The Advantages and Disadvantages of AISI 305 Austenitic Stainless Steel


  • Corrosion Resistance: AISI 305 stainless steel makes it possible to have the best protection against corrosion in different places where it can happen, mild corrosive air and chemical solutions.

  • High Temperature Resistance: It has a mechanical property that allows it to perform at higher temperatures; this makes it ideal for situations where heat protection is paramount.

  • Formability: The formation of the complex structures makes AISI 305 a suitable choice material for AISI 305 forming a good formability that allows an easy fabrication into complex shapes.

  • Weldability: Featuring good weld-ability of this grade of stainless steel allows the materials to be easily welded together with other components.

  • Cost-Effectiveness: In comparison to some higher grades among stainless steels, AISI 305 typically is less expensive which makes it a good pick for some particular applications.


  • Lower Corrosion Resistance: Apart from their corrosion resistance, AISI 305 stainless steels do not have much resistance to the more hostile environments.

  • Reduced Strength: It normally has a shorter mechanical strength than the stainless steels containing higher alloys. This reduces the scope of its applications in high-stress situations.

  • Sensitivity to Chlorides: AISI 305 is prone to chloride-induced breakdown which results in localized corrosion that can appear in the form of pits and crevices.

  • Limited Heat Resistance: Although it still has some mechanical strength at high temperatures, pure AISI 305 is not as resistant to heat as more specialized heat-resistant alloys.

  • Limited Hardening by Cold Working: Contrary to some other stainless steel grades, the AISI 305 has a small hot working capability that this possibly might be an obstacle for its application in those applications that need high strength because of this.
