Abstract
Application of stable austenitic steels as structural materials in the temperature range 293 to 4.2 K requires development of welding technologies that provide structure and properties of welds close to those of the base metal. The main problem in welding stable austenitic steels is hot cracking. One the most common procedures to eliminate hot cracking is to form a two-phase welding structure, where the second phase is ferrite, its content being 5 to 10%. However, the addition of delta-ferrite leads to marked embrittlement of welds at 77 to 4.2 K.
