Application areas | Automotive industry, Building and construction industry, Chemical industry, Food and beverage industry, Aviation and aerospace, Mechanical engineering | |
Corrosion properties | Good - 1.4541 displays excellent resistance to corrosion in most natural waters (rural and industrial), provided the chloride, salt and concentrations of hydrochloric and organic acids are low. 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, are sufficient to establish resistance to corrosion: AFNOR NF 05-159, ASTM A262-75. Practice E, DIN EN ISO 3651-2. (PREN = 17.0 – 19.0) | |
General machinability | Poor - The formation of titanium carbo-nitrides in 1.4541 alters the machinability of this stainless steel compared with the low carbon, titanium free variants, like 1.4307. | |
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 - 1.4541 is weldable with all processes, except gas welding, either with or without the use of filler material. If the use of a filler metal is required, then the use of Novonit 4316 or 4551 would be recommended. Post weld heat treatment is not necessary. Maximum inter-pass temperature 200°C. Any heat tint that forms must be removed by pickling or suitable mechanical process followed by passivating to restore corrosion resistance. |
