Mining is a key industry for many economies worldwide. The increasing number of mining projects has generated a growing demand for equipment and trucks for digging, conveying, and transporting equipment and minerals. Heat treating of many components made from hard alloys used in the mining industry is essential. These components, which are exposed to harsh environments and chemicals, need to able to sustain heavy usage and be available in remote areas where the nearest repair shop could be thousands of kilometers away.

Nitrex has developed process- and application-specific know-how to help mining suppliers and services providers ensure that mining tools and equipment meet or exceed the performance and design expectations of the most mission-critical applications.

Nitriding Systems

Nitrex nitriding / nitrocarburizing systems and technologies deliver superior quality and performance, improving the wear and corrosion resistance of a number of steel types.




Vacuum Furnaces

From vacuum brazing to precipitation hardening furnaces









Control system upgrades and retrofits for all types of furnaces.







Hard metals such has INCONEL and INCOLOY alloys are often used for applications, such as pumps, piping and separation machinery, as well as drilling equipment and the construction of downhole shafts. These components are subject to both high pressure and heat, so materials need to be strong while also providing excellent resistance to abrasion, oxidation, and corrosion. The hard conditions of mining sites make the choice of alloys resistant to oxidizing chemicals and high-temperature oxidizing gases critical.
