Stainless steel shots are widely used for deburring and brightening of the surface of aluminium alloy, zinc alloy, colorful metal and stainless steel, etc. They are of austenite structure with execellent features of high strengh and tough, low consumption, none dust, quick clean speed and good clean results. They can extend fatigue life, enhance corrosion- resisting and brighten the surface of parts. The hardness is308-509HV. Its specific gravity is 7.8g/cm³ And bulk density is 4.7g/cm³ .
