What abrasive is best for sandblasting the surface of stainless steel workpieces?
The Mohs hardness of stainless steel is Mohs 5.5 to 6. Therefore, for surface sandblasting of stainless steel workpieces, you only need to select abrasives with higher hardness than stainless steel.
The natural abrasive garnet
Mohs hardness is above 7.5-8.0, so it is often used for sandblasting stainless steel. Our garnet abrasives are divided into sea sand, river sand and rock sand. Garnet abrasives can penetrate deep into holes and uneven parts to clean them thoroughly. Remove scale, rust, soluble salts and other contaminants. The sandblasted surface has no embeds, unfavorable convex tips and pits, and can easily obtain Sa3 sandblasting grade. The surface roughness can reach 30-80μm, with stronger coating adhesion and longer coating. service life.
