Technological properties

|---|---|---|
| Application areas | Automotive industry, Decorative Applications, Hydraulic Equipment, Petrochemical industry, Food and Beverage industry, Mechanical engineering, Cutlery, Blades | |
| Corrosion properties | Average - Good corrosion resistance in moderately corrosive environments that are free of chlorides, such as soaps, detergents and organic acids. Good resistance in oxidising atmospheres up to temperatures of about 600 °C. 1.4021 is not resistant to intergranular corrosion in the asdelivered or as-welded conditions. PRE = 12.0 – 14.0 | |
| General machinability | Good - The machinability of this grade of stainless steel is directly related to its hardness. 1.4021 machines similar to carbon steels of the same hardness. Although it must be realised that the machining parameters will vary depending on the structure/hardness of the steel. | |
| Heat Treatment | Soft annealing: 745-825°C (Cooling in furnace, air) - Hardening: 950-1050°C and quenching in air, polymer, oil - Tempering: 600-700°C | |
| Hot forming | It is formable at 800-1100°C | |
| Processing history | Quenched and tempered, QT 800 | |
| Welding | Good - Preheating of the work piece to a temperature within the range 100 °C – 300 °C is required as well as a post weld tempering treatment when welding is performed using a matching filler material. Generally, Novonit® 4551 is recommended when a filler material is required. Tempering at 650 °C after welding is recommended to restore some of the ductility in the weld zone. When using an inert or protective shielding gas during welding, care must be taken to avoid use of any hydrogen or nitrogen containing gases since contamination of the weld with nitrogen or hydrogen will adversely affect the mechanical properties. After welding the work piece must be cooled to below the martensite start (MS), temperature of approximately 120 °C before being tempered. | |
