What is the difference between steel shot and steel grit? Let's first understand their similarities: 1. In the national standard GB/T18838.3-2008, the main detection chemical composition and content of steel shot and steel grit are basically the same; 2. Owen Steel shot Owen The life is 2300-3500 times (the national standard steel shot is: 2000-2800); 3. The metallographic structure is uniform tempered martensite or tempered troostite.
Differences: 1. Shape: steel shot is round, steel grit is angular with radian; 2. Hardness: steel shot hardness is 40-51HRC, steel grit hardness is divided into three types (40-51HRC, 54-61HRC, ＞60HRC); 3. Roughness: The surface of the workpiece is relatively smooth when the steel shot is shot, and the steel grit is relatively rough.
