinder heads, etc.).
Steel grit Surface preparation
Surface preparation is as a series of operations including cleaning and physical modification of a surface. Steel shot and grit are used in surface preparation process for cleaning metal surfaces which are covered with mill scale, dirt, rust, or paint coatings and for physically modifying the metal surface such as creating roughness for better application of paint and coating. The steel shots are generally employed in shot blasting machines.
