Product Description
JIS G4305-2012 SUS439 Stainless Steel Coil Strip
439 stainless steel features a balanced composition that maintains a completely ferritic structure across all temperatures, ensuring excellent ductility after welding and superior resistance to intergranular corrosion. Unlike similar ferritic stainless steels such as 430 and 434 alloys, 439 stainless does not require post-welding annealing to restore ductility or corrosion resistance.
Key Advantages
- Excellent resistance to stress corrosion cracking
- Superior weldability without post-welding annealing requirements
- High thermal conductivity with low thermal expansion characteristics
- Low cobalt content ideal for nuclear applications
- Good oxidation and corrosion resistance for high-temperature applications
