TiC stands for Titanium Carbide, a steel-bonded hard alloy. Standard foreign trade terms: TiC insert / TiC embedded.
Principle: Metallurgical casting process. TiC hard alloy rods/cylinders are pre-positioned in the sand mould before casting. Molten high manganese steel (Mn18Cr2 commonly used) is poured into the mould. After cooling, metallurgical bonding forms between TiC rods and the matrix, rather than simple adhesion. It combines the toughness of the matrix and the superior wear resistance of TiC.
✅ Advantages
- Wear service life: Under identical working conditions, service life is 2~3 times longer than standard Mn18Cr2 high manganese steel. It delivers outstanding performance for highly abrasive materials such as high-silica granite and quartzite.
- The matrix retains the toughness of high manganese steel. Compared with solid hard alloy parts, it offers better impact resistance and is less prone to catastrophic fracture.
- Uniform wear. The liner profile remains stable for longer, maintaining consistent product size and reducing downtime for replacement.
- Lower overall cost per ton of crushed material. Although the unit purchase price is higher, fewer replacements are required.
Inspection Points (Quality Control for Overseas Customers)
- Insert layout: TiC inserts are placed only in high-wear zones instead of scattered evenly across the whole surface. Layout is optimized based on wear simulation analysis.
- Bonding interface: Metallographic examination is required to verify metallurgical fusion between TiC rods and the matrix, with no obvious gaps.
- Non-destructive testing: UT and MT to inspect for internal cracks and porosity.
- Drop weight impact test: To verify the anti-detachment performance of alloy inserts.
