The influence of the heat treatment on delta ferrite transformation in austenitic stainless steel weldsS

Shielded metal arc (SMAW) welded specimens using austenitic consumable materials with diffeerent amount of delta-ferrite are annealed in range 650-750 °C through 2-10 hours. Factorial plan 33 with influenced factors regression analyse of measured delta-ferrite values is used. The transformation i.e. decomposition of delta ferrite during annealing was analysed regarding on weld cracking resistance using metallographic examination and WRC-1992 diagram.
