Effect of Holding Time on the Corrosion Potential of SS304

摘要: Stainless steels suffer from classical sensitization when encounter at certain temperature which results in precipitation of chromium carbide along grain boundary with simultaneous depletion near boundaries. This study focused on corrosion potential test different condition. The degree was measured based thickness boundary. With increasing holding time, the zone also increases due to diffusion into solid solution. Corrosion showed that heated sample 700°C for 60 minutes resulted highest current density and shifted its more active potential. tend increase precipitation.
