Beschreibung

1.4301 is the standard for the austenitic grades of stainless steel due to its good corrosion resistance, ease of formability and fabrication coupled with its aesthetic appearance in the polished, ground and brushed conditions. Since 1.4301 is not resistant to intergranular corrosion in the welded condition, 1.4307 should rather be specified if welding of larger sections is required and no solution annealing treatment after welding can be performed. Surface condition plays an important role in the corrosion resistance of this steel with polished surfaces exhibiting far superior corrosion resistance compared with rougher surfaces on the same material.

Corrosion properties

Good - Due to the moderate carbon content of 1.4301, this grade of stainless steel is prone to sensitisation. The formation of chromium carbides and the associated chromium depleted regions that form around these precipitates make this grade of steel susceptible to intergranular corrosion. Although no danger of intergranular corrosion exists in the supplied (solution annealed) condition, intergranular corrosion may occur after welding or high temperature processing. 1.4301 is resistant to corrosion in most environments provided the chloride and salt concentrations are low. 1.4301 is not recommended for applications where it comes into contact with sea water, nor is it recommended for use in swimming pools. PRE = 17.5 – 21.36

General machinability

Average - For applications which require machining, the NIRO-CUT® 4301 grade is recommended since the composition and production route followed to produce this grade compensates for the work hardening tendency of the material.

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. Since this grade of steel is susceptible to precipitation of chromium carbides, care must be taken to limit the time spent in the temperature range 450 °C to 850 °C, both during fabrication and service.

Hot forming

It is formable at 900-1200°C

Welding

Excellent - 1.4301 is weldable with or without the use of filler material. If the use of a filler metal is required, then the use of Novonit® 4316 (AISI 308L) would be recommended. Maximum interpass temperature 200 °C. Post weld heat treatment is not necessary.
