Characteristics of EN 1.4313 / UNS S41500 Stainless Steel
- High Strength & Good Toughness: Achieves an excellent combination of high tensile strength and superior toughness after heat treatment.
- Superior Weldability: The low carbon content significantly improves weldability over standard martensitic grades, minimizing cracking.
- Enhanced Corrosion Resistance: Offers good resistance to corrosion in freshwater, steam, and various mild chemical environments.
- Excellent Low-Temperature Properties: Retains good impact strength and ductility at sub-zero temperatures.
- Hardenable for Versatility: Its mechanical properties can be precisely tailored through heat treatment to meet specific application requirements for strength, hardness, and toughness.
- Good Fatigue Resistance: The balanced properties provide excellent resistance to fatigue failure, making it ideal for dynamically loaded parts like turbine blades, shafts, and valves.
- Good Machinability: Can be readily machined in both the annealed and quenched & tempered conditions, allowing for the fabrication of complex components.
- Cost-Effective Performance: Provides a high-performance, long-lasting solution for demanding engineering applications where carbon steels are inadequate.
