Rusting of Iron Project Report

Metals and alloys undergo rusting and corrosion. The process by which some metals when exposed to atmospheric condition i.e., moist air, carbon dioxide form undesirable compounds on the surface is known as corrosion. The compounds formed are usually oxides. Rusting is also a type of corrosion but the term is restricted to iron or products made from it. Iron is easily prone to rusting making its surface rough. Chemically, rust is a hydrated ferric oxide. Rusting, an electrochemical mechanism: Rusting may be explained by an electrochemical mechanism. In the presence of moist air containing dissolved oxygen or carbon dioxide, the commercial iron behaves as if composed of small electrical cells. At anode of cell, iron passes into solution as ferrous…

Oxidation Reduction Activity Series

Procedure 1. Place 10 drops of Sodium sulfate, Na2SO4 into well A1 of the 24-well plate. 2. Place 10 drops of Magnesium sulfate, Mg SO4 into well A2 of the 24-well plate. 3. Place 10 drops of Zinc nitrate, Zn(NO3)2 into well A3 of the 24-well plate. 4. Place 10 drops of Iron (III) chloride, FeCl3 into well A4 of the 24-well plate. 5. Place 10 drops of Copper (II) sulfate, Cu SO4 into well A5 of the 24-well plate. 6. Take the metal solids from your LabPaq; there should be one piece each of magnesium, zinc, and iron plus two pieces of lead. Note: Magnesium and lead oxidize very easily and an almost invisible oxidation layer may coat the…

Management and Steel Industry

1. List and elaborate some strategic issues facing NUCOR. Key strategic issues challenging NUCOR include legislation related to climate change, fluctuating cost and supply of iron ore and scrap steel, increasing amount of steel imports, production technology improvements and economic weakness. Changes in legislation could have severe impacts on the firm’s numerous production facilities and could be costly to become compliant. The fluctuations in both the cost and supply of iron ore and scrap steel directly impact the firm’s profitability because it is difficult to pass those costs on to the customers due to the price-driven level of competition in the steel industry. The rise of low cost steel imports increases the domestic U.S. supply which puts pressure on NUCOR….

Dramatic Iron In Tragedy

Dramatic irony is endemic in the experience of the tragedy; people get shocked when tragedy strikes but they will murmur underneath that they had seen it coming though the victims did realize it. Neighbors and friends read signs of death, they are afraid to it directly or try to tell it indirectly and the victims can not believe or just cannot understand. Tragedy sometimes strikes when least expected, Lindsay a beautiful young Woman of two, separated from her husband because he abused her physically, her estranged her husband did not accept the separation though it was authorized by a local judge. He visited her house often and without notifying her in advance, he claimed that house was still his home…

The hardenability of three type of steels

Objective The purpose of the Jominy test in this experiment is to determine the hardenability of three types of steels, namely EN 8, EN 16 and EN 24. Introduction This report will try to illustrate how the hardenability of these types of steels vary and why. This will be done by using the Jominy end quench test on each of the test pieces and then testing the hardness of the particular steel from the quenched end, to the end of the test piece. Taking these different points will enable me to find out how the hardness varies throughout the test piece considering the cooling rate of the metal and thus illustrate the hardenability of the steel. I will also analyse…

What is an alloy?

An alloy is a solid solution or homogeneous mixture of two or more elements where a material with better or different properties is produced. The range of alloys produced depends on the solubility of the constituents and the proportion of them. The number of possible alloy combinations is almost endless since any metal can be alloyed in pairs or in multiples. Alloys can be classified into two main categories:Interstitial alloy. It is when smaller elements, such as boron, carbon, nitrogen, or silicon, fill the spaces or interstice of the main metallic structure or solvent. For example, steel is an interstitial alloy in which carbon atoms fill the holes between the crystal structures of iron. Substitutional alloyIt is formed when the…

Rohm and Haas New Product Marketing Strategy

On May 15, 1984, Joan Macey, Rohm and Haas market manager for Metalworking Fluid Biocides, was reviewing distributor purchases of Kathon MWX, a new biocide that killed microorganisms in metalworking fluids. She found that total sales to distributors for the first five months were 74 boxes against a first-year target of 1,350 boxes. “I have a super product but I can’t sell it,” she said. “I am in the process of reviewing our approach of taking this product to market, but at this point I am not convinced we have a better alternative.” Macey was also responsible for the marketing of Kathon 886 MW, a liquid biocide used in large metalworking fluid tanks (above 1,000-gallon capacity). Kathon 886 MW was…
