The research was focused to assess the key factors concerning relaxation cracking and how to control it. It included the effect of chemical composition of the base materials (both Fe and Ni base alloys), heat to heat variation, grain size, cold deformation, welding, operating temperature and heat treatments.
Proper heat treatment on stainless steel (SS) heat exchanger tubes is very important to obtain the expected stress corrosion cracking (SCC) and corrosion resistance of the material. This paper will discuss three recent issues that have arisen on this topic.
Metal or thermal spraying is a technology which protects and extends the life of a variety of equipment in hostile environments. This paper presents an experience in utilizing Thermal Spray Coating Technology on top of weld build-up of CS Pressure Vessel eroded shell.
The intent was to understand if the low ferrite limits commonly associated with acceptable toughness in austenitic welds can be used on ASTM A 351 Grade CF3M and CF8M castings.
Metallurgical investigations on a welded sample of 25% Cr super duplex stainless steel (UNS S32750) from a vessel that had operated above 300-350°C (570-660°F) for six months, resulting in brittle fracture.
13Cr Super Martensitic Stainless Steel (SMSS) is commonly used in the Oil & Gas industry. The present work has been aimed at evaluating the influence of different heat treatment processes on the corrosion resistance of 110 ksi 13Cr SMSS.
Additive manufacturing (AM) is a transformative technology that has opened areas of design space that were previously inaccessible by enabling the production of complex, three-dimensional parts and intricate geometries that were impractical to produce via traditional manufacturing methods. However, the extreme thermo-mechanical conditions in the AM build process (e.g., cooling rates ranging from 103 K/sto 106 K/s and repeated heating/cooling cycles) generate deleterious microstructures with high residual stresses, and extreme compositional gradients.
In the present study, thermal effects on the corrosion behavior and corrosion protection performance of TSA coating were investigated using various electrochemical techniques. Heat treatment at higher temperature induces more cracks in the sealer and aluminum coating. Water and corrosive species (e.g., Cl-) penetrate through the cracks, resulting in corrosion of steel substrate.
This paper describes a novel methodology to measure the Critical Pitting Temperature (CPT) of a Duplex Stainless Steels (DSS) in artificial seawater based on the Electrochemical Noise (ECN) technique.
All tests in this program have been performed under simulated PWR primary cooling water conditions. The oxide layer development and morphology is addressed in the literature and more intensively being investigated during the last ten years. The oxide layer that is typically observed under these conditions has a double layer structure. The outer layer is composed of large particles of Fe3O4 and the inner layer mainly consists of small particles of FeCr2O4, e.g.
