... as the current fleet of reactors age. Degradation of materials by mechanisms such as intergranular stress corrosion cracking (IGSCC) and primary water stress corrosion cracking (PWSCC) create both technical and regulatory issues. This paper provides an overview of the most significant technical and regulatory...

... ABSTRACT: A number of research works have been conducted for clarification of the mechanism of intergranular stress corrosion cracking (IGSCC) in girth welds of high grade supermartensitic stainless steel (SMSS). Although some evidence indicates that the IGSCC is caused by chromium depletion...

... ABSTRACT This paper addresses the intergranular stress corrosion cracking (IGSCC) problem in the 400 series stainless steel wear rings installed on the pump impeller. The results from the study indicate that the engineering design, the metallurgical heat treatment and the raw water chemical...

..., by TiC formation. However, even if the titanium could suppress the Cr-carbide formation, it was reported that the Ti-alloyed high grade steel girth welds in as-welded condition showed IGSCC along the high temperature HAZ. Therefore, in this study, the effect of phosphorus was also examined...

... ABSTRACT ABSTRACT Low carbon martensitic stainless steels, called supermartensitic stainless steels (SMSS), have widely been applied for flowlines transporting corrosive oil and gas. However, intergranular stress corrosion cracking (IGSCC) in girth welds of the steel has become a major...

... ABSTRACT Supermartensitic stainless steels (SMSS), including both lean grades (without molybdenum) and high grades (with 2% molybdenum), have shown sensitivity to intergranular corrosion or stress corrosion cracking (IGSCC) in weld HAZs during laboratory testing in chloride solutions acidified...

... ABSTRACT Intergranular stress corrosion cracking (IGSCC) in heat affected zone (HAZ) for supermartensitic stainless steel was studied. Two grades of the steel, lean and high grades, were heat- treated for simulating welding thermal cycles. Cracks were observed in some simulated HAZ specimens...

... in the form of fourpoint bend (FPB) testing at 160°C. The test program involved pre-qualification, a robustness study of the post weld heat treatment (PWHT) procedure, welding procedure qualification, and finally a longterm test. The main concern was intergranular stress corrosion cracking (IGSCC). IGSCC...

... tests for austenitic stainless steels and a Ni base alloy. The susceptibility to intergranular stress corrosion cracking (IGSCC) was evaluated by slow strain rate tests (SSRTs), which were performed using a supercritical-water (SCW) test loop. The results for sensitized Type 304 SS indicated...

... ABSTRACT The intergranular stress corrosion cracking (IGSCC) of alloy 600 (UNS N06600) in high temperature water depends upon the microstructure and particularly upon the grain boundary composition and the intergranular carbide distribution. However, has been found that the presence...
