| Application areas | Nicrofer 3718 finds wide application in high-temperature processes: fans operating at high temperatures in carburising furnaces resisting carburisation, boxes and baskets used in carburising resisting carburisation and showing weight savings when compared with cast boxes, hangers, hooks and conveyor chains used to carry vitreous-enamelled components during firing resisting oxide spalling so that oxide does not fall on the enamel, combustion tubes resisting oxidation to carburisation and alternating oxidising and carburising conditions, jigs and fixtures used in furnace brazing and wire mesh belts to carry components in heat-treatment processes, thermocouple sheaths resisting carburisation and nitriding, flare-stack tips resisting alternating conditions, components handling cracked ammonia. | |
| Cold Forming | Cold working should be carried out on annealed material. Nicrofer 3718 has a similar work-hardening rate compared to austenitic stainless steel and the forming equipment must be adapted accordingly. When cold working is performed, interstage annealing may become necessary. After cold reduction of more than 15%, final annealing is required before use, in so far as the creep-strength is important. Bending property and formability is given even with oxidised sheets. Nevertheless the bending radius should be 3 times sheet thickness. | |
| Corrosion properties | The nickel-chromium-iron alloy Nicrofer 3718 containing about 2% silicon is a general-purpose heat-resisting material. It has good oxidation resistance up to about 1000°C, particularly under cyclic conditions of heating and cooling. It also has excellent resistance to carburisation and is widely used in industry under such conditions. Its resistance to nitrogen-containing atmospheres where oxygen content is low makes them suitable for environments such as cracked ammonia. | |
| General machinability | Nicrofer 3718 should be machined in the annealed condition. As the alloy is susceptible to work-hardening, a low cutting speed should be used and tools should be engaged at all times. Heavy feeds are important in betting below the work-hardened 'skin'. | |
| Heat Treatment | Annealing should be carried out in the temperature range 1020 to 1120°C (1870 to 2050°F). Water quenching is essential for maximum creep resistance. During any heating operation, the precautions outlined earlier regarding cleanliness must be observed. | |
| Hot forming | Nicrofer 3718 may be hot-worked in the range 1150 to 950 °C (2100 to 1740 °F). Cooling should be by water quenching or as fast as possible. Annealing is recommended after hot working to ensure maximum corrosion resistance and optimum structure. The material may be charged into the furnace at maximum working temperature. | |
| Other | Nicrofer 3718 is a solid solution alloy with small amounts of precipitated titanium nitride and carbide as well as carbonitrides in the austenitic matrix. | |
| Welding | Nicrofer 3718 can be welded by GTAW, plasma arc and SMAW processes. Prior to welding, material should be in the annealed condition, clean and free from scale, grease, marking paints etc. A zone approximately 25 mm (1 in) wide on each side of the joint should be ground to bright metal. Interpass temperature should not exceed 150°C (300°F). Neither pre- nor post-weld heat treatment is required. | |
