TLDR
In this paper, a heat treatment at a temperature of 900°C for 36 hours followed by water quenching was used to prevent the formation of chromium carbides and promote the diffusion of the chromium back to replenish chromium-depleted zones.Abstract:
Due to different heat treatment procedures being required to reduce intergranular corrosion (IGC) of austenitic AISI 304(ASS304) and ferritic AISI 430(FSS430) stainless steels, this work is aimed at achieving proper heat treatment for these metals simultaneously. Heat treatment at a temperature of 900°C for 36 hours followed by water quenching was an applicable heat treatment procedure for this study. This treatment not only prevented the formation of chromium carbides but also promoted the diffusion of chromium back to replenish chromium-depleted zones.read more

Corrosion of Stainless Steels
TL;DR: In this article, the authors reviewed the corrosion mechanisms of stainless steel and provided a platform for selecting the suitable type of steel for any application with high corrosion resistance, such as pitting and crevice corrosion, intergranular corrosion, stress-corrosion cracking, hydrogen embrittlement, and attack by high-temperature gases.

Determination of susceptibility to intergranular corrosion and electrochemical reactivation behaviour of aisi 316l type stainless steel
TL;DR: In this paper, double loop electrochemical potentiokinetic reactivation (DLEPR) test was applied to determine the degree of sensitization in 316L type stainless steel, where obtained results were correlated with revealed microstructures after oxalic acid test and weight loss measurements of Streicher and Huey acid tests.
