Liquation Cracking Susceptibility in the HAZ of Nitrogen- Containing Austenitic Stainless steel Welds

摘要

This study was performed to determine the influence of nitrogen additions on liquation cracking Susceptibility in fully austenitic stainless steel SUS310 welds. The nitrogen content varied from 0.023 to 0.325 mass/100. Liquation cracking was investigated using bead-on plate welding, the gleeble test, and the isothermal liquation test. According to the cracking test, it was found that the liquation cracking susceptibility decreased with increasing nitrogen addition.
