5. Conclusion

Austenitic-ferritic steels stand out as essential materials, particularly in the chemical industry, thanks to their remarkable resistance to corrosion and abrasion. The precision with which they are produced, the precautions required during welding and forming, and their high mechanical properties, reflect the technical sophistication and adaptability of these steels. Their growing popularity in industrial circles testifies to their effectiveness and relevance in applications requiring both mechanical strength and durability in corrosive environments. The operating temperature range from – 50°C to +300°C underlines their ability to meet the demands of a wide variety of industrial environments.
