Wear resistant steels | Industeel

Wear resistant steels. For Industeel, abrasion resistant steels are much more than just the classical "wear plate": Relia® is a range of high hardness, low-alloyed martensitic steels, which obtain their hardness through intense water quenching during manufacturing.; Creusabro® is our exclusive and patented range of advanced wear and impact abrasion resistant steels.

Effect of tempering on the impact-abrasive and abrasive ...

Low-temperature tempering at temperature range of 150–250 °C is commonly used as it does not cause drastic decrease of hardness nor strength. The high hardness should be retained in order to maintain good wear resistance, specifically against abrasion. Thus, the effect of tempering on the wear resistance is of great interest.
