Product Description

439 Stainless Steel Properties & Sheet

439 stainless steel features a carefully balanced composition that provides a completely ferritic structure at all temperatures. This unique formulation prevents ductility loss after welding and offers exceptional resistance to intergranular corrosion.

Superior Performance Advantages

Eliminates brittle martensite formation after welding (unlike 430 and 434 alloys)
No post-welding annealing required to restore ductility or corrosion resistance
Excellent resistance to stress corrosion cracking
Superior weldability characteristics
High thermal conductivity with low thermal expansion
Low cobalt content ideal for nuclear applications
Excellent oxidation and corrosion resistance for high-temperature applications
