High Light Ferritic Structure Stainless Steel SheetIntergranular Corrosion Resistant 439 Stainless SteelLow Thermal Expansion Cold Rolled Sheet
439 Stainless Steel Sheet 1.4910 439 Inox Sheet 2D Finished
The composition of 439 stainless steel has been precisely balanced to deliver a completely ferritic structure across all temperature ranges. This engineering ensures no loss of ductility after welding and provides exceptional resistance to intergranular corrosion.
Unlike similar ferritic stainless steels such as 430 and 434 alloys—which are susceptible to brittle martensite formation post-welding and intergranular corrosion sensitivity in as-welded conditions—439 stainless steel maintains its integrity without requiring post-weld annealing to restore ductility or corrosion resistance.
This alloy offers excellent resistance to stress corrosion cracking, superior weldability, high thermal conductivity, and low thermal expansion characteristics, making it an ideal choice for numerous demanding applications.
In shell and tube heat exchangers where carbon steel shells are paired with 439 tubes, the closely matched thermal expansion coefficients may eliminate the need for expansion joints. Additionally, 439 stainless steel features low cobalt content compared to Type 304, making it particularly suitable for nuclear applications.
When application temperatures exceed the capabilities of 409 stainless steel, 439 provides reliable oxidation and corrosion resistance for automotive exhaust system components and residential furnace primary heat exchangers.
