Technological properties

|---|---|---|
| Application areas | Organic syntheses, flue gas desulphurization, electrolytic galvanizing, plate heat exchangers, fine chemicals production, incineration plants, pharmaceutical intermediates, combustion-resistant alloy for high pressure oxygen applications. | |
| Cold Forming | VDM® Alloy 22 has higher work hardening rate than other austenitic stainless steels. This should be taken into account when selecting forming equipment. The workpiece should be in the solution-annealed condition. Intermediate annealing is necessary for major cold forming work. For cold forming above 15%, new solution annealing must be conducted. | |
| Corrosion properties | The chemical composition of Nicrofer 5621 hMoW has been designed to give it outstanding corrosion resistance in as wide a range of media as possible, both oxidizing and reducing. The high chromium content of the alloy makes it particularly suitable for oxidizing conditions, including wet chlorine gas, hypochlorite solutions or oxidizing acids. It is remarkably resistant to localized attack by halide ions, even under severe conditions of low pH and high temperatures. It resists attack in media contaminated by oxidizing chlorides such as ferric chloride or cupric chloride. Nicrofer 5621 hMoW is also resistant to many reducing media. | |
| General machinability | Nicrofer 5621 hMoW should be machined in the solution-treated condition. As the alloy exhibits a high work-hardening rate only low cutting speeds should be used compared with low-alloyed standard austenitic stainless steels. Tools should be engaged at all times. An adequate depth of cut is important in order to cut below the previously formed work-hardened zone. | |
| Heat Treatment | Solution annealing should take place at temperatures between 1,105 and 1,135°C (2,021-2,075°F). Cooling down should be accelerated with water to achieve optimum corrosion properties. Fast air cooling can also be carried out at thicknesses of less than approx. 1.5 mm. For strips as the product form, the heat treatment can be performed in a continuous furnace at a speed and temperature that is adapted to the strip thickness. In each heat treatment, the aforementioned cleanliness requirements must be observed. | |
| Hot forming | The material can be hot-formed in a temperature range between 1,100 and 900 °C (2,012 °F-1,652 °F) with subsequent rapid cooling down in water or air. Heat treatment after hot forming is recommended in order to achieve optimal properties. For heating up, workpieces should be placed in a furnace that is already heated up to the target value. | |
| Other | Nicrofer 5621 hMoW has a face-centered cubic structure. | |
| Welding | It must be ensured in the welding process that work is carried out using targeted heat application, low heat input and rapid heat extraction. The interpass temperature should not exceed 120°C (248 °F). In principle, welding parameters must be checked. | |
