Stainless steel 1.4465

✅ General Technical Characteristics

Stainless steel 1.4465 is a high-alloy corrosion-resistant steel with excellent resistance to aggressive environments. It belongs to the category of duplex steels, which ensures high strength, good weldability, and enhanced resistance to stress corrosion. Due to the balance of austenitic and ferritic structures, this alloy exhibits improved mechanical properties compared to traditional stainless steels.
Main Characteristics:
High corrosion resistance in aggressive environments.
Excellent mechanical strength and hardness.
Good weldability and machinability.
Heat resistance and stability at high temperatures.
Resistance to stress corrosion and pitting corrosion.
