It’s simple: We last longer. No other commercial products can perform as well as our EndurAlloy® process in high wear, erosion, or corrosive environments. The EndurAlloy® case depth does not experience pits, separation, collapse, flaking, or disbondment which ensures a longer run life than the competition.  Unlike some of the competition EndurAlloy® products can withstand high temperatures and maintain the original ID after processing.

EndurAlloy® is a surface engineering thermo-chemical (thermal-diffusion) process based on the CVD principles where boron atoms, being in the gas phase, deposit and diffuse into the heated steel surface with consequent formation of iron borides (FeB and Fe2B) with their growth and consolidation yielding a hard and chemically inert case depth. It is also often referred to as diffusion alloying and pack cementation.

EndurAlloy® is a surface engineering advanced case depth where, similarly to CVD coatings and as opposed to many “conventional” coatings, the case depth forms as a new compound through the combined thermo-chemical reaction, diffusion, and high-temperature consolidation processes. We use a special composition of powders, mixed to create through the gas phase, a case depth with “new” composition occurring with contact with steels or ferrous alloys at high temperatures. As opposed to many conventional coating processes, the diffusion-related bonding provides excellent adhesion of the iron boride case depth to the substrate with no delamination or peeling-off.

Resulting from the thermal diffusion process, the EndurAlloy® surface is a well consolidated layer consisting of iron borides with high hardness and high chemical inertness. It is highly resistant to many corrosive gases and liquids, e.g. to many acids, alkalis, high temperature-high pressure water steam with high contents of salts, H2S, CO, CO2, hydrocarbons, etc. We have various test documents to support the corrosion resistance of our products.

Endurance Technologies carries an inventory of EndurAlloy® Tubing at our Calgary yard as well as yards throughout Saskatchewan (Kindersley, Swift Current, Estevan) and Alberta (Provost, Brooks, Bonnyville, Lloydminster, Grande Prairie, Drayton Valley, and Peace River). Turnaround times for custom orders will vary and we encourage you to contact our sales team to discuss.

It is not recommended since the new surface is extremely hard, and its machining can be done only using expensive special diamond tooling and dedicated processing.

Please contact our office for details.

All carbon and low-alloy steels, majority of stainless steels (e.g. 300 and 400 series stainless steels), Ni-rich ferrous alloys, 17-4ph, cast steel and forged steel, as well as cast irons. We have other processes that can be used on other materials. Depending on substrate material and process parameters selected, the case depth varies from 0.001” to 0.012” (25 to 300 µm). Please, contact our office with your specific requirements.
