| Corrosion properties | Due to the low carbon content of 1.4307, there is virtually no tendency for the formation of chromium carbides and the associated chromium depleted regions that would form around these precipitates. Resistance to intergranular corrosion is thus far superior to 1.4301. Since this grade of stainless steel 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 - 1.4307 is resistant to corrosion in most natural waters and urban and rural atmospheres, provided that the chloride and salt contents are low. This grade of stainless steel is not resistant to sea water and as such must not be used in any sea water applications. As with 1.4301, this steel is not suited for use in swimming pools or swimming pool environments. Resistance to reducing acids is also confined to low concentrations and low temperatures. Optimal material properties are realised after solution annealing in the temperature range . PRE = 16.5 – 20.26 | |
| General machinability | For applications which require machining, the NIRO-CUT® 4307 grade is recommended since the composition and production route followed to produce this steel compensates for the work hardening tendency of the material. The following cutting parameters are thus proposed as a guideline when using coated hard metal cutting tools. | |
| Heat Treatment | Optimal material properties are realised after solution annealing in the temperature range 1000 °C – 1100 °C followed by rapid cooling in air or water. During operation and fabrication, the time spent in the temperature range 450 °C – 850 °C must be minimised to avoid embrittlement. In the solution annealed condition | |
| Hot forming | It is formable at 900-1200°C | |
| Processing history | Solution Annealed | |
| Welding | 1.4307 is weldable with or without the use of filler material. If a filler metal is required, then the use of Novonit® 4316 (AISI 308L) would be recommended. Post weld heat treatment is not necessary | |
