Description
EN 1.4510 DIN SUS439M AISI 439 Stainless Steel Sheet
439 stainless steel features a balanced composition that provides a completely ferritic structure at all temperatures, ensuring excellent ductility after welding and superior resistance to intergranular corrosion. Unlike similar ferritic stainless steels such as 430 and 434 alloys, which are susceptible to brittle martensite formation and intergranular corrosion sensitivity in the as-welded condition, 439 stainless steel maintains its properties without requiring post-welding annealing.
This alloy offers exceptional resistance to stress corrosion cracking, excellent weldability, high thermal conductivity, and low thermal expansion characteristics, making it an ideal choice for various demanding applications. The close match of thermal expansion coefficients between 439 stainless steel tubes and carbon steel shells in shell and tube heat exchangers may eliminate the need for expansion joints.
With its low cobalt content compared to Type 304 stainless steel, 439 stainless steel is particularly suitable for nuclear applications. It also provides excellent oxidation and corrosion resistance for automotive exhaust system components and residential furnace primary heat exchangers where application temperatures exceed the capabilities of 409 stainless steel.
