En 1.4510 DIN SUS439m AISI 439 Stainless Steel Sheet

En 1.4510 DIN SUS439m AISI 439 Stainless Steel Sheet. Ferritic Structure Stability: Balanced composition ensures ferritic structure at all temperatures, avoiding ductility loss after welding. No Post-Weld Annealing: Does not require annealing after welding to restore ductility or provide intergranular corrosion resistance. Excellent Corrosion Resistance: High resistance to stress corrosion cracking and intergranular corrosion compared to similar alloys like 430. Thermal Expansion Match: Close match of thermal expansion coefficients with carbon steel eliminates need for expansion joints. Low Cobalt Content: Low cobalt content compared to Type 304 makes it attractive for nuclear applications. High Thermal Conductivity: Good weldability, high thermal conductivity, and low thermal expansion characteristics. Automotive & Furnace Use: Provides good oxidation and corrosion resistance for automotive exhaust systems and furnace heat exchangers. Multiple Product Forms: Available in hot/cold rolled wide strip, slit strip, cut sheets, and precision strip.
