The early and original process can still be used as the measurement of the thermal decomposition of the ammonia process gas. This method employs the simple measurement of dissociation of the ammonia process gas.
Advanced Heat Treat Corp. (AHT) announced the completion of the 15,000-square-foot building expansion at its corporate headquarters in Waterloo, Iowa. Three new gas nitriding units are housed in the new addition in an effort to separate the gas nitriding equipment from the ion (plasma) nitriding units. There are plans to add a fourth gas nitriding unit by the end of the year.
JGEF Furnace installed a series of gas nitriding and tempering furnaces at a commercial heat-treatment company specializing in mold and die steel heat treatment. The horizontal gas nitriding furnace can produce a hard, clean substrate onto which a duplex layer with high hardness values is deposited. The working size of the furnace is 35.5 inches wide x 35.5 inches high x 47 inches long. The charge support design is suitable for a 3,307-pound maximum load.
Advanced Heat Treat Corp. (AHT) installed three new gas nitriding units at its corporate headquarters in Waterloo, Iowa. The investment doubles their gas nitriding capacity at this location and allows the company to expand its UltraGlow gas nitriding and UltraOx surface-treatment solutions. The three units vary in size, allowing for the accommodation of industries and applications including agriculture, automotive, construction, aerospace, firearms and oil and energy. One unit will be operational this month, and the additional two units will begin operation in February. AHT also plans to design and build an additional unit later this year.
Contour purchased a gas nitriding unit from a U.S. furnace manufacturer to expand its offerings in the automotive sector and expand deeper into the aerospace market. Contour, which will install the unit at its global headquarters in Indianapolis, Ind., in spring 2019, manufactures induction heat-treat systems and offers commercial induction processing services. The purchase of a gas nitriding unit will allow the company to expand services focusing on distortion-critical, complex parts.
JGEF Furnace of China shipped six furnaces to a Japanese heat-treating company. Four horizontal, front-loading nitriding furnaces are designed specifically for precision gas nitriding in a retort style with vacuum purge. This gas nitriding method precisely controls the case depth and nitride layer formation (including white layer) to achieve high surface hardness, improved wear resistance and longer fatigue life.
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.
SECO/VACUUM Technologies supplied a precision gas nitriding vacuum furnace to a large North American heat treater. The horizontal, front-loading furnace is designed specifically for precision gas nitriding, ferritic nitrocarburizing and post-oxidation in a retort-style furnace with vacuum purge. The ZeroFlow furnace complements a prior SECO/WARWICK gas nitriding furnace already in production at the facility.
