The Effect of Alloying Elements on Weldability and Corrosion Resistance of Austenitic Stainless Steels(I)
Ho-Shin Jeong, YunYoung Lee, DongSoo Bae
Abstract
  The interest of austenitic heat resistant stainless steels containing high Si has increased because they have higher resistance of oxidation and higher strength at high temperature than STS 310. This study carried out Varestraint test for evaluation of solidification cracking sensitivity of 14 different stainless steels.
  As a result of Varestraint test, all specimens solidified as primary ferrite, and solidification crack sensitivity increased with adding N₂ to shielding gas. Nb and W had beneficial effect on solidification crack resistance in case of less than FN 2 containing, but crack sensitivity increased with Nb and W in case of more than FN 2. Ce had beneficial effect on solidification crack resistance but impaired weld bead appearance.
Key Words: Austenitic stainless steel, Solidification crack, Ferrite number, Varestraint test
