... for the determination of the chloride threshold of stainless steel Abstract Reinforced concrete infrastructure frequently requires maintenance and repair before the designed service life is reached despite the fact that the structure complied with the durability design rules at the time of construction. A major...

... of vibration and to assess fatigue. The SVDL body is constructed from stainless steel (SS) and nickel-aluminum bronze (NAB) materials. Because the SVDL system can be installed at locations ranging from the surface to deep-water, it is subject to a range of temperatures 4–27°C. To protect the SVDL from...

...ABSTRACT Environmental and material limits specified in ANSI/NACE MR0175/ISO15156-3:2015 restrict this use of austenitic stainless steel alloys under sour conditions typically encountered in thermal in-situ oil sand operations. This paper is a follow up study to one presented in 2016 (NACE-2016...

...Two different tube samples were tested during the thermal degradation of DME in order to compare their performances. On the one hand, a standard (non-coated) stainless steel tube (UNS S34700 Austenitic Steel Substrate, hereafter denoted A347) and on the other hand, a coated UNS S34700 tube...

...ABSTRACT Duplex Stainless Steels (DSSs) are an attractive material solution in industry environments where the presence of chlorides and ammonium salts prevent the use of standard austenitic stainless steels, since these contaminants promote severe localized corrosion processes. In refining...

... structures, corrosion-resistant alloys, such as stainless steel (SS), have garnered attention over the past two decades. Different investigations have suggested that the higher material cost may be recovered throughout the service life of structures as the chloride threshold can be as much as an order...

...Low Alloy Steels Stainless Steel Weight Loss Corrosion Rate Measurement Rotation Cage Autoclave INTRODUCTION Abstract Corrosion assessments based on available data or modelling are necessary for end-user material selection, yet there is limited data to specific well conditions. For subsea...

...Abstract A novel approach for performing electrochemical testing on in-situ stainless steel surfaces is presented. This approach involves the use of an absorbent pad placed on the test surface to facilitate the application of standard electrochemical test methods. A detailed description...

.... It is reasonable to assume that the shorted plate is receiving CP currents. The cathodic reactions on the SS GP causes localized alkalinity, promoting the formation of calcareous (calcium carbonate) deposits. Abstract Abnormal localized corrosion of stainless steel 304 components in a Tainter gate system...

Concentrated Solar Power Molten Salt Corrosion Stainless Steel Electrochemistry INTRODUCTION Concentrated solar power (CSP) is one of the renewable energy...

...UNS S30400 stainless steel coupons were prepared by cutting approximately 3 - 4 mm thick coupons from a 12.7 mm diameter rod. Each face of the coupon was ground manually using a series of silicon carbide grit papers from 240 grit to 600 grit. Packs were prepared by thoroughly blending a powder mix...

... to their effect on the corrosion performance. Based on current cases from the industry, products in different material types (including austenitic and duplex stainless steel) are investigated using a range of standardized test methods. This with the goal to gain further understanding of how to conduct quality...

...Abstract Higher grade alloys such as super-duplex stainless steels have been the conventional choice when selecting corrosion resistant alloys (CRAs) for seawater or water-alternative gas (WAG) injection service. However, the use of less costly, leaner alloyed stainless steels has recently been...

Two laser-marking companies and two metallic materials low alloy steel AISI 4140 (UNS G41400) and stainless steel AISI 420M (UNS S42000) were selected for this study. The obtained results indicate that the laser marking...

... the Vacuum Tower Bottom (VTB) solidified in the piping systems. During the unplugging effort, a leak was discovered on a VTB piping circuit constructed of austenitic stainless steel. Therefore, before beginning to restart the unit and the refinery, an investigation had to be carried out to identify...
