The Effect of SO₂ Bearing Atmospheres on Fatigue Failure of SAF-2205 AND 316 Stainless-Steel at 700⁰C

Research output: Chapter in Book/Report/Conference proceeding › Chapter › peer-review

Abstract

The effects of sulphur containing gaseous environments and air atmosphere on low cycle fatigue (LCF) failure of SAF 2205 and 316 stainless steel were studied at 700°C. The LCF loading was constant and consisted of creep tension and plastic compression following the CP-Mode of the strainrange partitioning method.
By combining high temperature cyclic loading and sulphur bearing atmosphere in the form of Ar+3%SO₂ environment a severe sulphidation attack took place at the external surface in both SAF 2205 and 316 stainless steel. This attack resulted in the building-up of a cracked sulphide layer, creating initial fatigue cracks which propagated rapidly through the alloy and caused premature failure. The crack propagation was directly controlled by the sulphidation attack at the region ahead of the crack tip. Compared with 316 stainless steel, SAF 2205 duplex stainless steel was more resistant both in Ar+3%SO₂ environment and air atmosphere. This was manifested by a larger number of cycles to failure in both environments.
