Abstract
This study evaluated changes in delta-ferrite content depending on the preheating of AISI 316L stainless steel. We also determined the reasons for the variation in delta-ferrite content, which affects corrosion resistance. Changes in delta-ferrite content after preheating was confirmed using a Feritscope, and the microstructure was analyzed using optical microscopy.....

DOI:
https://doi.org/10.3365/KJMM.2018.56.4.296
Abstract
347 austenitic stainless steel weld (ASSW) was thermally aged at 343, 400 and 450 °C up to 20,000 h in this study. Effects of thermal aging induced microstructure evolution on the mechanical properties and corrosion resistance of delta-ferrite in the 347 ASSW were qualitatively and quantitatively assessed by high resolution.....

Abstract
To improve the hot-workability of free-machining austenitic stainless steel, we studied the effects of homogenization treatment, Mn/S ratio and the retained δ-ferrite on the hot-workability of 303 austenitic stainless steels. The reduction of area was measured as a function of homogenization temperature in the range of 1160-1250 ℃ and 1-50.....

DOI:
https://doi.org/10.3365/KJMM.2017.55.9.664
Abstract
Austenitic stainless steels have excellent mechanical property and corrosion resistance, and are for these reasons used in demanding applications such as power plant, nuclear reactor and off-shore plant. Especially, austenitic stainless steel 304 (STS304) is mainly used as a pipe material in nuclear power plants. Submerged arc welding (SAW) is.....
