Service Heat Treating, a commercial heat-treating company located in Milwaukee, Wis., has developed an alternative heat-treatment process known as WearAllthat has shown to provide better wear resistance than carbonitriding for a number of critical-service components.
SECO/VACUUM (SVT), a SECO/WARWICK Group company, received an order from a U.S. manufacturer for a precision gas nitriding furnace with ZeroFlow technology. The furnace will allow the company to offer engineered steel surfaces that exceed, in many cases, its competitors’ product performance. The company manufactures a range of transportation components. In addition to gas nitriding, the furnace has ferritic nitrocarburizing capability and pre- and post-oxidation. It also has the ability to clean temper and clean anneal to temperatures up to 1400°F.
Ferritic-nitrocarburizing (FNC) processing is becoming a more common alternative to coating processes that require improved mechanical properties and resistance to corrosion, often on plain-carbon and low-alloy steels.
Atmosphere Annealing, a division of Premier Thermal Solutions, recently added ferritic nitrocarburizing (FNC) to its process offerings in Lansing, Mich. FNC is widely used in the agriculture, automotive, energy, heavy equipment, heavy truck and rail industries, all of which are supported by Atmosphere Annealing. FNC is typically used on plain-carbon steel components and is known for providing a high level of wear resistance, low distortion, improved fatigue properties and greater corrosion resistance. Depending on requirements, FNC is often used as an alternative to carburizing and carbonitriding.
Last but certainly not least, as the saying goes, is our discussion of gas nitriding and nitrocarburizing process simulators and how they are used to predict and control these case-hardening processes. Let's learn more.
Advanced Heat Treat Corp. (AHT) purchased a gas nitriding unit to expand its capacity for UltraGlow gas nitriding and UltraOx surface-treatment solutions at its corporate office and service center in Waterloo, Iowa. The large, state-of-the-art, high-temperature gas nitriding unit will also allow for increased capacity of gas ferritic nitrocarburizing (FNC) and stress relief. AHT plans on hiring part-time and full-time laborers to deal with the added capacity.
Z Capital Partners, the private-equity management arm of Z Capital Group, announced an agreement to acquire Atmosphere Annealing (AA) and NitroSteel (NS), collectively known as Premier Thermal Solutions, from Gerdau S.A.
You have heard the terms carbonitriding and nitrocarburizing and know they are two different case-hardening processes, but what are the real differences between them?
