Chilled Cast Iron Grit

Product Introduction

Chilled Cast Iron Grit is a high-quality abrasive material made from chilled cast iron, known for its angular, irregular shape and exceptional hardness (50-60 HRC). It is widely used for sandblasting, shot peening, and surface cleaning applications. Ideal for removing rust, paint, and scale from metal surfaces, it offers excellent durability and performance. Available in bulk packaging, it is a reliable choice for industries requiring efficient surface preparation and finishing.
