Brief Introduction

The guide roll made of TiC-based Cemented Carbides are the main consumptive parts, completed together with cemented carbide roll-rings in rod and wire milling in steel industry to ensure that the heated steel can be exactly guided into roll groove to prevent steel winding and tail swing.

TiC-based Cemented Carbides and their mechanical properties

Grade Main Components Density
HRA hardness (20C) N/mm2 
Transverse Rupture Strength 
Young’s modulus
Coefficient of thermal expansion 10-6 Applications
HTN-1 (Ti,W)C - Ni 6.40~6.70 ≥84.5 ≥1500 370 7.0 Guide roll
HTN-2 (Ti,W)CN- Ni 6.35~6.55 ≥83.0 ≥1600 360 7.0 Guide roll

  1. Excellent crack resistance.
  2. Good self-lubrication ability and low friction factor
  3. Good wear and corrosion resistance
  4. Resistance to thermal impact better than that of alloy steel, with a life time 20~50 times that of the latter.
  5. Non-magnetic, not easy to be adhered by metal.
  6. Smaller specific gravity, good acceleration property, prolonging bearing performance life
