Austenitic stainless steels have excellent corrosion resistance in various environments so they are used as essential material for several parts such as pipeline pumps and structural steel in many industries. Among them 316L stainless steel has good mechanical properties with high corrosion resistance; therefore it is regarded as the one of the most effective materials in various corrosive filed. However in marine atmospheric environments it could be suffered pitting-type corrosion due to seawater and deposition of airborne sea salts which has high chloride concentration. For this reason corrosion protection in high chloride environments is the major concern in many industries at the same time several corrosion mitigation methods are studied and developed in various fields.Vegetable oils are highlited as new effective organic coating which is a nontoxic nondepletable domestically abundant nonvolatile and biodegradable resource. Polar molecules present in the oils can be absorbed on metal surfaces and form the corresponding metal oxides which will enhance the stability of passivation and promote adhesion. Especially sunflower oil (SunFO) coating is reported as a effective corrosion inhibition organic film for carbon steel. However there is seldom studies for corrosion inhibition effect of the sunFO coating for stainless steel and reinforcement effects of the sunFO coating due to synthesis of other materials. Therefore in this study the sunflower oil is used as base coating and binding materials for 316L stainless steel.Recently the two-dimensional (2D) material is extensively researched for the modification of physical properties such as a mixure materials with polymeric organics because they affect corrosion resistance. Among the 2D meterials MoS2 is spotlighted becaues of semiconducting property between the metal and electrolytes. However many modifications such as CVD water transfer for surface coating with MoS2 are being phased out due to their high cost long time in process low throuput and harmful effects on environments. For many researches were conducted to improve stability and corrosion resistance with a mixture between the MoS2 particles and other organic coating material without the toxicant effects.In this study the reinforcement effect of MoS2 in organic coating on 316L stainless steel was investigated in 3.5 % NaCl solution. The electrochemical properties of organic coating according to MoS2 were evaluated by using electrochemical impedance spectroscopy (EIS) tests. Scanning electron microscopy (SEM) with Energy Dispersive Spectrometer (EDS) was used to observe the dispersion of MoS2 on the surface and cross section. In addition X-ray diffraction (XRD) and Fourier-transform infrared spectroscopy (FT-IR) methods were performed to evaluate corrosion resistance of coating materials.

The Effect Of Potassium Hydroxide Primary Water Chemistry On The IASCC Behavior Of 304 Stainless Steel

Product Number: ED22-17415-SG

Author: Michael Ickes, Peter Chou, Kai Chen, Gary Was

Publication Date: 2022

$20.00

The objective of this work was to compare irradiation-assisted stress corrosion cracking (IASCC) growth behavior in simulated pressurized water reactor (PWR) water with pH maintained with LiOH versus KOH. The U.S. nuclear industry is considering changing PWR primary water chemistries to use KOH in place of LiOH, as a means to ensure a stable supply chain and secure cost savings. This experiment will specifically investigate the impact of these alkali ions on the crack growth rate (CGR) and to examine the crack morphologies generated by the CGR experiment.

The effect of reeling on the qualification of CRA lined and clad pipes according to NACE MR0175/ISO 15156-3: a methodology to qualify reeled pipelines

Product Number: 51323-18919-SG

Author: Riccardo Rizzo, Bjarte Lillebø, Stefan Marion, Erik Krogstad Sverre, Mads Arild Eidem, Karl Gunnar Solheim

Publication Date: 2023

$20.00

The use of carbon steel pipelines lined or clad with corrosion resistant alloys (CRAs) is increasing in the O&G industry. These pipelines combine the mechanical properties of carbon steel with the corrosion resistance of CRAs. Some CRAs such as AISI 316L (UNS 31603) are not pre-qualified according to ANSI/NACE MR0175/ISO 15156 part 3. The potential for corrosion and cracking of carbon steel in some applications can require a CRA liner/clad layer to resist corrosion but this can introduce the possible risk of stress corrosion cracking of some CRAs.

Fracture mechanical specimens of the compact tension (CT) type are normally used in tests that study stress corrosion crack (SCC) growth rates (CGR). Normally, the width, W, is twice the thickness, B (W=2B), and B for common specimen sizes is 12.5 or 25 mm. The specimen size can be changed by scaling its dimensions.

The Effect Of Strain On Surface Residual Stress In Alloy 600 Tensile Specimens

Product Number: ED22-17258-SG

Publication Date: 2022

$20.00

Nickel based Alloy 600 is used within the nuclear industry in structural components due to its good mechanical properties and general corrosion resistance, however upon exposure to primary water environments at elevated temperatures it can be affected by Primary Water Stress Corrosion Cracking (PWSCC). Nickel Based Alloy (NBA) susceptibility to PWSCC is dependent on a number of factors that include material type, condition and microstructure, as well as fabrication method, and can be investigated by uniaxial initiation testing in a primary water environment, where specimens are held at constant load under an elevated temperature.

Maintaining the integrity of oilfield equipment is essential to its safe operation and to maximize the efficiency of production. The integrity of oilfield equipment can rely on material selection and control of conditions, however, it is commonly maintained by the applications of chemical corrosion inhibitors (CI). Prior to use, these chemicals must be shown to perform as desired under the field conditions in question. To achieve this, chemicals are often evaluated using robust laboratory-based screening studies to identify potential candidates.
