Stainless Steel Essay
2.4. Stainless Steel
Stainless steels are described as an iron base alloy, where it is called as inox or inox steel. Stainless steels are steel alloys which contain minimum 10.5 percentage of chromium content. On the surface of stainless steel a thin dense chromium oxide film will form to provide corrosion resistance and further prevents oxidation. Stainless steel is an inoxydable which means it can’t be readily oxidized (incapable of rusting). Stainless steel is notable because of its good corrosion resistance. Increase in Chromium content increases the corrosion resistance in stainless steels. Stainless steels are differing from carbon steels because of chromium content present in it. When compared with stainless steel, carbon steels are readily rusted when reveal to the combination of moisture and air. Due to sufficient chromium presented in stainless steels endure passivation. Further this passive film protects steel surface by blocking diffusion of oxygen and thus protects the bulk metal from corrosion. So stainless steels are used both in corrosion resistance and where strength of steel is required. Stainless steels are roll into tube, wire, bars, plates and sheets where used in surgical instruments, cookware, and in construction material for large

They are
1. Austenitic stainless steel – austenite iron structure is stabilized when nickel is added with it. At low temperature such steel almost be low brittle and non magnetic due to this crystal structure. In stainless steel composition sufficient quantities of manganese has been added to preserves the austenitic structure in steel same as like nickel but cost is low.
2. Ferritic stainless steel - Ferritic stainless steels has good engineering properties when compared with austenitic stainless steel grades. In Ferritic stainless steel nickel and chromium content is low so it has low corrosion resistance. Ferritic stainless steels are normally less

High amount of load acting on the material which is at its recrystallization point tends to deform and then sheet metal is formed. Grey cast iron is used and it is considerably harder as it has some graphite content in its mixture which makes it hard. material Specific features iron Surface

Analysis Of Guns, Germs, And Steel By Jared Diamond
591 Words | 3 PagesJared Diamond, an anthropologist, known for his popular book Guns, Germs, and Steel, originally published in 1997 and updated last in 2005. Guns, Germs, and Steel received the Phi Beta Kappa Science Book Prize (1997), the Pulitzer Prize for nonfiction (1998), and many other awards throughout the years. Within roughly nineteen chapters, Jared Diamond uses his educational background in order to identify why societies are more materially successful than others. Many influential factors such as geography, germs, food production, animal domestication, and the use of advanced technology like steel Diamond claims to be the reasonable belief of why some societies are successful. Many praise Diamond for attempting such a controversial topic in Guns,

1007 Words | 5 PagesAccording to Jared Diamond, “‘History followed different courses for different peoples because of differences among peoples’ environments, not because of differences among people themselves’” (25). Throughout his novel, Guns, Germs and Steel, Jared Diamond traveled 13,000 years into the past in order to masterfully explain the history of the world. Questions such as, “How did the world become so unequal?” and “What factors contributed to the development of the world?” are answered through the means of guns, germs, and steel.

Single Replacement Reactions Lab Report
503 Words | 3 PagesCopper, magnesium, iron, and zinc were all tested in the same five solution compounds; which included hydrochloric acid, sulfate, magnesium chloride, iron chloride, and zinc chloride. Observations of chemical changes within the reaction were recorded to describe the results of the reaction and each metal's reactivity. An example of a single replacement reaction is the Statue of Liberty, which has copper on the outside and iron as an inner support. As time went by, the copper started to react with air and form a verdigris coat, or a bright bluish-green patina. Meanwhile, a single replacement reaction between iron and verdigris takes place so that Verdigris on the outside is replaced back to copper but the iron support is oxidized and rusted.
