Frequently Asked Questions
Heat-treating operations may use nitrogen, argon, hydrogen, helium, carbon dioxide, ammonia, methane, and acetylene as process gases. Generated atmospheres using feedstock such as methane, propane and butane and synthetic atmosphere such as nitrogen-methanol, nitrogen-hydrogen blends are also widely used. The appropriate gas, generated or synthetic atmosphere depends on whether the process involves carburizing, carbonitriding, annealing, hardening, nitriding, inerting, or other metallurgical treatments.
Nippon Sanso Matheson supplies pure gases, bulk gases, cylinders, generated atmospheres, blended atmospheres, synthetic atmospheres, atmosphere-generation chemicals, storage systems, monitoring, and application support for heat-treating operations. Nippon Sanso Matheson engineers also provide expert application support such as gas sampling, atmosphere analysis, safety audits, and process troubleshooting.
A controlled furnace atmosphere can prevent oxidation and decarburization, control carbon potential, enhance surface properties, and support repeatable metallurgical outcomes. Variability in gas purity, atmosphere composition, or supply can contribute to scrap, rework, and lost productivity.
The gas supply, storage system, distribution piping, and furnace atmosphere can be evaluated for contaminants or incorrect composition. Nippon Sanso Matheson application engineers use analytical equipment and process expertise to help identify atmosphere-related quality issues and reduce process variability.
Endothermic gas is widely used for carburizing, carbonitriding, and neutral hardening of steel. Endothermic gas is a mixture of nitrogen, hydrogen and carbon monoxide generated by a high temperature catalytic conversion of natural gas/propane with air. Nippon Sanso Matheson supplies methane, propane, and butane for endothermic gas generators and offers Endogreen™ generators as an alternative to conventional endothermic gas-generation systems.
A synthetic atmosphere is created by supplying and controlling selected gases or feedstocks rather than relying only on a conventional atmosphere generator. Nippon Sanso Matheson offers methanol-and-nitrogen storage and supply solutions for heat treaters requiring a lower carbon monoxide value than conventional endothermic gas may produce.
Nippon Sanso Matheson’s quality program and heat-treating expertise can help customers address applicable requirements, including the requirements heat treating companies may have to meet NADCAP accreditation. Nippon Sanso Matheson also has expertise on NFPA 86 and NFPA 55 requirements, which may include parallel vaporization, low temperature shut offs, and gas level alarms. Nippon Sanso Matheson’s support includes system design, regulatory guidance, gas analysis, safety audits, and documentation related to its supplied solutions.
Available options include high-pressure cylinders, liquid cylinders, bulk systems, microbulk systems, gas blending, and on-site gas or furnace-atmosphere generation. Additionally, Nippon Sanso Matheson can provide 10-packs of acetylene for vacuum carburizing applications. Nippon Sanso Matheson engineers customized storage and delivery systems based on capacity, pressure, atmosphere, safety, and growth requirements.
Pressure, temperature, gas composition, and inventory monitoring can help operators identify supply or atmosphere issues before they affect production. Nippon Sanso Matheson provides monitoring, analytical systems, and control-integration support for improved process visibility and atmosphere control, including the ability to measure residual gas atmosphere in furnaces.
Nippon Sanso Matheson provides industrial gases, atmosphere feedstocks, generation systems, storage, monitoring, gas analysis, engineering, compliance support, and process troubleshooting.
