Steel Shot and Steel Grit

Supply steel shots & grits from China.

Steel Shots & Grits are made of tempered martensite, with moderate hardness, excellent elasticity, wear-resistant, give less dust, longer recycle life, low cost, extensively used for shot peening to give residual stress in the surface layer of components for fatigue life enhancement and suppression of stress corrosion cracking and descaling and cleaning up surfaces of castings, steel parts and mechanical work-pieces prior coating. They are also extremely ideal materials for cutting granite.
