Toolox wear plates can take the heat and deliver outstanding performance

When steel is exposed to heat, it loses its hardness and resistance to wear. What if we could offer you a steel plate like our renowned Hardox® wear plate that even endures elevated temperatures?

Toolox 33 in hot slag bucketToolox®, initially developed for moulding of plastic parts, also possesses the properties required for use at elevated temperatures in environments where the steel is exposed to high forces and wear. The secret behind Toolox lies in a unique production process that allows it to keep its properties during demanding use — up to 590°C (1,094°F) — where it retains approximately 80 percent of its original hardness. And Toolox is dimensional stable meaning it holds a minimum of internal stresses, making it incredibly workshop friendly.

The right combination of hardness and toughness

Tool steel used in industries and processes involving high work temperatures and high wear must be hard and tough at the same time. Toolox features high thermal conductivity values and comes in three hardness levels ranging from 300 HBW to 450 HBW. So you’re sure to find the optimum solution for your application for use at elevated temperatures.

Applications

Toolox’s high-temperature properties make it a perfect wear plate in the metal or cement industries, or for power plants and other areas where slag and other substances with very high temperatures are handled.
