![عکس صفحه اول مقاله: The effects of rolling temperature and sensitization treatment on the sulfide stress corrosion cracking of 304L stainless steel The effects of rolling temperature and sensitization treatment on the sulfide stress corrosion cracking of 304L stainless steel](/preview/png/1469441.png)
The effects of rolling temperature (25 and 150 °C) and sensitization treatment (650 °C/1 h) on the susceptibility to sulfide stress corrosion cracking of 304L specimens were investigated. Regardless of the rolling temperature, the low hydrogen embrittlement (HE) susceptibility was associated with a high α′-martensite content and/or deformability near the notch-fractured location. In contrast, sensitization treatment increased the HE susceptibility of all rolled specimens. Additionally, cracks were observed only on the cold-rolled specimen in the U-bend immersion tests. The superior performance of the warm-rolled specimen in saturated H2S solution was confirmed by both notched tensile and U-bend immersion tests.
► Sulfide cracking of rolled AISI 304L in distinct conditions was conducted.
► Hydrogen embrittlement (HE) caused obviously localized deformation.
► Rolling at room temperature caused a reduced HE susceptibility in tensile tests.
► The WR specimen had better resistance to HE in notched tensile and U bent tests.
► The CR specimen was susceptible to sulfide cracking in the U-bent immersion test.
