| Corrosion properties | Average - Good corrosion resistance in moderately corrosive environments that are free of chlorides, such as soaps, detergents and organic acids. Good resistance to water and steam. 1.4034 is not resistant to intergranular corrosion in the as-delivered or as-welded conditions. Due to the precipitation of chromium carbides and the formation of chromium depleted regions adjacent to these precipitates, 1.4034 should not be used in the soft annealed or over tempered conditions if corrosion resistance is an issue. Optimal corrosion resistance is thus achieved in the hardened condition with a polished surface finish. PRE = 12.5 – 14.5 | |
| General machinability | Poor - The machinability of this grade of stainless steel is directly related to its hardness. 1.4034 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 | 1.4034 can be soft annealed by holding at a temperature in the range 750 °C to 850 °C followed by slow cooling in an oven or in air. This steel may be hardened by heating to 1050 °C followed by rapid cooling in air or oil. After hardening and stress relieving at 200 °C. | |
| Hot forming | It is formable at 800-1100°C | |
| Processing history | Quenched and tempered QT 800 | |
| Welding | Poor - Although 1.4034 is generally not welded, it is soldered in some instances. | |
