High Light Cold Rolled Stainless Steel Sheet ，Bright Surface AISI 439 Sheet ，Corrosion Resistant 439 Stainless Steel Sheet
EN 1.4510 DIN SUS439m AISI 439 Stainless Steel Sheet
The composition of 439 stainless steel has been balanced to provide a completely ferritic structure at all temperatures, ensuring maintained ductility after welding and excellent resistance to intergranular corrosion.
Unlike similar ferritic stainless steels such as 430 and 434 alloys, which are susceptible to brittle martensite formation after welding and intergranular corrosion sensitivity, 439 stainless steel does not require annealing after welding to restore ductility or provide intergranular corrosion resistance.
Key Advantages
  • Excellent resistance to stress corrosion cracking
  • Superior weldability characteristics
  • High thermal conductivity
  • Low thermal expansion properties
  • Low cobalt content for nuclear applications
These properties make 439 stainless steel an ideal choice for many industrial applications. For shell and tube heat exchangers where carbon steel shells are used with 439 tubes, the close match of thermal expansion coefficients may eliminate the need for expansion joints.
Application Areas
When application temperatures exceed the capabilities of 409 stainless steel, 439 stainless provides excellent oxidation and corrosion resistance for automotive exhaust system components and residential furnace primary heat exchangers.
