| Corrosion properties | Very Good - 1.4435 displays excellent resistance to corrosion in most natural waters (urban, rural and industrial), even at moderate chloride and salt contents. In the food, beverage and agricultural sectors, 1.4435 displays excellent corrosion properties. This grade of stainless steel is also resistant to corrosion in various acid environments. Due to its low carbon content, 1.4435 is still resistant to intergranular corrosion after welding, i.e. in the sensitised condition. Corrosion testing in accordance with the following corrosion testing specifications, is thus sufficient to establish resistance to corrosion: AFNOR NF 05-159, ASTM A262-75. Practice E, DIN EN ISO 3651-2. The higher molybdenum addition compared to 1.4404, makes 1.4435 more resistant to corrosion in reducing acids and chloride containing media. (PREN = 25.3 – 30.7) | |
| General machinability | Average - For applications which require machining, the NIRO-CUT 4435 grade is recommended since the composition and production route followed to produce this grade compensates for the work hardening tendency of the material. Due to the low carbon content and stable microstructure, NIRO-CUT 4435 can be readily machined. | |
| Heat Treatment | Solution annealing: 1020-1120°C (water, air) fast cooling | |
| Hot forming | It is formable at 900-1200°C | |
| Processing history | Solution Annealed | |
| Welding | Excellent - 1.4435 is readily weldable using all welding processes. Should a filler material be required, Novonit 4430, can be used. Maximum inter-pass temperature during welding is 150°C. Heattreatment after welding is not necessary, and even large sections are resistant to intercrystalline corrosion after welding, due to the low carbon content. Any scale or heat tint that results from welding or high temperature processing must either be mechanically or chemically removed followed by a suitable passivating treatment to restore the corrosion resistance. | |
