Resistance of the Welded Joint from Supermartensitic Stainless Steel to Sulphide Stress Cracking

Popis výsledku v původním jazyce

The paper is focused on evaluation of resistance of the welded joint made of supermartensitic steel 13Cr6Ni2.5Mo to sulfide stress cracking (SSC). None of the tested samples withstood the required values of loading, failure occurred already at very shorttime intervals. Unsatisfactory resistance can be attributed to high values of mechanical properties of material, which did not sufficiently decrease by tempering, and also to occurrence of undesirable ?-ferrite in structure. In spite of that it was revealed that the welded joint brought even further reduction of resistance to SSC, because the fracture occurred in the samples with welded joint primarily in the weld metal (WM) or in heat affected zone (HAZ) and not in the basic material. More experimentsaimed at confirmation of this trend will be made with samples loaded by lower values of tension.
