Stainless steel commonly react with certain substance that probably will produce some defect whether inner or outer surface. This material contains small casting defects‚ mainly shrinkage cavities‚ due to the manufacturing process. Commonly in industries related to piping system‚ stainless steel pipelines and cylinder tubes are equipment or object that frequently used in our removable insulation installation. In most industrial nowadays‚ stainless steel pipes are frequently exposed to high temperatures

Title: Redox Reaction Introduction: Some of the most important chemical reactions are Redox reactions. They are also known as oxidation-reduction reactions. This reaction passes one or more electrons from one species to another. The species that loses electrons are being oxidized while the species that gains electrons are reduced. The reaction occurs simultaneously. Numbers are given to each element in a chemical reaction to help us find out which element is oxidized and which is

SUMMARY AND CONCLUSION 6.1 Summary Silver nanoparticles are nanoparticles of silver composed of a large percentage of silver oxide due to their large ratio of surface to bulk silver atoms. Various shapes and sizes of nanoparticles are synthesized by physical‚ chemical and biological methods. The Chrysophyllum canito leaf extracts were used for silver nanoparticles synthesis. In this study utterly revealed the best milli molar concentrations of silver nanoparticles synthesis in diverse solvents such

Zone 1: weld metal zone The weld metal zone is where the parent metal and filler metal are heated together to the melting point and then cooled. There are two main microstructural features that can be observed in this zone: they are the Widmanstatten patterns and columnar grains. These patterns are observed to have random directions. The Widmanstatten patterns appear due to large austentite (gamma-Fe) grains being cooled rapidly‚ as steel is a good conductor of heat. The rapid cooling also resulted

The effects of choosing carbon fiber over aluminum The sport of mountain biking has come so far from where it all started back in the late 1970’s. Today when it comes to frame material more and more people are choosing carbon fiber instead of aluminum. But why are they choosing carbon fiber instead of aluminum? Carbon fiber has many advantages that make it better than aluminum. So is carbon fiber really better than aluminum? What is carbon fiber? Carbon fiber is a very lightweight carbon material

Towards the end of Bernhard Schlink’s best-known novel‚ The Reader‚ the narrator is pondering his future after taking his state exam in law. He has just seen his former lover‚ Hanna Schmitz‚ convicted of war crimes: she had been a concentration camp guard‚ something he hadn’t known when she seduced him as a 15-year-old boy. None of the roles he saw played out in court appeals to him: ‘Prosecution seemed to me as grotesque a simplification as defence‚ and judging was the most grotesque oversimplification

description of Electric Iron introduction: An electric iron is a small appliance‚a handheld piece of equipment with a flat‚ roughly triangular metal surface that‚ when heated‚ is used to press clothes to remove creases. Ironing works by loosening the ties between the long chains of molecules that exist in polymer fiber materials. With the heat and the weight of the ironing plate‚ the fibers are stretched and the fabric maintains its new shape when cool. description: The electric iron must have a design
