Buy Chromite | Sand

: Typically ranges from AFS 30 to 55 .

This guide outlines the critical factors for purchasing industrial chromite sand, a high-performance mineral primarily used in foundry and metallurgical applications for its extreme heat resistance.

) Content : Ideally and strictly under 3%. Low silica prevents chemical reactions with molten steel that cause "sand burn" or sticking.

) Content : Look for a minimum of . Higher grades (46%+) offer better refractoriness and thermal stability. Silica ( SiO2cap S i cap O sub 2
