Development Of 485 Mpa Class High Strength Low Alloy Steel For Power Plant Infrastructures, Agung Baskoro, Rini Riastuti
Development Of 485 Mpa Class High Strength Low Alloy Steel For Power Plant Infrastructures, Agung Baskoro, Rini Riastuti
Journal of Materials Exploration and Findings
Currently, Indonesia is progressing to build 35,000 MW of power plants, which will increase the demand for materials, especially steel. One of these power plants is fossil fuel-based, which generates not only electricity but also flue gas containing sulfur that may cause corrosion to power plant infrastructure such as chimney or boiler areas. In addition, apart from being resistant to corrosion in sulfuric and hydrochloric acid conditions, the steel used in power plant infrastructure must also have good strength, toughness, and weldability. Therefore, the present paper describes about steel development for power plant applications that has not only corrosion resistance …
Optimization Of Alti Pld Coating By Increasing Ti Content, N2 And Annealing Which Used For Skd61 Pins In Aluminum Die Casting, Rusman Kosasih, Maria Margaretha Suliyanti Prof, Dedi Priadi, Wisnu Usni
Optimization Of Alti Pld Coating By Increasing Ti Content, N2 And Annealing Which Used For Skd61 Pins In Aluminum Die Casting, Rusman Kosasih, Maria Margaretha Suliyanti Prof, Dedi Priadi, Wisnu Usni

The Alumunium Titanium Nitrogen (AlTiN) coating is known as one of the best coating materials for protective coating, while Pulsed Laser Deposition (PLD) is a laser coating process used for electric layer and superconductor applications, producing thin films up to 20 µm in thickness. The combination of these two matters has already been researched and is still in progress. One major challenge in the aluminium casting industry is to minimize the damage caused to tool steel pins made from SKD61, when aluminium material sticks to the pin, and halting production. Therefore, research on effective coatings for tool steels and testing …
Development Of Dynamic Risk-Based Inspection Using Forward Difference Approach For Pipe Failure Due To Uniform Corrosion, Jaka Fajar Fatriansyah, Zahra Nadia Nurullia, Andreas Federico, Dedi Priadi
Development Of Dynamic Risk-Based Inspection Using Forward Difference Approach For Pipe Failure Due To Uniform Corrosion, Jaka Fajar Fatriansyah, Zahra Nadia Nurullia, Andreas Federico, Dedi Priadi
Journal of Materials Exploration and Findings
The oil and gas industry is one of the world's largest and most influential energy contributors. All aspects involved in the operation of this industry are fundamental to be reviewed and managed correctly, especially by preventing or minimizing the failures that could occur. Uniform corrosion is the most common component failure mechanism that can cause failure in the oil and gas industry. The company's actions in managing and preventing the risk of this type of failure have a major role in the sustainability of the company due to the possibility of more significant impacts if the risk cannot be handled …
Effect Of Austenization And Repeated Quenching On The Microstructures And Mechanical Properties Of Wear-Resistant Steel, Yanuar Nugraha, Myrna Ariati Mochtar
Effect Of Austenization And Repeated Quenching On The Microstructures And Mechanical Properties Of Wear-Resistant Steel, Yanuar Nugraha, Myrna Ariati Mochtar
Journal of Materials Exploration and Findings
This study was focused on determining the effect of repeated austenitization and quenching on mechanical properties and microstructure. The experiment was carried out in a rolled quencher facility with a heat treatment process of one to two times, with parameters of an austenizing temperature of 9500C and quenching at a temperature of 8500C with pressurized water media. Testing of specimens, including microstructure observations and hardness testing. The repeated heat treatment process showed an increase in hardness of 0.79% on one-time repeated heat treatment and 1.65% on two repeated heat treatments. This occurs due to the presence accompanied by refinement of …

The Effect Of Graphite And Activated Carbon As Dispersed Particle In Base Fluid As Quench Medium On The Hardness Of S45c Carbon Steel, Wahyuaji Narottama Putra, Danika Aprilia Somadinata, Ghiska Ramahdita
Journal of Materials Exploration and Findings
Adding a solid particle dispersion into a base fluid could increase its thermal conductivity, hence increasing the heat transfer characteristics. One example of this thermally enhanced fluid is in heat treatment industry as quench medium. By controlling the amount of the dispersed particle, the cooling rate of the quench medium can be altered, and could affect steel hardness after heat treatment. In this research, the dispersed particle used was commercially available graphite and activated carbon particle. As for the base fluid, distilled water and common engine oil were compared. The concentration of the dispersed particle was 0.1, 0.3, 0.5 weight …

Mubadala Petroleum operates offshore platforms in a southern Makassar Straits that needs to be periodically inspected. The cost for the inspection is massive due to the high cost of mobilization and demobilization of vessels including crew and equipment. In response of a new approach to reduce cost, a Risk-Based Underwater Inspection (RBUI) methodology is developed. This RBUI purpose is to reduce the inspection interval of the offshore platform, from every 2 years to a longer period[1]. There are existing RBUI methodologies, which are already developed and implemented in other companies[5]. Purpose of this paper is to …
