Black Silicon Carbide 70# 80# 90# Abrasive Grit for Valve Se

Advantages of Black Silicon Carbide for Sandblasting
1.High hardness, efficient removal of oxide scale and welding slag
2.Iron-free, no contamination to stainless steel and alloy valve seats
3.Excellent self-sharpening property, stable cutting power during long-time blasting
4.Uniform matte surface, improves adhesion of coating and surfacing welding
5.Low particle loss, recyclable, lower overall cost
6.Chemically stable and high temperature resistant, suitable for heat-treated valves
7.Easy to clean, no residue in tiny gaps, without affecting sealing precision
