IGE offers a range of axial, radial, and forward curved fan designs that are suitable for nitriding processes of various scales and configurations. IGE offers innovative shaft sealing methods that ensure process stability, energy efficiency, and improved safety and offers both air-cooled and water-cooled designs. IGE also offers direct-drive sealed motors that offer vacuum-level seal quality as well as innovative, positive-pressure-atmosphere seal enclosures to maximize atmosphere & process control.
IGE’s high-quality fabrication and 3-step precision balancing process mean our fan units can more than double the usable service life compared to common competitor equipment and significantly reduce operating costs and maintenance work.
Nitriding is a heat-treating process that aims to harden the surface of steel by introducing nitrogen into the surface layer. Nitriding enhances surface hardness, wear resistance, and fatigue strength. Low-carbon steel alloys are commonly case hardened via nitriding, but the process also translates well to aluminum, titanium, and other more exotic alloys for high performance applications. This makes nitriding a common process in the aerospace & defense and automotive industries for parts like bearings, valves, nozzles, cylinder liners, etc.
There are many nitriding processes including: gas nitriding, salt nitriding, and plasma nitriding.
Given high temperatures, typically 885-1150°F (475-620°C), and highly toxic, flammable process gases (e.g., ammonia), high-quality, well-engineered atmosphere-moving equipment is critical. At best, incorrect or lower quality equipment will lead to inconsistent process conditions, low energy efficiency, and elevated maintenance costs. At worst, such equipment can create real safety issues for your team and generate excessive quality waste & asset downtime.
Nitriding is similar to Carburizing in that it’s a surface-hardening heat-treating process but differs in that case depths are usually shallower and quenching is often unnecessary. There are also hybrid processes, carbonitriding and nitrocarburizing, that can yield unique material characteristics.
